Ramadan Fasting Tips For People With Diabetes


Fasting during Ramadan is one of the Five Pillars of Islam and is obligatory for all healthy adult Muslims. However, people with diabetes may face challenges during fasting due to the risk of hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar).


The decision to fast during Ramadan depends on your individual health condition and should be made in consultation with your doctor. People with diabetes who have well-managed blood sugar levels may be able to fast safely. However, it is important to monitor your blood sugar levels regularly during fasting and to be prepared to break the fast if necessary.


  • Consult your doctor:

Before beginning your fast, it is crucial to talk to your doctor about your intention to fast. They can advise you on how to manage your diabetes during Ramadan and recommend adjustments to your medication or insulin dose. It is important not to make any changes to your diabetes management plan without consulting your doctor first.

  • Plan your meals:

It is essential to plan your meals carefully during Ramadan. The meals should be balanced and contain healthy foods that are low in fat and sugar. It is advisable to break your fast with a light meal consisting of a few dates, a glass of water, and some soup. This helps to stabilize your blood sugar levels and prevent overeating later on.

  • Stay hydrated:

Dehydration can cause serious health complications for people with diabetes, so it is crucial to stay hydrated during Ramadan. You can guard against dehydration in two ways: firstly, by taking fluids on board before dawn and after sunset, and secondly, by limiting the amount of water that you lose during the day. After breaking fast avoid sugary drinks and caffeinated beverages, which can lead to dehydration.

  • Monitor your blood sugar levels:

Monitoring your blood sugar levels is essential during Ramadan. Check your blood sugar levels regularly, especially during the first few days of fasting, to see how your body is responding to the fast. If your blood sugar levels are too high or too low, adjust your medication or insulin dose accordingly.

  • Exercise in moderation:

Moderate physical activity during Ramadan can help to keep your blood sugar levels stable. However, it is essential to avoid strenuous exercise, especially during the hottest part of the day. Instead, opt for light exercise such as walking, yoga, or stretching.

  • Break your fast if necessary:

If you experience any symptoms such as dizziness, weakness, or confusion, break your fast immediately. It is better to break your fast than to risk your health. Remember, fasting is not obligatory for people with diabetes if it poses a risk to their health.


For people with diabetes who are planning to fast during Ramadan, it is essential to eat a healthy and balanced diet during non-fasting hours. This can help to stabilize blood sugar levels and prevent complications. Here are some foods to eat and avoid during Ramadan fasting for diabetics:

Foods to eat:

  1. High-fiber foods: Foods that are high in fiber can help to slow down the digestion of carbohydrates and prevent spikes in blood sugar levels. Examples of high-fiber foods include whole grains, fruits, vegetables, and legumes.

  2. Lean protein: Lean protein sources such as fish, chicken, turkey, and tofu can help to satisfy hunger and prevent overeating during non-fasting hours. Protein also has a minimal effect on blood sugar levels.

  3. Healthy fats: Foods that are rich in healthy fats such as nuts, seeds, avocado, and olive oil can help to reduce inflammation and improve insulin sensitivity.

  4. Low-glycemic index foods: Foods with a low glycemic index, such as non-starchy vegetables, whole grains, and legumes, can help to keep blood sugar levels stable.

  5. Water and other fluids: Staying hydrated is essential for people with diabetes during Ramadan fasting. Drink plenty of water and other fluids between iftar and suhoor.

Foods to avoid:

  1. Processed foods: Processed foods that are high in sugar, salt, and unhealthy fats can cause spikes in blood sugar levels and contribute to inflammation.

  2. Sugary drinks: Beverages that are high in sugar, such as soda, fruit juice, and sweetened tea, can cause spikes in blood sugar levels and contribute to dehydration.

  3. Fried and fatty foods: Foods that are high in unhealthy fats, such as fried foods, fast food, and processed meats, can increase inflammation and insulin resistance.

  4. High-glycemic index foods: Foods with a high glycemic index, such as white bread, white rice, and potatoes, can cause rapid spikes in blood sugar levels.

  5. Caffeinated drinks: Caffeinated beverages such as coffee, tea, and energy drinks can cause dehydration and may interfere with sleep patterns.


In conclusion, Ramadan fasting can be challenging for people with diabetes, but with careful planning and management, it is possible to fast safely. Remember to consult your doctor, plan your meals carefully, stay hydrated, monitor your blood sugar levels, exercise in moderation, and break your fast if necessary. By following these health tips, you can enjoy a safe and healthy Ramadan.
