What Are the Causes of Constant Fatigue?
Constant fatigue is defined by Mayo Clinic as chronic tiredness and weariness that results in a lack of energy and an inability to concentrate. Fatigue is accompanied by an intense lack of motivation and a strong desire to sleep, although sleep does not alleviate chronic fatigue. Fatigue is felt by almost everyone at some point, but constant fatigue can indicate underlying conditions or nutritional deficiencies.
