Psychological causes of fatigue
Depression, anxiety, adjustment reaction, substance abuse.
Secondary physical causes of fatigue
Side effects of medications, diabetes, hypo- or hyperthyroidism, anemia, acute infection, cardiovascular disease (e.g. congestive heart failure), lung disease (e.g. chronic obstructive pulmonary disease), chronic inflammatory conditions (e.g. rheumatoid arthritis), malignancy, pregnancy and electrolyte imbalances (e.g. hypercalcemia).
Physiologic causes of fatigue
Acute decrease in sleep (e.g., due to parenting a sick child), alternating shift work, and inadequate or poor quality sleep.
The latter may be further broken down into primary sleep disorders (e.g., restless leg syndrome and obstructive sleep apnea), lifestyle issues (increased physical exertion), and medical causes (e.g., sleep interrupted by nocturia or pain).
Primary fatigue causes
Chronic fatigue syndrome and fibromyalgia.
