The Fainting Fears

The most likely answer is that it’s from dehydration, low blood sugar, or another similar issue rather than a term one.

Dehydration is the most common cause of fainting while fasting. When the body lacks enough fluids, blood volume falls; low blood pressure develops, resulting in dizziness, lightheadedness, and fainting .

Balanced Nutrition : It is crucial to continue consuming nutrient-dense foods that provide lasting energy and help maintain consistent blood sugar levels. Preference should be given to lean proteins, healthy fats, fiber-rich vegetables, and complex carbohydrates. This way, fasting will only improve one’s overall condition and not lead to sudden energy drops.

Also, pay close attention to the signals your body sends you, and adjust your fasting method. If dizziness, weakness, or lightheadedness occurs, immediately stop fasting and eat a small balanced meal. If these symptoms do not go away on their own or even increase, it is worth seeking the advice of a doctor.
