Not sure if you might have an underactive thyroid? We've got the fast facts you need to know.

What is an underactive thyroid?

Also called hypothyroidism, the thyroid gland which is in the front of the neck produces hormones that keep your metabolism running properly.

With hypothyroidism, the gland doesn't produce enough hormones and the body refuses to work properly. It's not to be confused with hyperthyroidism which is where the thyroid gland produces too much hormone.

What are the symptoms of an underactive thyroid?

Typical things to watch out for with hypothyroidism are:

Weight gain
Tiredness
Muscle cramps
Dry, scaly, cold skin
A hoarse voice
Slow heart rate

What causes hypothyroidism?

There are three main causes:

An autoimmune inflammation of the thyroid gland, known as thyroiditis
As a result of treatment for an overactive thyroid
Your genes: You inherit an under-developed thyroid gland

Occasionally, some people get it by taking large amounts of iodine in cough syrups or dietary supplements

When will I get hypothyroidism?

An underactive thyroid can be present from birth, but it's most common in adults, especially women, from middle age onwards.

How do I know if I've got an underactive thyroid?

Your doctor will have to carry out blood tests and check out well your thyroid gland is working.

How is hypothyroidism treated?

You'll need to take tablets called thyroxine which should correct the working of the thyroid gland.

How long will the hypothyroidism last?

Once diagnosed it's here to stay, but the hormone tablets have almost no side effects and, with proper treatment, you will be able to lead a completely normal life.

Will I have to keep going back to the doctor?

Once the correct dose of thyroxine for you has been reached, you'll only need your metabolic rate checked once a year.
