FAQ 7: As a Pharmacist what is your recommendation for a patient who is taking Insulin for diabetes melitus and would like to be fasting during the day for a particular period of time to perform his/her religious direction during Holy Ramadaan?

Ramadan is the holy month of fasting in which Muslims refrain from food, fluids, oral medications and smoking from sunrise until sunset. The Koran specifically exempts from fasting those for whom it may have harmful consequences, such as pregnant women, the elderly and those with medical conditions. Fasting is not recommended for type 1 diabetes patients, those who are non-adherent to therapy or who have poor glycemic control [1]. These individuals in particular are at increased risk of hypo- and hyperglycemic episodes as well as metabolic complications associated with dehydration [2]. However, many diabetes patients choose to participate despite the medical and religious advice excusing them from the Ramadan fast [3, 4, 5].

Fortunately, diabetes management strategies during Ramadan have been proposed by international medical and religious bodies [1, 6, 7, 8, 9]. General considerations include pre-Ramadan medical assessment and patient education regarding meal planning; physical activity; the need for increased frequency of blood glucose monitoring and the recognition and management of acute complications. Recommendations for diabetes medication dosing adjustments tailored for both type 1 and type 2 diabetes patients are also outlined. Despite availability of such resources, studies have identified gaps in prescribed diabetes patient care, notably inappropriate health professional discouragement towards fasting and lack of counseling regarding medications or instructions for breaking the fast  [10, 11, 12].

Pharmacists as the front desk healthcare provider has a tremendous role in managing diabetic patients during ramadan.

Pharmacists Recommendations:
At least 1 – 2 months before Ramadan
  • Pre – Ramadan medical assessment
  • Speak to your physician for insulin dose adjustment if needed and individualized advice so as to minimize the risk associated with fasting.
During fasting, especially daytime
  • Monitor your blood sugar levels more frequently especially if you are on insulin therapy or multiple anti-diabetic medications. Test your blood sugar immediately if you experience hypoglycemic symptoms or are feeling unwell.
During Iftar (sunset meal) or Suhur (predawn meal)

Avoid eating too much carbohydrates and fat, especially during Iftar.

  • Drink more water during non-fasting hours
When exercising
  • Avoid excessive rigorous exercise especially before Iftar (sunset meal).
  • Change your exercise timing to about 2 hours after Iftar.

What symptoms to look out for?

  • Chest pain
  • Confusion
  • Dizziness
  • Fruity odour on breath
  • Heart palpitation
  • Muscle cramps
  • Nausea & vomiting
  • Weakness
When you feel unwell/ experience the symptoms above
  • Break your fast
  • Check your blood glucose immediately
  • Seek medical advice immediately if:
    • blood glucose < 3.3 mmol/L (60 mg/dL)
    • blood glucose < 3.9 mmol/L (70 mg/dL) in first few hours after starting of fast
    • Blood glucose > 16.7 mmol/L (300mg/ dL)
  • Call emergency medical service

Avoid fasting on sick days.
