Thyroid test at Spire Parkway Hospital

Thyroid disorders affect around one in 20 people in the UK. (source: British Thyroid Foundation). Overactive thyroid (known as hyperthyroidism) is a relatively common problem when you have too much thyroid hormone in your body. It has various causes including:

• Graves' disease – an autoimmune condition that runs in the family and can happen at any age, although it is most common in women aged 20 to 40
• thyroid nodules – lumps that develop in the gland
• iodine supplements – taking too many of these can trigger the gland to produce too many hormones
• Amiodarone – a type of medication that helps you control an irregular heartbeat
• follicular thyroid cancer – in rare cases, you may develop an overactive thyroid as a result of this form of cancer.

The symptoms of an overactive thyroid include:

• hyperactivity
• mood swings – such as anxiety, irritability and nervousness
• difficulty sleeping
• fatigue
• needing to go the toilet more frequently
• unexplained or unexpected weight loss
• infrequent or light periods, or periods stopping altogether
• heavy periods
• infertility
• loss of interest in sex. (source: NHS Choices)

Underactive thyroid (known as hypothyroidism) means your thyroid gland is not producing enough hormones. It's most often caused by your immune system attacking the gland and damaging it, or from damage that happens as a result of other drug treatments. Other less common causes include a lack of dietary iodine, and sometimes you are just born with an underactive thyroid.

The symptoms include:

• tiredness
• weight gain
• depression
• constipation
• being sensitive to the cold
• dry skin and hair
• muscle aches.

Blood tests are the simplest way to test your thyroid function. They can also be used to monitor the effects of treatment.

Our patients are at the heart of what we do and we want you to be in control of your care.

All of our nurses are of the highest standard and benefit from working in our modern, well-equipped hospitals.

You will have a formal consultation with a healthcare professional. During this time you will be able to explain your medical history, symptoms and raise any concerns that you might have.

We will also discuss with you whether any further diagnostic tests, such as scans or blood tests, are needed. Any additional costs will be discussed before further tests are carried out.

We've tried to make your experience with us as easy and relaxed as possible.

The thyroid tests are relatively straightforward and painless. They involve your specialist taking a small blood sample for analysis in our laboratories.

These tests are carried out as an outpatient case so you will be able to go home straight after or as soon as you feel comfortable.

Pain relief
