How common is feeling anxious in hyperthyroidism?

An overactive thyroid can speed up body processes. Anxiety may occur with a racing or pounding heartbeat, tremor, sweating, heat intolerance, loose stools, weight loss, irritability, or difficulty sleeping. These symptoms can feel similar to a primary anxiety problem, but the combination and physical pattern can point toward thyroid testing.

Feeling anxious by itself does not show that the thyroid is overactive. Stress, medicines, caffeine, heart rhythm problems, and other conditions can cause similar sensations. A clinician may review your history, examine you, and arrange blood tests when appropriate.

Note when anxiety, palpitations, tremor, sweating, bowel changes, or sleep problems occur. List medicines, supplements, energy drinks, and thyroid history for your appointment. Avoid changing prescribed thyroid treatment without medical advice, and reduce stimulants if they clearly worsen symptoms.

Arrange a medical review if symptoms are new, persistent, or accompanied by weight change, heat intolerance, or a fast heartbeat. Treating the underlying thyroid problem may reduce related anxiety, while the clinician also considers separate support for distress.

Seek emergency help for chest pain, fainting, severe breathlessness, marked confusion, or a very fast or irregular heartbeat with feeling unwell. Contact a clinician promptly if symptoms are intensifying or preventing sleep, eating, work, or ordinary activity.

Could thyroid activity contribute to my anxiety and physical symptoms? Which tests are suitable? Could any medicine or supplement be adding to the symptoms? What warning signs should prompt urgent help, and how will treatment be monitored?
