Fatigue
GP, Endocrinologist
Overview
Fatigue is persistent tiredness or lack of energy that does not improve with rest. It can be caused by sleep disorders, anemia, thyroid dysfunction, depression, chronic illness, or lifestyle factors.
When to see a doctor
See a doctor if fatigue is severe, persistent (weeks or months), or accompanied by unexplained weight loss, fever, or other concerning symptoms.
More information
A GP can screen for common causes (anemia, thyroid, sleep apnea). An endocrinologist may be consulted for hormone-related fatigue. Treatment depends on the underlying cause.
