Changes in Sexual Functioning in Women and Men in the 5 Years After Bariatric Surgery

Obesity and sexual desire: a systematic review and meta-analysis

BACKGROUND

Impaired sexual functioning is one of the consequences of obesity with hormonal disorders involving testosterone.

AIM

To explore the link between obesity and sexual desire, to assess how changes in body weight affect sexual desire, and to examine the role of testosterone in these changes in obese and overweight men.

METHODS

The systematic review was conducted in PubMed. Studies involving obese/overweight men that reported different libido levels or changes after weight loss interventions were included. Meta-analysis and meta-regression were performed.

RESULTS

The search identified 2259 studies, of which 28 met the eligibility criteria. Most studies focused on weight-loss interventions (n = 21, 77%), with 13 studies investigating the effect of bariatric surgeries. Testosterone levels were reported in 14 studies. The studies encompassed a total population of 18 653 people, including 10 356 obese and overweight men. Of the 28 identified studies, 15 indicated a potential association between BMI, waist circumference, and sexual desire. Effect size meta-analysis (calculated using data from four studies presenting results before and after bariatric surgery) suggests that an increase in the International Index of Erectile Function sexual desire domain was very strongly associated with changes in a patients' weight resulting from bariatric surgery (d = 1.22, 95% CI 0.41-2.03, P = 0.003). The meta-analysis of four studies, presenting results before and after diet intervention, showed a strong impact of weight loss on an increase of the Sexual Desire Inventory (SDI), (d = 1.16, 95% CI 0.44-1.88, P = 0.002) The meta-regression revealed a significant association between the level of sexual desire on the SDI and the magnitude of BMI changes before and after dieting interventions (R2 = 77.97%; P = 0.002). The meta-analysis of plasma total testosterone levels from studies that present results before and after selected diets showed a strong impact of diet on the increase in testosterone levels after interventions (d = 1.39 95% CI 0.86-1.92; P < 0.001). There was a significant impact of the level of plasma total testosterone on the variance of sexual desire in the SDI questionnaire (R2 = 5.33%; P < 0.001).

LIMITATIONS OF EVIDENCE

A lack of studies that focus on sexual desire in obesity, the heterogeneity of the included population, the variability in the used questionnaires and reported statistics.

CONCLUSIONS

A potential association between sexual desire and body weight exists. Weight loss interventions, including dietary changes and bariatric surgery, significantly increased both sexual desire and plasma total testosterone levels. Additionally, variations in plasma total testosterone levels had a significant effect on the variability of sexual desire in obese men.

Sexual and Urinary Health among Women following Bariatric Surgery

PURPOSE

Women with obesity are more likely to experience bothersome urinary and sexual symptoms, but the long-term effect of metabolic and bariatric surgery (MBS) on these outcomes is poorly understood. We aimed to describe how MBS longitudinally impacted women's urinary and sexual health.

METHODS

Patients who underwent MBS at the University of California, San Francisco Medical Center (UCSF) between 2009 and 2021 participated in a survey examining sexual health, pelvic organ prolapse (POP), and urinary health using three validated questionnaires: a modified version of the Female Sexual Function Index (FSFI), the Pelvic Organ Prolapse Distress Inventory 6 (POPDI-6), and the Urinary Distress Inventory 6 (UDI-6). All questions asked referenced two time points: before surgery and at the time of survey. Logistic regression identified predictors of symptom improvement.

RESULTS

Of 162 participants contacted, 118 (73%) had complete survey data. Mean body mass index (BMI) decreased from 52.4 ± 12.6 to 36.3 ± 9.7 kg/m2 (p < 0.01) with an average follow-up of 6 years. The mean UDI-6 score amongst women was 24 ± 24 prior to MBS and 24 ± 26 at the time of survey administration (p = 0.458). Mean modified FSFI scores amongst women were 15 ± 5 prior to surgery and 14 ± 7 at the time of survey administration (p = 0.005). The overall mean POPDI-6 score amongst women was 13 ± 15 prior to surgery and 9 ± 14 at the time of survey administration (p = 0.056).

CONCLUSION

Women who underwent MBS reported a high rate of sexual and urological dysfunction that did not improve longitudinally, despite significant weight loss.

Effects of bariatric surgery on sexual function and fertility: A narrative review

Obesity has emerged as a prevalent global health concern, with its detrimental effects on the reproductive system and sexual function garnering increasing attention. Both men and women affected by obesity face a heightened risk of fertility challenges and sexual dysfunction. Although fertility and sexual function are distinct topics, they are intricately linked and mutually influential in both medical and societal contexts. Bariatric surgery (BS) has generated promising results in alleviating sexual dysfunction and enhancing fertility, results which are often gender specific. In men, improvements in sexual function can often be attributed to weight loss and subsequent optimizations in sex hormone levels. However, improving female sexual function may be related to a range of factors beyond weight loss. Bariatric procedures have shown limited benefits for male fertility; in fact, in some situations it can even be detrimental, leading to a decrease in sperm count and quality. Conversely, BS may positively impact female fertility, improving pregnancy and neonatal outcomes. Nevertheless, it is essential to consider the potential risks related to the adverse effects of malnutrition and rapid weight loss following BS, making it advisable to wait for 12-18 months before attempting pregnancy.

Comparing sexual self-concept in women with obesity pre- and post-bariatric surgery

BACKGROUND

Obesity leads to increased disease burden, decreased life expectancy, and disrupted sexual life. One of the most effective ways of obesity treatment is bariatric surgery. This study was conducted aiming to determine and compare sexual self-concept in women with obesity pre- and post-bariatric surgery.

METHOD

A longitudinal study comparing sexual self-concept pre and post- surgery was conducted on women with obesity referring to obesity clinics in the city of Tehran in 2020-2021. Data collection was performed using Snell's Multidimensional Sexual Self-Concept Questionnaire (MSSCQ), which was completed online. Data were analyzed using SPSS version 16 statistical software and Fisher's exact test, chi-square, Mann-Whitney, independent t, and logistic and linear regression tests. A p-value of less than 0.05 was considered significant.

RESULTS

According to the findings, the mean (standard deviation) score of sexual self-concept was 240.26 (26.82) in the post-surgery group and 200.26 (32.24) in the pre-surgery group (P = 0.001), and the highest mean (standard deviation) score of sexual self-concept both in the pre-surgery group (13.06 [4.00]) and in the post-surgery group (15.46 [2.16]) was related to the area of sexual depression (P = 0.05). Also, with increasing educational level, the odds of bariatric surgery increased by 33%, and those who had no private bedroom had lower odds of bariatric surgery by 65%. In those who did not have other individuals living in their house and their spouse was not a smoker, the self-concept score was 52.35 and 23.11 units higher.

CONCLUSION

In general, bariatric surgery can improve sexual self-care. Considering the issue of sexual self-concept in bariatric surgery, it is recommended to design appropriate counseling and planning before surgery according to the culture of each country.

Sexuality and self-concept of morbidly obese women who are sexually attracted to men after bariatric surgery: a phenomenological study

BACKGROUND

Morbid Obesity (MO) is a public health problem that affects a person's physical, psychological and sexual well-being. Women with MO are affected by their body image and self-concept, and obesity stigma may affect women in social and sexual relationships.

OBJECTIVE

To describe and understand the experiences of morbidly obese heterosexual women (who are sexually attracted to men) in relation to their body image and sexuality after bariatric surgery.

METHODOLOGY

Qualitative study using Merleau-Ponty's hermeneutic phenomenology as a philosophical framework. Data collection took place between 2020 and 2021 in a southern Spanish province. A total of 22 in-depth interviews were conducted using open-ended questions until data saturation was reached.

RESULTS

Two main themes were identified: (1) "Escaping from a cruel environment": weight loss to increase self-esteem; with the sub-themes: 'I love myself now', and 'Body image and social relationships; a vicious circle; (2) "Now, I am truly me": accepting my body to reclaim my sexuality, with the sub-themes: 'The body as the focal point of sexuality', and 'When regaining your sex drive reignites your sex life and relationship'.

CONCLUSION

Weight loss and body acceptance radically change morbidly obese women's sex lives after bariatric surgery. They rediscover their bodies, have increased self-esteem, and see improvements in their social relationships and sexuality. These women feel seen, loved and desired, and now value their body image and femininity. As they go through continuous improvements following bariatric surgery, they gradually regain self-esteem, acceptance of their bodies and control over their sex life. Even though the women's partners benefit from these improvements, they seem to be afraid of being left.

Total and bioavailable 25-hydroxyvitamin D is not associated with improved sexual dysfunction following vitamin D supplementation in women with polycystic ovarian syndrome: a pilot study

BACKGROUND

Vitamin D (Vit D) deficiency has been linked to symptoms of polycystic ovary syndrome (PCOS), yet little is known about Vit D supplementation as a treatment for sexual dysfunction (SDy) in women with PCOS.

AIM

To explore the implications of serum total 25-hydroxyvitamin D (25[OH]D) and bioavailable 25[OH]D (bio-25[OH]D) status and replacement on women with PCOS and SDy.

METHODS

Reproductive-age women with PCOS who were not desiring fertility were eligible provided that they also had SDy, as assessed by the Female Sexual Function Index (FSFI), and were without severe depression, as evaluated by the Beck Depression Inventory II (BDI-II). Participants were given the recommended dietary allowance of Vit D (600 IU daily) plus hormonal contraception (HC; cyclic ethinyl estradiol/drospirenone) or no HC for 6 months. Comparisons between groups were analyzed by chi-square test and t-test, and Pearson's correlation coefficient analyzed correlations between FSFI with demographics, BDI-II, androgen levels, and total and bio-25[OH]D.

OUTCOMES

The outcomes included SDy (FSFI <26.55), total and serum bio-25[OH]D levels, and total and free testosterone.

RESULTS

A total of 42 women without severe depression completed the FSFI, with 28 (66.7%) having SDy. All FSFI domains, including arousal, lubrication, orgasm, and pain, were significantly lower as compared with women without SDy, with no associations with respect to demographics, total and free testosterone, or total and bio-25[OH]D. Vit D replacement was initiated with HC (n = 18) or no HC (n = 10), and for those completing the study, FSFI improved (score >26.55) in 61% (11/18) regardless of the treatment group. A time-treatment effect showed a significant change for the domain of orgasm, suggesting that HC had more of an impact than Vit D replacement. Improvement in sexual function as a dichotomous variable was not associated with age, body mass index, other demographics, total and free testosterone, total and bio-25[OH]D, or HC use.

CLINICAL IMPLICATIONS

Due to the prevalence of SDy in women with PCOS, efficacious treatment options are necessary.

STRENGTHS AND LIMITATIONS

This study is the first to analyze the effect of Vit D supplementation on SDy in women with PCOS. Limitations included the small number of participants who completed the study, thus limiting meaningful conclusions and generalizability.

CONCLUSION

Vit D status was not associated with SDy and BDI-II. While HC may have played a role, standard Vit D supplementation could not account for the noted improvement in FSFI in women with PCOS.

Sexual Function and Satisfaction in the Context of Obesity

PURPOSE OF REVIEW

Sexual dysfunction is commonly associated with overweight/obesity, but the underlying physiological and psychosocial mechanisms are not fully understood. This review contextualizes the obesity-sexual (dys)function relationship, describes recent insights from the medical and social science literature, and suggests opportunities for continued research.

RECENT FINDINGS

Although sexual dysfunction has been historically evaluated as a consequence/outcome of obesity, it is increasingly considered as a harbinger of future metabolic comorbidities, including type 2 diabetes and cardiovascular disease. Body image dissatisfaction is a consistent predictor for lower sexual satisfaction across BMI categories, likely mediated by cognitive distraction during partnered sex. To fully capture the relationship between obesity and sexual dysfunction, multidisciplinary research approaches are warranted. While clinically significant weight loss tends to improve sexual functioning for women and men, higher body image satisfaction may independently promote sexual function and satisfaction without concomitant weight loss.

Endoscopic Assessment Prior to Bariatric Surgery in Saudi Arabia

BACKGROUND

There are marked local inconsistencies in the Arabian Peninsula about the role of preoperative esophagogastroduodenoscopy (EGD) in bariatric surgery. Thus, this study was conducted to determine the frequency of endoscopic and histological findings in the Saudi population presenting for pre-bariatric surgery evaluation.

MATERIAL AND METHODS

This was a retrospective study that included all the patients who were evaluated by EGD at Dammam Medical Complex, Dammam, Saudi Arabia, between 2018 and 2021 as a part of their pre-bariatric-surgery evaluation.

RESULTS

A total of 684 patients were included. They consisted of 250 male and 434 female patients (36.5% and 63.5%, respectively). The mean ± standard deviation for the patients' age and body mass index (BMI) were 36.4±10.6 years and 44.6±5.1 kg/m², respectively. Significant endoscopic or histopathological findings as defined by the presence of large (≥ 2 cm) hiatus hernia, esophagitis, gastroesophageal reflux disease (GERD), Barrett esophagus, gastric ulcer, duodenal ulcer, or intestinal metaplasia were found in 143 patients (20.9%); 364 patients (53.2%) were diagnosed to have Helicobacter pylori infection.

CONCLUSION

The high number of significant endoscopic and histopathological findings in our study supports the routine use of preoperative EGD in all bariatric surgery patients. However, omitting EGD before Roux-en-Y gastric bypass (RYGB) in asymptomatic patients is still reasonable as the most frequently found significant findings, esophagitis, and hiatus hernia, are less likely to impact the operative plans in RYGB. Similarly, active surveillance and treatment of H. pylori infections in obese patients are important but it is not clear whether H. pylori eradication should be done before bariatric surgery.

Perception and Practice of Bariatric Surgery and Reproductive Health in Women: a Cross-sectional Study of Chinese Bariatric Surgeons

BACKGROUND AND PURPOSE

Western studies have explored bariatric surgeons concerning their views on bariatric surgery (BS) and reproductive health, but Asian data were lacking. The aim of this study was to explore the perception and practice of bariatric surgeons on the reproductive health of female patients who underwent BS in China to better guide clinical practice and improve clinical outcomes.

METHOD

An online questionnaire of 31 questions developed by bariatric surgeons was collected by sending to one online communication group (WeChat group) whose members are Chinese bariatric surgeons.

RESULT

A total of 87 bariatric surgeons from mainland China were surveyed. Almost all (97.7%, 85/87) surgeons considered the reproductive health conversation for women who underwent BS to be important or very important. Only 1/4 of surgeons routinely discuss reproductive health-related issues with patients, and only 56% of doctors always ask patients for postoperative contraception. Less than 20% of bariatric surgeons have full knowledge of postoperative contraception, and nearly 40% of them believe that gynecologists should be responsible for providing contraception. More than 35% of bariatric surgeons have never been involved in the co-management of pregnancy in patients with a history of BS.

CONCLUSION

Although most bariatric surgeons are aware of the importance of female reproductive health, there is a large gap in the perception and clinical practice of bariatric surgeons in terms of reproductive health. It is necessary to further strengthen the education of bariatric surgeons and enhance multidisciplinary cooperation with gynecology, obstetrics, and other disciplines to bring better clinical outcomes.

Benefits and Risks of Bariatric Surgery on Women's Reproductive Health: a Narrative Review

Bariatric surgery (BS) is escalating as the most efficient and endurable therapy for severe obesity. Women's reproductive health is essential to women's quality of life and is receiving increasing attention. However, despite the high prevalence of BS among women, the effect of BS on reproductive health remains underemphasis. The purpose of this narrative review is to provide an overview of BS on women's reproductive health, including their reproductive health before, during, and after pregnancy. Although limited attention has been given, current evidence highlights the substantial implications of bariatric surgery on reproductive health and reminds us of the importance of adopting decision-making conversations about reproductive health before bariatric surgery.

Effects of bariatric surgery on testosterone level and sexual function in men with obesity: A retrospective study

INTRODUCTION

Bariatric surgeries induce well-documented weight loss and resolve obesity comorbidities. Sexual function is one of the aspects of life quality and may benefit from surgery. Few studies have revealed the impact of bariatric surgeries on sexual function in Chinese men with obesity.

METHODS

This is a retrospective cohort study of patients undergoing bariatric surgery [laparoscopic sleeve gastrectomy (LSG) or laparoscopic Roux-en-Y gastric bypass (LRYGB)]. Data were collected between September 2017 and February 2022. The International Index of Erectile Function (IIEF) questionnaire was used to evaluate erectile function, intercourse satisfaction, orgasmic function, sexual desire, and overall satisfaction. Sex hormones and other blood tests were evaluated before and at least 1 year after the surgery.

RESULTS

Fifty-nine Chinese male patients completed the IIEF questionnaire. The multivariate logistic regression analysis revealed that body mass index (BMI) was the single independent risk factor of the severity of erectile dysfunction (ED). Preoperative testosterone levels had negative correlations with BMI and waist circumference. Thirty-seven patients completed the postoperative questionnaire with a mean follow-up of 23.2 months.

CONCLUSION

BMI and waist circumference were negatively correlated with testosterone levels. BMI was an independent risk factor for the severity of ED. LSG and LRYGB led to positive and sustained improvement in sexual function of men with obesity. The two procedures had a comparable effect, more subjects being needed. Sex hormone levels also could be reversible. However, more weight loss did not predict a positive change in sexual function. A greater BMI loss might predict a greater increase in testosterone.

Best Practice Contraception Care for Women with Obesity: A Review of Current Evidence

The prevalence of obesity among females of reproductive age is increasing globally. Access to the complete range of appropriate contraceptive options is essential for upholding the reproductive rights of this population group. People with obesity can experience stigma and discrimination when seeking healthcare, and despite limited evidence for provider bias in the context of contraception, awareness for its potential at an individual provider and health systems level is essential. While use of some hormonal contraceptives may be restricted due to increased health risks in people with obesity, some methods provide noncontraceptive benefits including a reduced risk of endometrial cancer and a reduction in heavy menstrual bleeding which are more prevalent among individuals with obesity. In addition to examining systems-based approaches which facilitate the provision of inclusive contraceptive care, including long-acting reversible contraceptives which require procedural considerations, this article reviews current evidence on method-specific advantages and disadvantages for people with obesity to guide practice and policy.

Changes in Marital Status Following Roux-en-Y Gastric Bypass and Sleeve Gastrectomy: A US Multicenter Prospective Cohort Study

Among a US cohort followed 5 years after Roux-en-Y gastric bypass or sleeve gastrectomy, cumulative incidence of marriage and separation/divorce were 18% among unmarried (N=614) and 13% among married (N=827) participants, respectively. Preoperative predictors of marriage included younger age, college degree, lower BMI and cohabitating or being separated (versus single).

Lived Experience after Bariatric Surgery among Patients with Morbid Obesity in East Coast Peninsular Malaysia: A Qualitative Study

Living with morbid obesity is challenging since it affects various dimensions of life. Sustainable weight loss via bariatric surgery helps people suffering from morbid obesity to lead a healthy and meaningful life. This study highlights the challenges before bariatric surgery and the impact on one’s life. A phenomenological approach was employed using in-depth interviews with 21 participants (15 females and 6 males) who had undergone surgery at least 6 months prior to the study with the mean age of 42.6 years. Due to excess body weight, the physical limitation had a serious negative impact on their social life, making them targets of bias and stigmatisation. Surgery was the best option for them to attain sustainable weight loss and to lead a new life. However, a few participants struggled with the side effects of surgery. Five themes were discovered, namely, (1) social restraint; (2) experiencing bias and stigmatisation; (3) bringing new life; (4) boosting self-esteem; and (5) facing the negative side of surgery. This study serves as a platform to explore the difficulties faced by people with morbid obesity and the changes that the participants experienced after the surgery for future intervention to curb the rising number of people with morbid obesity.

Bariatrische Operationen und Schwangerschaft

Hintergrund

Bariatrische Operationen werden weltweit immer häufiger und somit zunehmend an Frauen in reproduktionsfähigem Alter durchgeführt. Das rückt postbariatrische Schwangerschaften mitsamt den damit verbundenen therapeutischen und diagnostischen Besonderheiten automatisch in den Fokus der Gynäkologie.

Fragestellung

Es soll der aktuelle Wissensstand zum Thema bariatrische Chirurgie und Schwangerschaft mit entsprechenden Handlungsempfehlungen gegeben werden.

Material und Methode

Vor dem Hintergrund der verfügbaren Literatur und der klinischen Erfahrung der beteiligten Autoren wurden die wichtigsten Aspekte zusammengefasst.

Resultate

Schwangerschaften nach bariatrischen Operationen kommen immer häufiger vor und erfordern im Falle einer Schwangerschaft gute Kenntnisse der unterschiedlichen Operationstechniken und der sich daraus ergebenden therapeutischen und diagnostischen Konsequenzen. Besonderes Augenmerk sollte dabei auf das engmaschige Monitoring verschiedener Mikronährstoffe gelegt werden, wobei der Zeitpunkt der Schwangerschaft nach bariatrischer Operation eine wichtige Rolle spielt. Die Diagnose einer inneren Hernie nach Magenbypass ist anspruchsvoll und in Verdachtsfällen sollte frühzeitig mit einem erfahrenen adipositaschirurgischen Zentrum Kontakt aufgenommen werden.

Schlussfolgerung

Grundsätzlich ist eine postbariatrische Schwangerschaft für Mutter und Kind unbedenklich, solange eine professionelle und fachgerechte Betreuung der Mütter gewährleistet werden kann.

Female sexual dysfunction after bariatric surgery in women with obesity: A systematic review and meta-analysis

BACKGROUND AND OBJECTIVE

Obesity is prevalent and has a negative impact on women's health, including sexual dysfunction. Recent review articles suggest improvement in Female Sexual Function Index (FSFI) and proportion of female sexual dysfunction (FSD) among women with obesity after bariatric surgery.

METHODS

We pooled data from 16 observational studies involving 953 women. The study outcomes were mean FSFI scores and proportion of FSD before and after bariatric surgery. We also sub-analyzed whether age and duration of follow-up affected these outcomes.

RESULTS

The mean age of the subjects was 39.4 ± 4.2 years. Body mass index (BMI) showed significant reduction postoperatively (p < 0.0001). Bariatric surgery led to significant improvement in total FSFI score (p = 0.0005), and all sexual domains except pain. Bariatric surgery reduced the odds of having FSD by 76% compared with those who did not undergo operation (OR 0.24, 95% CI = 0.17, 0.33, p < 0.0001). Our sub-analysis demonstrated a significant reduction in the proportion of FSD for patients <40 years of age. The improvement of total FSFI scores and reduction in proportion of FSD remained significant within the first 12 months after surgery. Univariate meta-regression showed that BMI was not a significant covariate for improvement of FSFI scores (β = 0.395, p = 0.1, 95% CI = 0.884, 0.095).

CONCLUSIONS

Bariatric surgery is shown to improve sexual function scores and prevalence of FSD. This is especially significant among women <40 years of age. This benefit remained significant within the first year after surgery. This appears to be an additional benefit for these patients.

Sexuality amongst heterosexual women with morbid obesity in a bariatric surgery programme: A qualitative study

AIMS

The objective of this study is to describe and understand the experiences of sexuality amongst heterosexual women with morbid obesity (MO) who are in a bariatric surgery program.

BACKGROUND

Morbid obesity is a chronic, metabolic disease that affects women's physical, psychological and sexual health. MO is associated with anxiety, depression and body image disorders. Bariatric surgery is a reliable method for weight loss in people with MO.

DESIGN

A qualitative descriptive study research design was adopted.

METHODS

Twenty-one heterosexual women with MO in a bariatric surgery program were recruited through purposive sampling. Data collection included individual semi-structured interviews conducted between November 2018 and May 2019. Interviews were audio recorded, transcribed verbatim and analysed using a computer-assisted qualitative data.

FINDINGS

Three main themes emerged from the analysis: (1) trapped in a body that limits my sexuality; (2) between neglect and hope and (3) the partner as a source of support for sexuality in women with MO.

CONCLUSION

Women hide a body that they do not accept and ignore their own sexuality, focusing on that of their partner. Although the women have doubts about their partners' desire for them, they share the decision-making process with them whilst waiting for bariatric surgery, on which they place all of their hopes for improved sexuality and quality of life.

IMPACT

The findings highlight the importance of exploring the experiences and sexual issues faced by heterosexual women with MO in a bariatric surgery program. Bariatric nurses have a privileged position to assess these women's sexuality, recommend alternatives to sexual intercourse or refer them to sexologists. As part of the multidisciplinary team, nurses can contribute to managing the expectations of women with MO and their partners in relation to the improvement of their sex lives following bariatric surgery.

Body perception and sexuality of bariatric surgery patients

PURPOSE

This study aims to determine how body perception and sexual life are affected in obese individuals who are hospitalized to undergo bariatric surgery.

DESIGN AND METHODS

Descriptive research design and the cross-sectional method were used. The study was conducted with 53 individuals who consented to participate. The data were analyzed with the SPSS software package.

FINDINGS

Low body perception and sexual dysfunction were detected, particularly in women.

PRACTICE IMPLICATIONS

In obesity treatment, the psychological and social problems that individuals experience due to obesity should be handled and evaluated with a multidisciplinary approach.

Influence of Gastric Bypass on Obese Women Sexual Function-a Prospective Study

INTRODUCTION

Obesity may lead to hyperandrogenia and affect female sexual function. The study aims to evaluate female sexual function and androgenic profile in obese women after laparoscopic Roux-en-Y gastric bypass (LRYGB).

METHODS

Forty obese women with a mean age of 34 years were prospectively studied. Diabetes and psychiatric and pelvic disorders were the exclusion criteria. All patients underwent LRYGB. Total (TT) and free (FT) testosterone, androstenedione (AD), dehydroepiandrosterone (DHEA) and the Sexual Quotient - Female Version were evaluated, preoperatively, 6 and 12 months after the operation.

RESULTS

Preoperative incidence of sexual dysfunction was 10% and hyperandrogenia was 40%. At 6 months, sexual function was not different; and FT (0.49-0.33 ng/dl) and AD (2.0-1.3 ng/dl) decreased significantly. At 12 months, there was an improvement in female sexual function (77-84 points), related to desire and interest (22-25 points) and comfort (15.9-17.3 points) without case of sexual dysfunction at 12 months. Hyperandrogenia (40-8%), FT levels (0.5-0.3 ng/dl), and AD (2.0-1.4 ng/dl) decreased, while DHEA levels (3.4-4.2 ng/dl) increased. The percentage of weight loss was 22% and 31% at 6 and 12 months, respectively. Sexual function did not correlate with BMI, weight, or androgen levels in any period.

CONCLUSION

Female sexual function in obese women with no diabetes and psychiatric and pelvic disorders improved in patients undergoing LRYGB, especially in desire, interest, and sexual comfort, and this occured after 6 months of the operation and unrelated to BMI, percentage of weight loss, or androgen levels.

KEY POINTS

• In obese women with no diabetes and psychiatric and pelvic disorders the FSD improvement after LRYGB. • FSD no correlation with weight loss and BMI. • FSD no correlation with androgens levels.

Pharmacokinetics of oral levonorgestrel and ethinylestradiol in women after Roux-en-Y gastric bypass surgery

BACKGROUND

Most patients undergoing Roux-en-Y gastric bypass (RYGB) are women in reproductive age. It is not known if bariatric surgery affects the pharmacokinetics of oral contraceptives.

OBJECTIVES

The primary objective was to evaluate ethinylestradiol (EE) and levonorgestrel (LNG) absorption in women undergoing RYGB, compared with nonoperated controls matched by age and body mass index (BMI). A secondary objective was to assess whether the time since surgery and BMI in the postoperative period influenced the absorption parameters.

SETTING

University hospital, Brazil.

METHODS

This study was designed to compare the maximum plasma concentration (Cmax), the time to the peak plasma level (Tmax), the area under the curve (AUC0-8 and AUC0-∞) after a single dose of a combined oral contraceptive with 0.03 mg EE and 0.15 mg LNG among 20 women after RYGB and 20 controls. Blood samples were obtained for 8 hours.

RESULTS

The mean LNG AUC0-8 and LNG AUC0-∞ were higher in RYGB group (P = .048 and P = .004, respectively). We found a positive correlation for LNG AUC0-8 (P = .045) and AUC0-∞ (P = .004) and the time since surgery, and we found a negative correlation for LNG Cmax (P = .018), AUC0-8 (P = .003), and AUC0-∞ (P = .001) and BMI.

CONCLUSION

No significant differences were found in oral EE pharmacokinetics. The operated group showed higher mean LNG AUC0-8 and AUC0-∞ but it was not considered clinically significant. The present study suggests that RYGB may not affect EE and LNG absorption.

Adverse Neonatal and Obstetric Outcomes in a 20-year Brazilian Retrospective Cohort of Pregnancies after Bariatric Surgery

PURPOSE

Evaluation of obstetric and neonatal outcomes in a Brazilian retrospective cohort of pregnancies after Roux-en-Y gastric bypass (RYGB), regarding the 2009 Institute of Medicine (IOM) recommendations about gestational weight gain (GWG) and RYGB-conception interval. Additionally, search for intrapopulation risk factors for small gestational age (SGA) offspring and mental health assessments.

MATERIAL AND METHODS

Retrospective analysis of 132 singleton pregnancies after RYGB. Obstetric and neonatal outcomes were analyzed with stratification in above, below, or meeting the target regarding GWG guidance, and 0-12, 12-47, and ≥48 months for RYGB-conception interval. SGA risk factors were identified through Poisson regression analysis.

RESULTS

GWG below the recommendations was associated with prematurity (p 0.003). Late conceptions (≥48 months) were associated with iron deficiency (p 0.025). Parenteral iron prescription was a protective factor for SGA, with a relative risk of 0.41 (95% CI, 0.20-0.85; p 0.017), and GWG below target was a SGA risk factor, with a relative risk of 4.68 (95% CI, 1.48-14.8; p 0.008). In all, 15.2% of patients had psychopharmacological treatment during pregnancy, and 7.6% received a diagnosis of postpartum depression. Any alcohol and tobacco consumption were reported in 3.8 and 6.8% of patients, respectively.

CONCLUSION

The recommendations regarding GWG apply to the RYGB population, and surgery-conception intervals should be individualized. The parenteral iron prescription was a protective factor for SGA, and GWG below the recommendations of the IOM was a risk factor for SGA. Psychological and psychiatric care should be offered to every possible pregnancy after RYGB.

A review of the psychosocial aspects of clinically severe obesity and bariatric surgery

For the past 2 decades, clinically severe obesity (operationalized as a body mass index ≥40 kg/m2) has increased at a more pronounced rate that less severe obesity. As a result, the surgical treatment of obesity (bariatric surgery) has become a more widely accepted, yet still underutilized, treatment for persons with severe obesity and significant weight-related health problems. Psychologists play a central role on the multidisciplinary team involved in the preoperative assessment and postoperative management of patients. They also have played a central role in clinical research which has enhanced understanding of the psychosocial and behavioral factors that contribute to the development of severe obesity as well as how those factors and others contribute to postoperative outcomes. This article, written specifically for psychologists and other mental health professionals who currently work with these patients or are considering the opportunity to do so in the future, reviews these contributions over the past 20 years. The article highlights how this work has become a fundamental part of international clinical care guidelines, which primarily focus on preoperative psychosocial screening. The article also outlines avenues for future research in the field, with a specific focus on the need for additional behavioral and psychosocial interventions to promote lifelong success after bariatric surgery.

Does sexual functioning improve with migraine improvements and/or weight loss?-A post hoc analysis in the Women's Health and Migraine (WHAM) trial

BACKGROUND

Despite plausibility of migraine headaches contributing to impaired sexual function among women, data are inconsistent and point to obesity as a potential confounder. Prospective studies that assess the relative importance of migraine improvements and weight loss in relation to sexual function could help elucidate associations among migraine, obesity and female sexual dysfunction (FSD).

OBJECTIVE

To evaluate sexual function changes and predictors of improvement after behavioural weight loss (BWL) intervention for migraine or migraine education (ME).

METHODS

Women with migraine and overweight/obesity were randomized to 16 weeks of BWL (n = 54) or ME (n = 56). Participants completed a 4-week smartphone headache diary and the Female Sexual Function Index (FSFI) at pre- and post-treatment. A validated FSFI total cut-off score defined FSD. We compared changes in FSFI scores and FSD rates between conditions and evaluated migraine improvements and weight loss as predictors of sexual functioning in the full sample.

RESULTS

Among treatment completers (n = 85), 56 (65.9%) participants who reported sexual activity at pre- and post-treatment were analysed. Migraine improvements were similar between conditions, whereas BWL had greater weight losses compared with ME. FSD rates did not change overall (48.2% to 44.6%, p = .66) or by condition (BWL: 56.0% to 40.0% vs. ME: 41.9% to 48.4%, p = .17). Similar patterns were observed for changes in FSFI total and subscale scores. Across conditions, larger weight losses predicted greater improvements in FSFI total and arousal subscale scores, whereas larger migraine headache frequency reductions predicted greater improvements in FSFI satisfaction subscale scores.

CONCLUSION

Sexual functioning did not improve with either BWL or ME despite migraine headache improvements in both conditions and weight loss after BWL. However, weight loss related to improvements in physiological components of the sexual response (i.e., arousal) and overall sexual functioning, whereas reduced headache frequency related to improved sexual satisfaction. Additional research with larger samples is needed.

Changes in the sexual functions of male patients and their partners after obesity surgery

Sexual functionality significantly contributes to health-related quality of life and can decrease with obesity. In this study, we aimed to prospectively evaluate the changes that occur in the erection function, sexual function and testosterone level of male patients scheduled to undergo bariatric surgery, as well as the changes in the sexual function of their partner. A total of 40 patients and their partners were included. International Index of Erectile Function-5 (IIEF-5) questionnaire and the Arizona Sexual Experience Scale (ASEX) were filled before and 6 months after surgery by the male patients. The ASEX form was also completed by the partners before and 6 months after the procedure. The height and weight measurements and testosterone values were measured before and after surgery. A statistically significant difference was found between the preoperative and post-operative IIEF-5 scores of the patients (p = 0.000 < 0.01). There was also a statistically significant difference between the patients and their partners' preoperative and post-operative ASEX scores. We can conclude that the partners of men with preoperative erection complaints also experience sexual dysfunction, and with the post-operative decrease in or disappearance of erection complaints, the sexual function of both male patients and their partners improves.

Lifestyle modifications alone or combined with hormonal contraceptives improve sexual dysfunction in women with polycystic ovary syndrome

OBJECTIVE

To describe the prevalence of female sexual dysfunction in a well-defined polycystic ovary syndrome (PCOS) population, and to assess the impact of common PCOS treatments on sexual function.

DESIGN

Secondary analysis of a randomized controlled trial, oral contraceptive pills and weight loss in PCOS.

SETTING

Two academic medical centers.

PATIENTS

Women with PCOS (N = 114) defined by the Rotterdam criteria.

INTERVENTIONS

Continuous oral contraceptive pill (OCP) or intensive lifestyle modification (Lifestyle) or the combination (Combined) for 16 weeks.

MAIN OUTCOME MEASURES

Change in Female Sexual Function Index (FSFI) and Female Sexual Distress Scale-Revised (FSDS-R) scores after 16 weeks.

RESULTS

There was no change in total FSFI or FSDS-R score in any treatment group; however, an increase in the FSFI desire domain subscore was observed in the Lifestyle and Combined treatments, indicating improved sexual desire over the 16-week period. Overall, 33 participants (28.9%) met criteria for sexual dysfunction by FSFI criteria (baseline score ≤26.55). Among this group, FSFI score improved after 16 weeks of Lifestyle and Combined treatments. There was no change in prevalence of sexual dysfunction in treatment groups at 16 weeks. Use of OCPs did not alter FSFI scores.

CONCLUSION(S)

Female sexual dysfunction is highly prevalent among women with PCOS. Our findings suggest that common treatments for PCOS, including intensive lifestyle modification and the combination of intensive lifestyle modification and OCPs, have the potential to improve sexual function in these women; the mechanism for these improvements is likely multifactorial.

A New Beginning: Young Women's Experiences and Sexual Function 18 Months After Bariatric Surgery

Introduction

Female patients expect improved quality of life, including sexual health and regain of fertility after bariatric surgery. Little has been published on to the extent to which patients’ expectations are met by the weight loss after surgery.

Aim

To explore how women perceive the effects of bariatric surgery on quality of life, focusing on sexual health and fertility.

Methods

A qualitative study based on thematic analysis, supported by questionnaire data. Interviews following a semistructured guide were conducted with childless women (n = 11) aged 25–34 years recruited from a university-affiliated Swedish bariatric center. The interviews took place 18 months after surgery in the participants’ homes or at the hospital and were recorded and transcribed verbatim. Data were analyzed with a thematic approach. Questionnaires were filled in at the time of the interviews and compared with preoperative data using a Wilcoxon test for paired data.

Main outcome measures

Participants described experiences related to female sexual health after bariatric surgery. The Hospital Anxiety and Depression Scale and the Female Sexual Function Index questionnaires were administered preoperatively and postoperatively.

Results

“A new beginning” was identified as the master theme, with 3 underlying subthemes: “Being worthy of love,” “Exploring sexuality,” and “Considering parenthood.” The participants described a transformation into being more comfortable with themselves that affected all areas of life, including sexual life. These findings were supported by lower scores for depression, 6.5 vs 2, and improved total Female Sexual Function Index scores, median 23.3 preoperatively and 29.1 postoperatively, P = .012.

Conclusions

Improved body image and enhanced self-esteem play important roles in improved sexual functioning in women after bariatric surgery.

Impact of Bariatric Surgery on Female Sexual Function in Obese Patients: a Meta-Analysis

We aimed to make a meta-analysis regarding the effect of bariatric surgery on female sexual function. PubMed, EMBASE, and CENTRAL were searched from database inception through August 2019. Articles were eligible for inclusion if they examined the effect of bariatric surgery on obese women's sexual function assessed by the Female Sexual Functioning Index (FSFI) or/and the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12). Twenty articles were included into meta-analysis. Bariatric surgery was associated with significant increase in the total FSFI score. When parameters included in the FSFI scoring system were separately evaluated, significant improvements were observed in sexual desire, sexual arousal, lubrication, orgasm, sexual satisfaction, and sexual pain. However, the PISQ-12 and FSFI scores in women with pelvic floor disorders (PFDs) were not significantly changed postoperatively. Bariatric surgery improves female sexual function in obese patients, but not in women with PFD.

The effect of bariatric surgery on female sexual function: a cross-sectional study

The generally negative impact of obesity on female sexuality is well-established. The possible association between bariatric surgery, weight loss, and female sexuality is much less described. The aim of the study was to analyse the possible association between bariatric surgery and female sexual function. It was a cross-sectional study of 623 patients who underwent bariatric surgery between 1999 and 2017. Patients were recruited on the basis of medical records from the Military Institute of Medicine in Warsaw. Patients were invited to complete a questionnaire which consisted of self-designed demographic questions and Female Sexual Function Index (FSFI). The total FSFI score, as well as each subdomain, improved significantly after surgery. The prevalence of low score (< 26.55) was significantly lower after the surgery in comparison to the status prior to the procedure (36.3% vs. 57.5%; p < .001). There were no differences regarding the number of sexually active patients before and after the surgery (75.3% vs. 76.1%; p < .63). There were observed statistically significant, positive correlations between BMI decrease and each subdomain of the FSFI score as well as the total score. Weight loss surgery seems to decrease the risk of sexual dysfunction presence and the advantages are associated with the total BMI loss.

The effect of excess body fat on female and male reproduction

The dramatic increase in the prevalence of obesity coincides with a decline in reproductive health indices in both sexes. Energy excess mediates changes to the regulatory mechanisms of the reproductive system. Obese individuals exhibit increased estrogen concentrations, due to the overexpression of aromatase in the adipose tissue; via a negative feedback loop, men present with symptoms of hypogonadotropic hypogonadism. These hormonal changes, along with increased oxidative stress, lipotoxicity and disturbances in the concentrations of adipokines, directly affect the gonads, peripheral reproductive organs and the embryo. Clinical evidence is somewhat contradicting, with only some studies advocating worse semen parameters, increased incidence of erectile dysfunction, increased doses of ovulation induction medications, and worse live birth rates in assisted reproductive technology (ART) cycles in obese individuals compared with those of normal weight. Similar conclusions are drawn about patients with insulin resistance syndromes, namely polycystic ovary syndrome (PCOS). As far as treatment options are concerned, lifestyle changes, medical therapy and bariatric surgery may improve the reproductive outcome, although the evidence remains inconclusive. In this review, we summarize the evidence on the association of obesity and reproductive health on both the molecular and the clinical level, and the effect of weight-loss interventions on reproductive potential.

Review: Sex-Specific Aspects in the Bariatric Treatment of Severely Obese Women

This systematic literature review aims to point out sex-specific special features that are important in the bariatric treatment of women suffering from severe obesity. A systematic literature search was carried out according to Cochrane and Preferred Reporting Items for Systematic review and Meta-Analysis Protocols (PRISMA-P) guidelines. After the literature selection, the following categories were determined: sexuality and sexual function; contraception; fertility; sex hormones and polycystic ovary syndrome; menopause and osteoporosis; pregnancy and breastfeeding; pelvic floor disorders and urinary incontinence; female-specific cancer; and metabolism, outcome, and quality of life. For each category, the current status of research is illuminated and implications for bariatric treatment are determined. A summary that includes key messages is given for each subsection. An overall result of this paper is an understanding that sex-specific risks that follow or result from bariatric surgery should be considered more in aftercare. In order to increase the evidence, further research focusing on sex-specific differences in the outcome of bariatric surgery and promising treatment approaches to female-specific diseases is needed. Nevertheless, bariatric surgery shows good potential in the treatment of sex-specific aspects for severely obese women that goes far beyond mere weight loss and reduction of metabolic risks.

Mental Health in Bariatric Surgery: Selection, Access, and Outcomes

Severe obesity has many psychiatric consequences that can be influenced by bariatric surgery. The goal of this article is to review these challenges, including the mental health status of patients with severe obesity, the evaluation of surgical candidates, and the early and late effects of the operations, and to offer some recommendations to manage these challenges. The failure of the insurance-mandated preoperative psychosocial evaluation is also discussed.

Changes in total sperm count after gastric bypass and sleeve gastrectomy: the BARIASPERM prospective study

BACKGROUND

The massive weight loss induced by bariatric surgery is associated with major benefits, but the effect on semen variables is still uncertain.

OBJECTIVES

To explore semen modifications with gastric bypass and sleeve gastrectomy.

SETTING

Five French University Hospitals.

METHODS

Male candidates for bariatric surgery with no history of infertility were recruited in this controlled prospective study. Sperm characteristics were collected before surgery and then 6 months and up to 12 months after surgery.

RESULTS

Forty-six adult men who underwent gastric bypass (n = 20) or sleeve gastrectomy (n = 26) were included. Total sperm count tended to be lower at 6 months and showed a significant decrease at 12 months in both surgery groups, at -69.5 million (-96.8 to -42.2 million; P = 0.0021). Total sperm count at 12 months relative to baseline was -41.4 million (P = .0391) after gastric bypass and -91.1 million (P = .0080) after sleeve gastrectomy. This was counterbalanced by an associated resolution of hypogonadism and decrease of DNA fragmentation in most patients with time after surgery.

CONCLUSION

Improvement in some semen variables after bariatric surgery observed in 3 previous studies is in contrast to the lower mean total sperm count found in this study at 1 year. The possible reversibility of this effect in the long term and the impact of surgery on fertility both remain unknown.
