Religious populations in UK Distribution of non-Christian religions More than 20% of the Muslim population in the UK suffers from diabetes Office for National Statistics. Religious populations.

Ramadan • Ramadan is the Islamic holy month where fasting is compulsory for all healthy Muslims • Absolute fast between sunrise and sunset • Muslims refrain from: • Food • Liquids • Medication • No restrictions on food or fluid intake between sunset and sunrise Diabetes and Ramadan.

Ramadan • Ramadan is a lunar-based month • Occurs 11 days earlier each year • Not fixed to any season • Duration of the fast can vary from a few hours to more than 20 hours, depending on geographical location and season Benaji et al. Diabetes Res Clin Pract 2006;73:117–25; Al-Arouj et al. Diabetes Care 2005;28:2305–11
Who observes the fast during Ramadan? • Mandatory for healthy Muslims • Exemption for: • Children • Elderly • Sick • Pregnant or nursing mothers • Menstruating women • People with chronic illness (e.g. diabetes, chronic kidney disease, cardiovascular disease) Diabetes and Ramadan.

The Koran specifically exempts sick people from fasting (Al-Bakarah, 183–185) • Patients with diabetes are exempt from fasting during Ramadan • High risk of complications if daily food and fluid intake are markedly altered • More than a permission not to fast • “God likes his permission to be fulfilled, as he likes his will to be executed” • ‘Fidyah’: compensation for not fasting • Fast at later date if possible • Feed the hungry and poor Many Muslims with diabetes insist on fasting during Ramadan. This creates a medical challenges for both patients and physicians. Diabetes and Ramadan. Leicestershirediabetes.

Pathophysiology of fasting in healthy individuals Plasma glucose Glucagon and catecholamines Depleted glycogen stores Insulin secretion Glycogenolysis Gluconeogenesis Low plasma insulin levels Liver Muscle Fatty acid release from adipocytes Generation of ketones Energy Adipose tissue Al-Aroujet al. Diabetes Care 2005;28:2305–11
Risks associated with fasting in patients with diabetes • Glucagon secretion may fail to increase appropriately in response to hypoglycaemia • Severe insulin deficiency may lead to excessive glycogenolysis and increased gluconeogenesis and ketogenesis • Fasting can lead to several complications: • Hypoglycaemia • Hyperglycaemia • Diabetic ketoacidosis • Dehydration and thrombosis Al-Aroujet al. Diabetes Care 2005;28:2305–11
Ramadan affects diet of patients with diabetes Change in frequency of meals • Two meals per day: • Sehri (before dawn) • Iftari (at sunset) Change in dietary patterns • Increase in intake of: • Sugary drinks • Fried foods • Carbohydrate-rich meals • Sweets Diabetes and Ramadan.

Patients at high risk of developing complications during Ramadan Very high risk High risk • Type 1 diabetes • Severe hypoglycaemia or ketoacidosis within last three months prior to Ramadan • Recurrent hypoglycaemia • Sustained poor glycaemic control • Acute illness • Pregnancy • Moderate hyperglycaemia • Renal insufficiency • Advanced macrovascular complications • Living alone and treated with sulphonylurea or insulin • Comorbid conditions that present additional risk factors Al-Aroujet al. Diabetes Care 2005;28:2305–11
General consideration for the management of diabetes during Ramadan • Individualisation • Patient specific recommendations • Frequent monitoring of glycaemia • Crucial for patients with type 1 diabetes and patients with type 2 diabetes who require insulin treatment • This will not break the fast • Nutrition • Healthy and balanced diet • Exercise • Maintain normal levels of physical activity • Breaking the fast • Blood glucose <3.3 mmol/L or >16.7 mmol/L Al-Arouj et al. Diabetes Care 2005;28:2305–11; Dietary advice during Ramadan. Leicestershirediabetes. Available at: http://www.leicestershirediabetes.org.uk//display/templatedisplay1.asp?sectionid=245 (accessed May 2010)
Medical assessment and educational counseling prior to Ramadan • Medical assessment • 1–2 months prior to Ramadan • Assess overall well-being of patients • Check glycaemic control, blood pressure and lipids • Make patient aware of potential risks • Make necessary changes to diet and treatment regimen • Educational counselling • Self-care • Symptoms of hyper- and hypoglycaemia • Blood glucose monitoring • Meal planning • Physical activity • Medication administration • Management of acute complications Al-Aroujet al. Diabetes Care 2005;28:2305–11
Management of patients with type 1 diabetes during Ramadan Poorly controlled Unable to monitor blood glucose levels Very high risk of severe complications Patients should be strongly advised not to fast If patients with type 1 diabetes insist on fasting during Ramadan, their insulin treatment regimen may need to be adjusted Al-Aroujet al. Diabetes Care 2005;28:2305–11
Insulin treatment regimens for patients with type 1 diabetes during Ramadan • Two daily injections of NPH insulin (intermediate-acting) in combination with pre-meal short-acting insulin1 • Before predawn and sunset meals • Increased risk of hypoglycaemia around midday • Long-acting insulin in combination with pre-meal rapid-acting insulin analogues • Once-daily injection of insulin glargine1 or insulin detemir2 • or • Twice-daily injections of insulin detemir2 NPH, neutral protein Hagedorn 1.

Management of patients with type 2 diabetes during Ramadan • Diet-controlled patients • Risk associated with fasting is low in patients who are adequately controlled with diet alone • Potential risk of postprandial hyperglycaemia • Daily exercise programme may need to be modified to avoid hypoglycaemia • Fluid restrictions and dehydration may increase the risk of thrombosis Al-Aroujet al. Diabetes Care 2005;28:2305–11
Management of patients with type 2 diabetes during Ramadan • Patients treated with oral agents • Metformin • Minimal possibility of hypoglycaemia • Timing of doses should be modified • Glitazones • Low risk of hypoglycaemia • No change in dose required • Short-acting insulin secretagogues • Short duration of action • Twice-daily dosing • Sulphonylurea • Increased risk of hypoglycaemia Suitable for use during Ramadan Use with caution during Ramadan Al-Aroujet al. Diabetes Care 2005;28:2305–11
Management of patients with type 2 diabetes during Ramadan • Patients treated with incretin-based therapies Incretin-based therapies GLP-1 receptor agonists DPP-4 inhibitors • Glucose dependent • Low risk of hypoglycaemia • Suitable for use during Ramadan?

Management of patients with type 2 diabetes during Ramadan • Patients treated with insulin • Aim is to maintain adequate basal insulin levels • Intermediate- or long-acting insulin can be used in combination with pre-meal short-acting insulin • Once-daily injection of insulin glargine • Twice-daily injections of NPH insulin or insulin detemir • Dosage of each injection needs to be individualised • Frequent monitoring of blood glucose is required • Overall dose may need to be adjusted depending on weight changes during Ramadan • Potential risk of hypoglycaemia • Patients who have needed insulin therapy for several years • Very elderly patients Al-Arouj et al. Diabetes Care 2005;28:2305–11
The importance of self-monitoring blood glucose • Monitoring glucose is important for successful insulin treatment: • It guides dose adjustment • It allows patients to see the impact of behaviours and diet on glucose • Patients should be encouraged to monitor blood glucose at appropriate intervals • The most important aspect of self-monitoring is that patients use the results Diabetes UK http://www.diabetes.org.uk/Documents/Professionals/primary_recs.pdf (accessed May 2010); NCC-CC http://www.nice.org.uk/Guidance/CG66/Guidance/pdf/English (accessed May 2010); Owens et al.
