South Asian Health — Ramadan & Religious Fasting20 October 2026
For individuals with a history of heart problems, fasting during Ramadan can pose certain risks. Dehydration from not drinking water during fasting hours can strain the heart, especially if you have pre-existing conditions such as hypertension or heart disease. The stress of fasting, combined with potential dietary changes, may also lead to fluctuations in blood pressure and heart rate. It’s crucial to consult your GP before deciding to fast, as they can assess your individual health status and provide recommendations tailored to your needs. If fasting is deemed unsafe, your GP can suggest alternative ways to observe Ramadan that align with your health requirements.
