Can fasting damage your pancreas?

Fasting is known to cause physiological changes in the endocrine pancreas, including decreased insulin secretion and increased reactive oxygen species (ROS) production.

Is fasting bad for pre diabetes?

Eating only during the first eight to 10 hours of the day — a form of intermittent fasting known as “early time-restricted feeding”— makes your body more sensitive to insulin. If you have prediabetes or borderline high blood pressure, your blood sugar levels and blood pressure will normalize.
