Why am I always tired? 22 medical reasons for feeling tired

Diabetes

If the heart is the engine driving your body, then sugar is one of the main fuel sources. Diabetics have a problem with the body keeping the sugar in the bloodstream instead of being converted into energy in the body’s cells.This can then result in extreme fatigue when the body has no energy left to function. If you feel perpetually tired, ask your doctor to perform a simple blood test to discover if you have diabetes.Diabetes can be controlled, but it’s important to catch it as early as possible to hold off the more long-term damage it can cause the body.
