A member asked:

Why does thyroid disease cause fatigue?

A doctor has provided 1 answer

Fatigue: A severe overactive thyroid will likely interfere with sleep and result in fatigue. That needs fairly urgent attention. An underactive thyroid may make you drowsy. That can be corrected by having your doctor check your thyroid levels and optimize your dose.
