The kaffara (expiation) for a diabetic patient in Ramadan depends on the type of illness. If the diabetes is chronic, unlikely to improve, and makes fasting harmful, the person breaks the fast and feeds one needy person for every missed day (this is called fidya). If the condition is temporary and recovery is expected, the person simply makes up the missed days after Ramadan. Below we explain both rulings, when diabetics are excused from fasting, and how some can fast safely with their doctor's approval.

Islam takes people's real circumstances into account and does not ask them to worship in ways that cause undue hardship. Allah says: {Allah intends for you ease and does not intend for you hardship} [Al-Baqarah: 185]. People living with diabetes are a clear example. When fasting would damage their health, Islamic law allows them to break the fast, both to lighten their burden and to protect their well-being.
Scholars distinguish between two situations. Here is a quick summary:
| Your situation | What you owe | When to fulfill it |
|---|---|---|
| Chronic diabetes with no expected recovery that prevents fasting | Fidya: feed one needy person for each missed day | Day by day during Ramadan, or later, after Ramadan, at any time |
| A temporary condition expected to improve, with a doctor's advice to break the fast | Make up the missed fasts after Ramadan | Once you are able; postponed further if fasting would endanger your life |
If your diabetes is long-term and fasting puts you at risk, you feed one needy person for every day you do not fast. The measure is half a sa‘ of the local staple food, such as wheat, rice, or dates, which works out to roughly one and a half kilograms. You may give the cash equivalent instead if that serves the poor person better.
Because food prices change, the cash value of fidya is not fixed. Elvefa sets and announces the current amount at the start of Ramadan each year on its Fidya & Kaffarah campaign page.
If your condition is short-term and you are expected to recover, and your doctor tells you to break the fast, you do so and make up those days after Ramadan. If making them up would itself be dangerous to your life, you postpone the make-up fasts until you are well enough.

Breaking the fast becomes a valid concession when a person cannot keep blood sugar under control while fasting. The main situations are:
People with type 1 diabetes are usually excused. They rely on insulin, their blood sugar swings constantly, and missing or reducing doses can lead to severe symptoms and dangerous complications. This decision belongs to a specialist physician.
Patients with type 2 diabetes should not fast if they cannot keep their sugar levels in check or already have lasting complications. If the condition is stable, a doctor may design a meal plan and adjust medication to fit the fasting hours. Regular monitoring and drinking plenty of water between iftar and suhoor are essential.
Someone with serious complications is at risk of a sudden sugar crash, which can cause seizures or fainting. Fasting may also strain the heart and kidneys and affect eyesight, so these patients are advised not to fast.
A diabetes diagnosis does not automatically rule out fasting. With medical approval, these groups may be able to fast:

If your doctor confirms that your diabetes is chronic and fasting is not an option for you, paying fidya is straightforward:

It is best not to. Fasting with diabetes usually means changing medication, doses, and meals, so it should be done under a specialist's supervision, along with drinking enough water.
At suhoor, choose slow-digesting foods with protein, healthy fats, and complex carbs, such as yogurt, oats, eggs, and unsalted nuts. At iftar, start with one to three dates and water, then have a meal with protein like chicken or salmon, plus vegetables, healthy fats, and complex carbohydrates.
Foods loaded with sugar, refined carbs, and unhealthy fats, including sweetened juices, soda, white bread, white pasta, fast food, and processed meats, because they worsen the complications of diabetes.
When your blood sugar is under 70 mg/dL or over 300 mg/dL, or when you develop symptoms such as vomiting, fever, or heart or kidney problems.
Only your doctor should set your schedule. A common approach is to take the usual dose at iftar, drop the lunchtime dose, and cut the suhoor dose by 25 to 50%, but never change your insulin without medical advice.
A person with chronic diabetes who would be harmed by fasting breaks the fast and feeds one needy person per day, while someone with a temporary condition makes up the days later. Either way, talk to your doctor before Ramadan. If you owe fidya, you can pay it through Elvefa's Fidya & Kaffarah campaign so your meals reach families who need them most.
