What should you know about puberty goitre?

The thyroid sits at the front of the neck and helps regulate the body's energy use. During puberty, growth and changing hormone needs can coincide with a temporary or persistent enlargement. A goitre may be smooth or lumpy and may occur with normal, low, or high thyroid activity. Possible symptoms include a visible neck swelling, throat pressure, difficulty swallowing, voice change, tiredness, feeling unusually hot or cold, weight change, tremor, or a fast heartbeat.

Book a GP appointment for a new or enlarging neck swelling. The clinician may examine the thyroid and lymph nodes, ask about family history and medicines, and arrange a thyroid function test. Treatment depends on the cause; some people need observation, while others need specialist care or medicine. Do not start iodine or thyroid supplements without medical advice.

Seek urgent care if the swelling causes trouble breathing, choking, inability to swallow, or rapidly worsening neck pressure. Arrange prompt medical review for a new voice change, marked racing heartbeat, fainting, severe weakness, or a swelling that grows quickly. These symptoms do not identify one diagnosis, but they should not wait for a routine appointment.

Ask which thyroid tests are appropriate, whether an ultrasound is needed, and whether the swelling affects school, sport, sleep, swallowing, or breathing. Ask when it should be rechecked and which changes should prompt an earlier visit.
