Updated 2026

How to recognise pathological fatigue

Fatigue is the kind of exhaustion that sleep does not fix. It affects mood, concentration and daily function.

Common causes

Anemia, thyroid dysfunction, poorly-controlled diabetes, depression, sleep apnea, and chronic infections are worth investigating.

When to see a doctor

Fatigue lasting more than 2 weeks, with weight loss, fevers, or shortness of breath needs evaluation.
