Some people feel unusually hungry because glucose is not being used properly by the body’s cells for energy.

Losing weight without trying can occur when the body begins using fat and muscle for energy because glucose is not entering cells effectively.

High blood sugar can leave you feeling tired because your cells may not be getting the energy they need.
