Fasting in Ramadan and the diabetic patient

Attitudes and habits of patients with type 1 diabetes during fasting Ramadan

OBJECTIVE

Fasting Ramadan is associated with changes in lifestyle patterns of patients with diabetes who choose to perform fasting. We aimed to determine the attitude and habits of patients with type 1 diabetes during fasting Ramadan.

METHODS

The study comprised a prospective cohort of patients with type 1 diabetes who were on insulin pump or multiple daily insulin injections (MDI) regimen. Patient questionnaires included the frequency of self-monitoring of blood glucose (SMBG), the need to make changes in insulin regimen by patients, timings of insulin administration, performing carbohydrate counting and levels of physical activity.

RESULTS

A total of 156 patients were studied (61 patients on insulin pump and 95 patients on MDI). Patients on pump therapy performed SMBG more frequently than those on MDI regimen (4.8 ± 1.4 and 3.7 ± 1.7 times per day, respectively, P = 0.001) and were more likely to perform carbohydrate counting (32.7% and 8.4% of pump and MDI patients, respectively, P < 0.001). There was no difference in the percentage of patients who made changes in insulin doses (74.5% of the pump group and 77.3% of MDI patients) or those who had any level of physical activity (12.5% of the pump group and 21.1% of the MDI group). The timing of administering meal insulin in relation to sunset meal was variable with a preference to taking the injection immediately at sunset. There was no difference in glucose control between both groups as measured by frucotsamine levels or the number of days that patients have to stop fasting.

CONCLUSION

Fasting Ramadan is associated with significant and variable changes in the attitude and behaviors of patients with type 1 diabetes with no difference in glucose control between patients on insulin pump or MDI regimen. Further studies are needed to define the role of education and its effect on these attitudes and patient care in this population.ClinicalTrials.gov Identifier: NCT01941238.

Pulmonary Function of Young Muslim Males During the Month of Ramadan

During the month of Ramadan intermittent fasting (RIF), both dietary and sleep patterns are adversely affected to cope with the rituals of Ramadan. Literature suggests that sleep deprivation and alteration of dietary pattern and nutritional impairment affect the pulmonary structure and function. Pulmonary function during RIF was not explored earlier. The present study aimed to investigate the effects of RIF on pulmonary function tests (PFTs) in healthy young Muslim males. Fifty sedentary nonsmoking healthy young Muslim male individuals of 20 to 25 years of age without any history of pulmonary or other major diseases were recruited by simple random sampling from different parts of Kolkata, India. Participants completed the American Thoracic Society questionnaire to record their personal demographic data, health status, and consent to participate in the study. Expirograph and peak flow meter were used to record the pulmonary function parameters (PFTs). PFTs were within the normal range and did not show any significant variation during the RIF. Body height and body mass depicted significant correlation ( p < .05, p < .001) with PFTs. Tidal volume, vital capacity, and peak expiratory flow rate had significant correlation ( p < .05, p < .01, p < .001) with age. Simple and multiple regression equations were computed to predict PFTs in the studies population. RIF did not affect the normal range of PFTs in young Muslim males of Kolkata, India. Standard errors of estimate of the computed regression equations were substantially small enough to recommend these equations as norms to predict the PFTs in the studied population.

The implications of Ramadan fasting for human health and well-being

Islamic Ramadan is a 29-30 day fast in which food, fluids, medications, drugs and smoking are prohibited during the daylight hours which can be extended between 13 and 18 h · day(-1) depending on the geographical location and season. The majority of health-specific findings related to Ramadan fasting are mixed. The likely causes for these heterogeneous findings lie in the amount of daily time of fasting, number of subjects who smoke, take oral medications, and/or receive intravenous fluids, in the type of food and eating habits and in changes in lifestyle. During Ramadan fasting, glucose homeostasis is maintained by meals taken during night time before dawn and by liver glycogen stores. Changes in serum lipids are variable and depend on the quality and quantity of food intake, physical activity and exercise, and changes in body weight. Compliant, well-controlled type II diabetics may observe Ramadan fasting, but fasting is not recommended for type I, noncompliant, poorly controlled and pregnant diabetics. There are no adverse effects of Ramadan fasting on respiratory and cardiovascular systems, haematologic profile, endocrine, and neuropsychiatric functions.

CONCLUSIONS

Although Ramadan fasting is safe for all healthy individuals, those with various diseases should consult their physicians and follow medical and scientific recommendations.

Ramadan Prospective Diabetes Study: the role of drug dosage and timing alteration, active glucose monitoring and patient education

AIMS

To observe the effects of active glucose monitoring, alteration of drug dosage and timing, dietary counselling and patient education in the occurrence of acute diabetic complications in fasting individuals with diabetes during the month of Ramadan.

METHODS

This prospective study was conducted at the outpatient department of the Baqai Institute of Diabetology and Endocrinology. Two educational sessions, one about drug dosage and timing alteration and glucose monitoring, and the other about dietary and lifestyle modifications, were given to the patients by a doctor and a dietician, respectively. Patients who had been recruited were advised to note their blood glucose readings on a chart for at least 15 fasting days, twice a day with at least one reading in the fasting state.

RESULTS

A total of 3946 readings were obtained in 110 subjects; 82 readings were in the hypoglycaemic range, and there were 22 episodes of symptomatic hypoglycaemia and 60 episodes of biochemical hypoglycaemia observed in 27 patients. Seven patients experienced symptomatic hypoglycaemia, whereas 20 patients had biochemical hypoglycaemia. Symptomatic hypoglycaemic episodes showed a downward trend from weeks 1 to 4. The highest frequencies of hypo- and hyperglycaemic episodes were observed pre-dawn. None of the patients developed diabetic ketoacidosis or hyperglycaemic hyperosmolar state.

CONCLUSION

We observed that, with active glucose monitoring, alteration of drug dosage and timing, dietary counselling and patient education, the majority of the patients did not have any serious acute complications of diabetes during Ramadan.

Adolescents on basal-bolus insulin can fast during Ramadan

Fasting during Ramadan is a major tenet of the Muslim religion. All adults after the age of puberty are required to do so if health permits. However, there are exemptions to this requirement and having a chronic condition such as diabetes is one. Nevertheless, many adults and adolescents feel obliged to fast during Ramadan even though there is no absolute need to do so. This obligation must be respected. There are few data to support this practice in those whose condition, such as diabetes, potentially makes them vulnerable to developing problems during prolonged fasting. This study was designed to examine the ability and safety of young people with diabetes to be able to fast if they so desire. Two groups of patients were studied, those on a multiple injection, so-called basal-bolus, regimen and those on a 'conventional' twice daily pre-mixed insulin regimen. All patients showed a tendency to high blood glucose at the time of commencing their fast. Those on twice daily insulin continued to have hyperglycaemia during the day whilst those on basal-bolus insulin showed a steady fall in blood glucose towards normal by the time of breaking their fast. Although there was a greater tendency to hypoglycaemia in the basal-bolus group, this could be successfully prevented by reducing the dose of basal insulin by 10-20%. We recommend that it is safe for adolescents with diabetes to fast during Ramadan as long as they reduce their basal insulin by this amount and continue to monitor their blood glucose regularly.

Type 1 diabetes and prolonged fasting

AIMS

Fasting is common in several religions. The aims of this study were to determine if prolonged fasting (> 25 h) is safe for individuals with Type 1 diabetes and to identify factors associated with success.

METHODS

Patients intending to fast were instructed on insulin dose adjustments, frequent glucose monitoring and when to terminate the fast using a standard protocol. Clinical and epidemiological factors were recorded and a comparison was made between successful and unsuccessful fasters.

RESULTS

Of 56 subjects who intended to fast, 37 (65%) were successful. Individuals terminated their fast in the presence of either hypoglycaemia or hyperglycaemia and adherence to the protocol was high. There were no serious side-effects of fasting. Successful fasters had greater reductions in insulin dosage and higher HbA(1c). There were no differences between individuals taking intermittent insulin injections and those with continuous infusion pumps.

CONCLUSIONS

Persons with Type 1 diabetes can participate safely in prolonged fasts provided they reduce their usual insulin dose significantly and adhere to guidelines regarding glucose monitoring and indications for terminating fasting.

Diabetes and Ramadan: review of the literature

During the month of Ramadan, Muslims fast every day from dawn to sunset. In the healthy subject, this fasting does not have any harmful consequences on health. However, it can induce several complications for patients with diabetes. The aim of this review twofold: first, it seeks to give some clues about methodological aspect of research during Ramadan and to show the impact of various diabetes monitoring and treatment, including biochemical and clinical parameters, diet and caloric intake, drug intake when fasting. Second, it intends to determine whether or not Ramadan fasting induces complications in patients with types 1 and 2 diabetes and ultimately to elaborate some advice as to the management of fasting patients. Several studies have shown that Ramadan fasting did not alter biochemical parameters in patients with type 2 diabetes. However, other studies have shown that there is either an increase or a decrease in biochemical parameters during Ramadan. Ramadan fasting would be acceptable for patients with well-balanced type 2 diabetes who are conscious of their disease and compliant with their diet and drug intake. If patients with type 1 diabetes wish to fast, it is necessary to advise them to undertake control of their glycaemia several times a day. Patients with type 1 diabetes who will fast during Ramadan may be better managed with fast absorption insulin.
