Which specialist treats hyperthyroidism?

Hyperthyroidism means the thyroid gland is producing too much thyroid hormone. An endocrinologist identifies the likely cause, reviews blood test results, and discusses treatment choices. Depending on the cause and symptoms, the team may also include an eye specialist, surgeon, or nuclear medicine service.

People with hyperthyroidism can notice heat intolerance, excessive sweating, a fast or irregular heartbeat, tremor, weight change, anxiety, or difficulty sleeping. These symptoms can also arise from other health problems, so they need clinical assessment rather than self-diagnosis. A neck swelling may be examined for a goitre and assessed further when needed.

Make a primary care appointment if you have ongoing symptoms that could be related to thyroid hormone changes. Bring prior thyroid results, a full list of medicines and supplements, and details about heart symptoms, eye changes, pregnancy, or plans for pregnancy. Some supplements can affect test interpretation, so mention them even if they are sold without prescription.

If you have been prescribed thyroid medicine, take it as directed and attend planned monitoring. Contact the prescribing team before changing the dose or stopping treatment. The clinician can explain what each test is checking and whether a referral to endocrinology is appropriate.

Seek urgent medical assessment for chest pain, fainting, severe shortness of breath, a very rapid or irregular heartbeat, confusion, or high fever with marked agitation. Get prompt advice for a new painful neck swelling, worsening eye pain or vision change, or symptoms that become rapidly more severe while waiting for review.

Ask what may be causing the hormone changes, whether you need an endocrinology referral, and how often blood tests will be checked. Discuss treatment options, possible medicine side effects, pregnancy planning, eye symptoms, and which symptoms should lead you to contact the team sooner.
