Fatigue in primary care

Abstract

Fatigue is a common problem in primary care that may represent a reaction to life problems or be a component of a disease state. A careful history, physical examination, and a few directed laboratory tests can usually allow the physician to differentiate between fatigue caused by depression, situational stress, or physical causes such as postviral or drug-induced fatigue, endocrine disorders, sleep disorders, infectious diseases, autoimmune disorders, or neurologic disease. Uncommonly, patients may have otherwise unexplained fatigue lasting 6 months or more that fulfills the criteria of chronic fatigue syndrome. A range of diagnostic skills coupled with a therapeutic physician-patient relationship will usually be successful in treating women with symptoms of fatigue.
