Fatigue is very common for people. It is one of the top ten symptoms that people mention to their physicians. Women are at a higher risk than men for developing fatigue – 1.5 times higher. The risk for people to develop fatigue who do not exercise is twice that of active people.
Other risk factors include obesity, alcohol consumption, smoking, depression, high stress levels, anxiety and low blood pressure.
There are many diseases and disorders in which fatigue is a major symptom; for example, cancer, cardiovascular disease, emphysema, multiple sclerosis, rheumatic arthritis, systemic lupus erythematosus, HIV/AIDS, infectious mononucleosis, Chronic Fatigue Syndrome, and Fibromyalgia. The reason for the fatigue is dependent upon the organ system or body function that is affected by the disease.
For example, circulatory and respiratory impairment, infection, nutritional disorders/imbalances, dehydration, deconditioning, pain, stress and sleep disorders.
