Managing Your Diabetes During Ramadan


Muslims who fast during Ramadan must abstain from eating, drinking, taking oral medications, and smoking; however, there are no restrictions on food or fluid intake between sunset and dawn. Most people consume two meals per day during this month, one after sunset and the other before dawn. In 2023, Ramadan takes place Wednesday March 22 to Thursday April 20.  Eid al Fitr 2023 marks the end of the holy month of Ramadan and will be celebrated on Friday April 21 or Saturday April 22, (depending on the sighting of the moon). The holy month of Ramadan is a time for friends and family to gather and focus on fasting, prayers, and helping people in need. 


Pre-Ramadan Medical Assessment

It is important that you speak with your diabetes team about your wish to observe Ramadan. The diabetes team will perform a pre-Ramadan medical assessment (1-3 months before Ramadan) if possible.  It is also recommended that you follow-up with your diabetes team following Ramadan.


During this appointment you will learn about the following:

  • Importance of glucose monitoring during fasting and non fasting hours
  • To stop the fast if your blood glucose is less than 4.0 mmol/L
  • To stop the fast if your blood glucose is higher than 14.0 mmol/L
  • To stop the fast if you feel ill
  • Medication adjustment (pills and/or insulin), to help prevent low or high blood sugars

  • Meal planning to avoid hypoglycemia and dehydration during fast
  • The appropriate meal choices to avoid postprandial hyperglycemia
  • Advice on the timing and intensity of physical activity during fasting
