Goitre

Read about a goitre (sometimes spelt "goiter"), an abnormal swelling of the thyroid gland that causes a lump to form in the neck.

A goitre (sometimes spelt "goiter") is a swelling of the thyroid gland that causes a lump to form in the front of the neck. The lump will move up and down when you swallow.

The thyroid gland is a small butterfly-shaped gland in the neck, just in front of the windpipe (trachea). It produces thyroid hormones, which help regulate the body's metabolism, the chemical processes that occur in the body.

The size of a goitre can vary from person to person. In most cases, the swelling is small and doesn't cause any symptoms.

In more severe cases, the symptoms may include:

  • coughing
  • a tight feeling in your throat
  • changes to your voice, such as hoarsenes
  • difficulty swallowing (dysphagia)
  • difficulty breathing¬†‚Ästthere may be a high-pitched sound when you breathe (stridor)

Diagnosing a goitre

If you think you have a goitre, see your GP. They'll examine your neck to see whether your thyroid gland is swollen, and may request a thyroid function test to see how well your thyroid gland is working.

A thyroid function test measures the level of certain hormones (chemicals produced by the body) in your blood.

It can show whether you have an underactive or overactive thyroid, both of which are associated with goitre.

If necessary, you may be referred to a specialist in hospital for further tests or treatment.

Treating a goitre

The treatment for a goitre depends on the underlying cause. If the goitre is small and isn't causing any problems, a wait-and-see approach is usually recommended.

Other possible treatments include radioiodine treatment and thyroid surgery.

Although most goitres are usually non-cancerous (benign), it's estimated that in 1 in 20 cases they may be a sign of thyroid cancer.

Causes of a goitre

A goitre can have several possible causes, including:

  • an overactive thyroid gland¬†(hyperthyroidism)
  • an underactive thyroid gland¬†(hypothyroidism)
  • hormone changes during puberty, pregnancy¬†or the menopause
  • not enough¬†iodine (a trace mineral found in fish and plant foods) in your diet
  • taking some types of¬†medication¬†‚Ästsuch as lithium, a medication often used to treat a number of mental health conditions
  • an inflamed thyroid gland (thyroiditis)
  • having¬†radiation treatment to your neck or chest area¬†‚Äď such as radiotherapy¬†for neck cancer
  • nodules or cysts within the thyroid¬†‚Äď most are benign, but should be assessed
  • thyroid cancer¬†‚Äď a rare type of cancer in the UK

Anyone can develop a goitre, but the chances increase with age. Women are also more likely to develop a goitre.

Types of goitre

There are two main types of goitre:

  • diffuse goitre ‚Äď where the entire thyroid gland swells and feels smooth to the touch
  • nodular goitre¬†‚Äď where solid or fluid-filled lumps called¬†nodules develop within the thyroid and make the thyroid gland feel lumpy to touch; the nodules can be single or multiple and may contain fluid (cysts)
Thyroid gland
The thyroid gland is found in the neck. It produces hormones that are released into the bloodstream to control the body's growth and metabolism (the process that turns food into energy).
