South Asian Health — Ramadan & Religious Fasting26 August 2026
Fasting can significantly influence your blood sugar levels, especially for those with diabetes or insulin sensitivity. When fasting, your body uses stored glucose for energy, which can lead to lower blood sugar levels. However, consuming high-sugar foods during Iftar can cause spikes in blood sugar. It's essential to monitor your blood sugar levels regularly and consult your GP if you're on medication for diabetes. They may advise adjusting your medication or meal plans to ensure stable blood sugar levels while fasting. Always prioritize balanced meals with complex carbohydrates, proteins, and healthy fats to maintain stable blood sugar.
