How common is fatigue in depression?

Depression-related fatigue may feel like slowed thinking, heavy movement, low motivation, or needing much more effort for ordinary tasks. Sleep can be disturbed or excessive, and appetite, concentration, and interest may change. Fatigue alone does not diagnose depression; anaemia, thyroid problems, medication effects, sleep disorders, and other conditions can produce similar symptoms.

Tell a clinician how long the fatigue has lasted and whether mood, enjoyment, sleep, appetite, concentration, or functioning have changed. Treatment may include talking therapy, practical support, medicines, or a combination, depending on your assessment. Keep a simple routine with food, sleep, daylight, and gentle movement where possible. Do not stop a prescribed antidepressant suddenly; discuss side effects or concerns with the prescriber.

Arrange an assessment when fatigue persists, interferes with self-care, or comes with low mood or loss of interest. Seek urgent help if you may harm yourself, cannot keep yourself safe, become severely confused, or stop eating and drinking.

Could depression, a physical condition, or a medicine be contributing? Which treatment options suit me? What should I do if my mood worsens or I have thoughts of self-harm?
