Symptom #6: Fatigue
Fatigue is a gradual feeling of tiredness that can be alleviated by periods of rest. It is a nonspecific symptom that can be seen in various conditions and diseases, such as overworking, stress, boredom, jet lag, depression, inadequate sleep, nutritional deficiencies, autoimmune diseases, blood disorders, and cancer. Fatigue can be physical or mental.
Physical fatigue occurs when the body’s muscles are unable to maintain their optimal performance while mental fatigue is a temporary decrease in cognitive performance. Both physical and mental fatigue can manifest as lethargy or somnolence.
