What is the thyroid gland?

The thyroid gland is a structure in your neck that produces a hormone called thyroxine, which regulates your body's metabolism.

Your thyroid gland has become overactive and is producing too many hormones. This is called thyrotoxicosis and can lead to some distressing symptoms such as losing weight, tremors, sweatiness, being unable to cope with heat, difficulty sleeping and eye problems.

What are the benefits of surgery?

Your body will stop producing thyroid hormones so you should no longer have any distressing symptoms.

Are there any alternatives to a total thyroidectomy?

Medication, such as carbimazole or propylthiouracil, can be used to control thyroid activityand are often used to begin with.

Radioactive iodine can also be used for some people.

It is possible to remove only part of the gland so that you continue to produce some thyroid hormones and do not need to start taking thyroxine tablets. However, your thyroid gland may become overactive or underactive in the future, and you may need further treatment.

What does the operation involve?

The operation is performed under a general anaesthetic and usually takes 90 minutes to 2 hours.

Your surgeon will make a cut on your neck in the line of one of your skin creases.

Your surgeon will remove the thyroid gland.

How can I prepare myself for the operation?

If you smoke, stopping smoking now may reduce your risk of developing complications and will improve your long-term health.

Try to maintain a healthy weight. You have a higher risk of developing complications if you are overweight. Regular exercise should help to prepare you for the operation, help you to recover and improve your long-term health. Before you start exercising, ask the healthcare team or your GP for advice.

Speak to the healthcare team about any vaccinations you might need to reduce your risk of serious illness while you recover. When you come into hospital, practise hand washing and wear a face covering when asked.
