What is the first treatment tried for goitre?

A goitre is an enlarged thyroid gland. It may occur when the thyroid is underactive, overactive, inflamed, or affected by nodules. The swelling itself is not treated in the same way for every person. A [Thyroid Function Test](/treatments/diagnostics-and-screening/thyroid-function-test/) helps show whether hormone production is too low, too high, or within the expected range. Further examination or imaging may be considered.

Arrange a [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) for a new or enlarging neck swelling, even if it is not painful. Note changes in swallowing, breathing, voice, weight, energy, heat tolerance, or heartbeat. Do not start iodine or thyroid medicine without advice, because the appropriate treatment depends on the cause.

Seek urgent help if the swelling causes difficulty breathing, noisy breathing, or an inability to swallow fluids. Contact a clinician promptly for rapid enlargement, persistent hoarseness, a hard fixed area, or symptoms of marked thyroid overactivity such as severe palpitations and faintness.

Ask which thyroid tests are needed, whether the swelling suggests nodules, when results will be reviewed, and whether you need imaging or specialist assessment. Ask which changes should prompt earlier review and whether any medicines or supplements could affect thyroid results.
