Thyroid Problems: Symptoms & When to See a Doctor
The thyroid gland regulates metabolism. Underactive or overactive thyroid function can cause fatigue, weight change, heart palpitations, or mood shifts. Blood tests guided by a doctor clarify the diagnosis.
Thyroid problems may cause tiredness, weight changes, heat or cold intolerance, heart racing, hair thinning, or neck swelling. A physician can order thyroid blood tests and advise treatment — do not start thyroid hormone on your own.
