Your Questions Answered

Q: I have a heart condition. Is it safe to fast during Ramadan?

A: Many people with stable heart disease, hypertension or diabetes can fast safely.
However, if your heart condition is serious or has recently changed—such as after a heart attack, stroke, or heart procedure like a stent or bypass surgery—you may be at higher risk of complications.

Fasting may not be recommended if you have severe heart failure, unstable angina, or uncontrolled hypertension requiring multiple daily doses of medication.
Always discuss your plans with your doctor before fasting. You may also consider trial fasting before Ramadan or intermittent fasting to see how your body copes.

Q: How does fasting affect heart disease and diabetes?

A: Fasting changes how your body regulates blood sugar, blood pressure, and hydration levels.
Dehydration can cause electrolyte imbalances, increasing the risk of arrhythmias.
Diabetic patients may experience dangerously high or low blood sugar levels if their medication schedule is not adjusted.
A well-planned approach can help minimize these risks.
If you feel unwell while fasting, you may be eligible to make up fasting days later in the year or give fidya (charitable donation) instead.

Q: What should I eat during Suhoor and Iftar?

A: At Suhoor (pre-dawn meal), eat slow-digesting foods like oats, brown rice, whole grains, and protein sources such as eggs, beans, or lean meat. Include fiber-rich fruits and vegetables for long-lasting energy.
Avoid salty, fried, or processed foods to prevent dehydration and blood pressure spikes.

At Iftar (breaking the fast), begin with dates and water for gradual energy restoration. Follow with a balanced meal including lean protein, whole grains, and vegetables.
Avoid excessive sugar, heavy, or fried foods to prevent sudden blood sugar spikes and stress on the heart.
Bake or grill your food instead of frying it. Drink plenty of water to stay hydrated except you have heart failure.

Q: Can I change the time I take my medications while fasting?

A: Yes, but only with medical supervision. Some medications, such as blood thinners (e.g., warfarin, digoxin), require careful timing and monitoring. If you take a once-daily or twice-daily medication, you may be able to switch to taking it at Iftar or Suhoor.

Do not stop or adjust your medication without consulting your doctor.

Diabetic patients using insulin may need dose adjustments to avoid hypoglycemia. If a medication must be taken on an empty stomach, consider taking it just before opening your fast.

Q: How can I break my fast safely?

A: Break your fast gradually to avoid overwhelming your system. Start with water and dates before moving on to a light meal.

Monitor your blood sugar levels closely if you are diabetic.

If you take multiple medications, space them out based on your doctor’s advice to prevent blood pressure drops.

Q: What are the warning signs that I should stop fasting?

A: Stop fasting immediately and seek medical help if you experience:

• Severe dizziness or fainting
• Chest pain or shortness of breath
• Extremely high or low blood sugar levels (below 70 mg/dL or above 300 mg/dL)
• Rapid heartbeat or palpitations
• Confusion, excessive sweating, or extreme fatigue
• Swelling in the ankles, breathlessness, or extreme fatigue

Q: Can I exercise while fasting?

A: Light activities such as walking and stretching are beneficial, but avoid strenuous exercise during fasting hours to prevent dehydration and fatigue.
If you are in a cardiac rehabilitation program after a heart event, it may not be safe to fast.
Consult your specialist for guidance.

Q: How can I stay hydrated and avoid complications?

A: Drink plenty of water between Iftar and Suhoor except you being managed for heart failure.

Avoid excessive caffeine and salty foods, as they can cause dehydration.

If you sweat a lot or have an active job, take extra care to maintain hydration levels.
If you have been advised to restrict fluids due to your heart condition, seek medical advice on how to manage during Ramadan.
