Quick answer
What is Goitre?
A goitre is an enlargement of the thyroid gland, seen or felt as a swelling at the front of the neck that often moves up and down on swallowing. It can be smooth and even, or lumpy (with one or more nodules).
- How it is treated: Treatment depends on the cause, the thyroid function and the size and symptoms of the goitre.
- Self-care: There are no specific lifestyle measures for most goitres, but attending assessment and monitoring, taking any thyroid treatment as prescribed, and reporting a growing swelling or difficulty swallowing or breathing all support good care.
- When to seek help: See a GP about a swelling at the front of the neck, so the thyroid can be assessed.
What it is
A goitre is an enlargement of the thyroid gland, seen or felt as a swelling at the front of the neck that often moves up and down on swallowing. It can be smooth and even, or lumpy (with one or more nodules). A goitre can occur with a thyroid that is underactive, overactive, or working normally, so the symptoms depend on the underlying cause and the size. A large goitre may cause a visible swelling, a feeling of tightness, and occasionally difficulty swallowing or breathing, or a hoarse voice, if it presses on nearby structures. Causes include autoimmune thyroid conditions (such as those causing an under- or overactive thyroid), multiple nodules, iodine-related factors, and others. It is assessed with examination, thyroid blood tests, and usually an ultrasound scan.
How it is treated
Treatment depends on the cause, the thyroid function and the size and symptoms of the goitre. If the thyroid is over- or underactive, that is treated in its own right, which may reduce the swelling. A small goitre with normal thyroid function and no symptoms is often simply monitored. A large goitre causing pressure symptoms (such as difficulty swallowing or breathing), or one where there is concern about a nodule, may be treated with surgery to remove part or all of the thyroid, and in some cases radioactive iodine is used to shrink it. Any lump within a goitre is assessed as for thyroid nodules. Care is guided by the underlying cause and the individual, often with specialist input.

Answers
Goitre: frequently asked questions
What causes a goitre?
An enlarged thyroid can result from autoimmune thyroid conditions (causing an under- or overactive thyroid), multiple nodules, iodine-related factors and others. The thyroid may be underactive, overactive or normal, so assessment checks both the cause and function.
Does a goitre need treatment?
It depends on the cause and size. Any over- or underactivity is treated, a small symptom-free goitre may just be monitored, and a large goitre causing pressure symptoms may be treated with surgery or radioactive iodine.
