Patients' long-term experiences following obesity surgery with a focus on eating behaviour: A qualitative study

Patients' Pre and Post-Bariatric Surgery Experience of Dieting Behaviours: Implications for Early Intervention

PURPOSE

Bariatric surgery works, in part, by surgically changing signals of hunger and satiety to achieve weight loss. Not all patients experience optimal outcomes. One potential explanation is that post-surgery dieting may subvert the ability to identify physiological cues of hunger and fullness. Dieting behaviours (e.g. restriction/cognitive restraint) are correlated with disordered eating, and disordered eating implicated in poor outcomes. This study examines the experience of dieting after bariatric surgery.

METHOD

Seventeen adult participants who had undertaken bariatric surgery and residing in Australia participated in semi-structured interviews. Surgeries occurred in 2021 (n = 8), 2020 (n = 4), 2019 (n = 2), and one participant each had surgery in 2014, 2009, and 2004. Thematic analysis elicited themes related to post-operative dieting.

RESULTS

All participants reported chronic pre-surgery dieting. Lifestyle change was the overarching post-surgical theme comprising (i) flexibility (e.g. allowing food, intuitive eating), and (ii) control, comprising surgery control (e.g. set portions, surgery instilled control) and dieting control (e.g. discipline, restriction/restraint). Descriptions of lifestyle change often mirrored pre-surgery descriptions of dieting.

CONCLUSION

Post-surgery lifestyle change appears to encompass a tension between flexible/adaptive approaches to eating and the need to maintain control. Control may emerge as practices that mirror pre-surgery dieting with the potential to interfere with adaptive eating behaviours or promote disordered eating. Dieting behaviours may be a precursor to the development of disordered eating. Health care practitioners should regularly assess dieting behaviour post-surgery to enable early intervention where warranted. Future research should consider how post-surgery re-emerging dieting may be identified and measured to aid in intervention.

Dietary experiences after bariatric surgery in patients with obesity: A qualitative systematic review

This systematic review evaluated the dietary experience of patients with obesity post-bariatric surgery. Scopus, CINAHL, Medline, Psych INFO, and Embase databases were searched and JBI Critical Appraisal Tool was used for quality assessment. Thomas and Harden's three-stage thematic synthesis was undertaken using the Enhancing transparency in reporting the synthesis of qualitative research (ENTREQ) statement for reporting. Of the 24 studies extracted, we coded and developed 34 descriptive themes into 7 categories, which were then categorized to 3 analytical themes. The number of all the participants in the 24 articles is 383 people. The results revealed most patients can control their diet for a short period post-surgery. However, this was a matter of gradual self-consciousness as patients also required support and dietary management in postoperative recovery. CLINICAL TRIAL REGISTRATION NUMBER: The protocol for this qualitative systematic review has been registered with PROSPERO (registration number CRD42021229083).

Facing an unexpected reality - oscillating between health and suffering 4-6 years after bariatric surgery

BACKGROUND

Obesity is a significant public health problem that is on the increase worldwide, and treatment with bariatric surgery is becoming more and more common. This type of surgery has proved to be good for weight reduction and for preventing complications, but few studies have investigated patients' long-term experiences of health and suffering.

AIM

To explore people's experiences of health after bariatric surgery. What are their thoughts about their life, body and sexuality?

METHODS

This study is based on semi-structured interviews with eight women and eight men, 4-6 years after bariatric surgery. The data were analysed using qualitative content analysis and resulted in 5 main themes and 14 subthemes.

RESULTS

The new body enabled a healthy life due to better treatment in society, enhanced self-esteem, the pleasure of purchasing clothes and the courage to become more sexually active. At the same time, the body could be experienced as so unfamiliar that their life was dominated by despondency, a lack of freedom and a feeling of being lost, which made them wish to return to their old body.

CONCLUSION AND IMPLICATIONS

The participants received extensive information before as well as follow-up conversations up to one year after surgery. Nevertheless, they all experienced that changing from life as an obese person to a radically reduced body often meant a confrontation with an unexpected reality that oscillated between health and suffering. This indicates that preparedness for the life changes that bariatric surgery may entail is inadequate and that moving towards health and suffering takes its own time. Therefore, more time should be allocated to talking about how life is and can become in the long term, which may facilitate a dialogical, person-centred approach to the setbacks and situations each person needs to manage in order to improve her/his health.

Patients' views of long-term results of bariatric surgery for super-obesity: sustained effects, but continuing struggles

BACKGROUND

Bariatric surgery is a standard treatment for severe obesity, but little is known about patients' perceptions about the long-term impact of such surgery.

OBJECTIVE

The aim of this study was to explore patients' experiences of living with a bariatric procedure for more than a decade.

SETTING

University hospital.

METHODS

At the 10-year follow-up after undergoing Roux-en-Y gastric bypass (RYGB) or biliopancreatic diversion with duodenal switch (BPD/DS), 18 consecutive patients from a previous randomized controlled trial were assessed with a semi-structured interview. Data were analyzed using thematic analysis.

RESULTS

When asked to reflect broadly on their experiences of living with bariatric surgery for over a decade, the participants rarely mentioned procedure-specific issues and complications. Instead, their accounts revealed 2 broad themes: sustained effects after surgery, incorporating subthemes of better health, brighter futures, and better eating and weight regulation, and continuing struggles, including difficulties with physical activity, finding support, helping their children with overweight, and self-criticism. Many positive changes were sustained, but continuing personal struggles were similar to those presurgery.

CONCLUSIONS

Participants expressed overall satisfaction with their bariatric surgery and related outcomes. Most participants acknowledged a continued effect on their appetite, which could be important information for patients who worry about a diminished effect after the first year postsurgery. Participants were prone to self-blame when things did not turn out the way they wanted. Therefore, healthcare providers must build a trustful relationship with their patients, so they will not hesitate to return when they face problems such as weight gain.

Watching, keeping and squeezing time to lose weight: Implications of time-restricted eating in daily life

Time-restricted eating (TRE) is a novel intervention that allows eating and drinking within a certain time window and has shown positive effects on body weight in few studies. Weight loss strategies that easily can be integrated into daily life are needed, but knowledge about how TRE affects daily life is lacking. This study examined how individuals having overweight or obesity at high risk of type 2 diabetes performed TRE in daily life, with a focus on how the timing of eating changed the organisation and rhythms of daily activities. Semi-structured interviews were conducted with participants enrolled in a randomised controlled trial studying the effect of a 12-week TRE intervention focusing on a self-selected daily 10-h window between 6 AM and 8 PM. Seventeen participants from the intervention group were interviewed at baseline and end of intervention, and data were analysed using a thematic analysis approach. Participants found TRE simple and appealing due to the unrestricted dietary intake. In general, participants did not change their food preferences and continued to eat three main daily meals. However, participants had to increase their awareness of the time of day, reshuffle ordinary daily activities and plan their intake more carefully. Two participants reported fully adherence every day, whereas all other participants reported one to several episodes of intake outside their window during the 12 weeks. Social evening activities and collective rhythms were largest barriers. Our findings suggest that TRE interventions would benefit from a broader perspective on daily life and an expanded view on families and friends as joint units of intervention. TRE interventions should consider individuals' daily rhythms and help them develop practical solutions to integrating new eating practices.

Early-phase study of a telephone-based intervention to reduce weight regain among bariatric surgery patients

OBJECTIVE

This study describes early-phase development of a behavioral intervention to reduce weight regain following bariatric surgery. We utilized the Obesity-Related Behavioral Intervention Trials model to guide intervention development and evaluation. We sought to establish recruitment, retention, and fidelity monitoring procedures; evaluate feasibility of utilizing weight from the electronic medical record (EMR) as an outcome; observe improvement in behavioral risk factors; and evaluate treatment acceptability.

METHOD

The intervention comprised 4 weekly telephone calls addressing behavior change strategies for diet, physical activity, and nutrition supplement adherence and 5 biweekly calls addressing weight loss maintenance constructs. Veterans (N = 33) who received bariatric surgery 9-15 months prior consented to a 16-week, pre-post study. Self-reported outcomes were obtained by telephone at baseline and 16 weeks. Clinic weights were obtained from the EMR 6 months pre- and postconsent. Qualitative interviews were conducted at 16 weeks to evaluate treatment acceptability. We aimed to achieve a recruitment rate of ≥ 25% and retention rate of ≥ 80%, and have ≥ 50% of participants regain < 3% of their baseline weight.

RESULTS

Results supported the feasibility of recruiting (48%) and retaining participants (93% provided survey data; 100% had EMR weight). Pre-post changes in weight (73% with < 3% weight regain) and physical activity (Cohen's ds 0.38 to 0.52) supported the potential for the intervention to yield clinically significant results. Intervention adherence (mean 7.8 calls of 9 received) and positive feedback from interviews supported treatment acceptability.

CONCLUSIONS

The intervention should be evaluated in an adequately powered randomized controlled trial. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Adolescent bariatric surgery: a qualitative exploratory study of US patient perspectives

Bariatric surgery is a safe and effective intervention to treat severe obesity and related comorbidities in adolescents. No qualitative studies have explored the perspectives of US adolescent weight-loss patients on their bariatric surgery motivations, decision-making or experiences. The purpose of this qualitative exploratory study was to explore the perspectives of adolescent patients seeking bariatric surgery while enrolled in a medical weight management programme. Eligible participants 13-21 years old were recruited through a weight management programme at a tertiary care children's hospital in the US Midwest. Interviews were conducted remotely using a video chat medium. An initial 60-min semi-structured interview was conducted with seven participants who were 16-21 years old: one deciding on bariatric surgery, one pre-operative and five post-operative. A brief follow-up interview was conducted 1 month later with four participants. Interviews were transcribed and coded using Atlas.ti software. Three broad themes emerged from participants' reflections: the long journey to surgery, time scarcity and be ready for change. The decision to pursue bariatric surgery takes place after struggling with obesity and failed weight-loss attempts since early childhood. Post-operative participants described bariatric surgery as life-changing, but determining when to schedule surgery is a challenge for adolescents.

Patient experiences of outcomes of bariatric surgery: a systematic review and qualitative synthesis

Although bariatric surgery is the most effective treatment for severe and complex obesity, less is known about its psychosocial impact. This systematic review synthesizes qualitative studies investigating the patient perspective of living with the outcomes of surgery. A total of 2,604 records were screened, and 33 studies were included. Data extraction and thematic synthesis yielded three overarching themes: control, normality and ambivalence. These were evident across eight organizing sub-themes describing areas of life impacted by surgery: weight, activities of daily living, physical health, psychological health, social relations, sexual life, body image and eating behaviour and relationship with food. Throughout all these areas, patients were striving for control and normality. Many of the changes experienced were positive and led to feeling more in control and 'normal'. Negative changes were also experienced, as well as changes that were neither positive nor negative but were nonetheless challenging and required adaptation. Thus, participants continued to strive for control and normality in some aspects of their lives for a considerable time, contributing to a sense of ambivalence in accounts of life after surgery. These findings demonstrate the importance of long-term support, particularly psychological and dietary, to help people negotiate these challenges and maintain positive changes achieved after bariatric surgery.

Patients' strategies for eating after gastric bypass surgery: a qualitative study

BACKGROUND/OBJECTIVES

There is considerable variation in the amount of weight patients lose after gastric bypass surgery, and this may be related to the way they adjust to the operation in their daily eating practices. Little is known about how this varies. On the basis of a qualitative research design, this study therefore explores how patients deal with gastric bypass surgery in their daily lives.

SUBJECTS/METHODS

The study is based on interviews with 24 men and women in Denmark diagnosed with morbid obesity who have had, Roux-en-Y gastric bypass surgery. The interviews were transcribed, coded and analysed using 'grounded theory' methodology.

RESULTS

Three strategies used by patients to cope with postoperative changes were identified. In the first strategy, patients treat surgery as time-out, using the operation to facilitate a change in their ordinary habits of daily life, but not as a solution to overweight in itself. Patients adopting the second strategy of surgery as solution would expect their smaller stomach to hinder excess food intake automatically. The third strategy of abstaining was adopted by patients who were afraid to experience negative side effects, or who believed they might 'ruin the operation'.

CONCLUSIONS

Patients adjust to their postoperative condition in very different ways. The variation in the ways patients comprehend and cope with the operation and in its effects on their eating routines and practices needs to be further investigated and compared more systematically with the outcomes of the operation in terms of weight loss and overall well-being.

The association between chronic pain and obesity

Obesity and pain present serious public health concerns in our society. Evidence strongly suggests that comorbid obesity is common in chronic pain conditions, and pain complaints are common in obese individuals. In this paper, we review the association between obesity and pain in the general population as well as chronic pain patients. We also review the relationship between obesity and pain response to noxious stimulation in animals and humans. Based upon the existing research, we present several potential mechanisms that may link the two phenomena, including mechanical/structural factors, chemical mediators, depression, sleep, and lifestyle. We discuss the clinical implications of obesity and pain, focusing on the effect of weight loss, both surgical and noninvasive, on pain. The literature suggests that the two conditions are significant comorbidities, adversely impacting each other. The nature of the relationship however is not likely to be direct, but many interacting factors appear to contribute. Weight loss for obese pain patients appears to be an important aspect of overall pain rehabilitation, although more efforts are needed to determine strategies to maintain long-term benefit.
