How can fasting impact your body’s electrolyte balance?

South Asian Health — Ramadan & Religious Fasting17 September 2026
Fasting during Ramadan can significantly impact your body's electrolyte balance due to the long hours without food and drink. Electrolytes like sodium, potassium, and magnesium are crucial for muscle function, hydration, and overall health. When you fast, especially in hot weather, you may lose electrolytes through sweat and urine, leading to symptoms like fatigue, dizziness, and muscle cramps. To maintain balance, it’s important to consume electrolyte-rich foods during suhoor and iftar. Foods like bananas, nuts, and yogurt can help replenish lost electrolytes. Additionally, drinking plenty of water between iftar and suhoor is essential to prevent dehydration and maintain optimal health during Ramadan. If you have concerns about your electrolyte levels, consult your GP or healthcare provider.
