Goitre

Read about diagnosing a goitre. If you think you have a goitre, see your GP. They can examine your neck to see if there's any evidence of thyroid gland swelling.

If you think you have a goitre, see your GP. They can examine your neck to see if there's any evidence of thyroid gland swelling and may request blood tests to check the function of your thyroid gland.

Thyroid function test

A thyroid function test is a type of blood test. A sample of your blood is taken and measured for levels of:

  • thyroid-stimulating hormone (TSH)
  • thyroxine and triiodothyronine (the thyroid hormones) 

If you have lower or higher-than-average levels of these hormones, it could mean you have a thyroid condition or are at risk of developing one in the future.

Referral to a specialist

Your GP may refer you to a specialist thyroid clinic or a specialist in hormone-related conditions (an endocrinologist) if you have a thyroid swelling and:

  • it's getting bigger
  • you have a family history of thyroid cancer
  • you've had radiation treatment to your neck 
  • you have swollen lymph nodes in your neck
  • you're a child or teenager
  • you're 65 or over
  • your voice has changed
  • you're making a high-pitched noise as you breathe (stridor)
  • you're having difficulty breathing or swallowing

If you're referred to a specialist, you may have further tests in hospital. These are described in more detail below.

Radioactive iodine scan

This involves a small amount of radioactive iodine being injected into your vein. The iodine builds up in your thyroid gland, which can then be studied using a special camera.

The scan can provide useful information about the structure and function of your thyroid gland. As the amount of radiation used is very small, it's perfectly safe for most people. However, it may not be suitable if you're pregnant.

Ultrasound scan

An ultrasound scan uses high-frequency sound waves to create an image of part of the inside of your body. It can be used to:

  • build up a picture of the inside of your thyroid gland
  • assess the size of your thyroid gland
  • check whether there are any enlarged nodules in your thyroid gland not found during the physical examination

Fine-needle aspiration

Fine-needle aspiration is a procedure where a sample of the goitre is extracted so the cells inside it can be tested. This procedure is often known as a biopsy

During the procedure, a fine needle on the end of a syringe is inserted into the goitre in your throat. A sample of the fluid or tissue inside the goitre is sucked through the needle into the syringe.

The sample can be examined under a microscope to determine what kind of cells are inside the goitre.

Autoimmune condition
An autoimmune condition is when your immune system (the body’s defence system) produces antibodies (proteins) that should fight infections, but instead attack your body's healthy tissues.
Hormones
Hormones are groups of powerful chemicals produced by the body and have a wide range of effects.
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).
