What should I do if I feel weak or lightheaded while fasting?

Feeling weak or lightheaded while fasting can be concerning. First, it's important to listen to your body. If you experience these symptoms, consider breaking your fast and hydrating with water or an electrolyte drink. Eating a light meal with carbohydrates and proteins can also help restore energy levels. If symptoms persist, it's crucial to consult with a healthcare professional, as it may indicate dehydration or low blood sugar. The NHS recommends that anyone with underlying health conditions should have a plan in place for managing their health during fasting.
