What are the most common thyroid conditions?
The thyroid is a butterfly-shaped gland in your neck that sits just in front of your windpipe or trachea. The function of this gland is to produce hormones that regulate the body's metabolism which is your bodies function that turns food into energy. Generally, a change in the way that this gland is working can lead to producing too little or too much of the hormones that the body needs. These hormones regulate body functions such as heart rate, digestion, weight, energy levels and mood.
The most commonly associated conditions are Hypothyroidism, also known as an Underactive Thyroid and Hyperthyroidism which is an Overactive Thyroid. It can affect both men and women, however, is more prevalent in women and may be found at birth too, although this is rare. Over or underactivity of the thyroid gland causes the pituitary gland to respond as it measures the hormone output from the thyroid gland.
Another condition associated with the thyroid gland is Thyroid Cancer but we will not look at that within this article. If you would like to read more about how cancer affects a life insurance application, you can read more about it in our article 'Can I get life insurance if I've had Cancer?'

- Graves Disease is a condition that can cause an overactive thyroid and 3 out of 4 people who suffer with Graves Disease experience an overactive thyroid.
- An overactive thyroid can also be caused by lumps or nodules on the gland that produce excess hormones.
- Medication that is used to treat some heart irregularities may also cause the thyroid gland to become overactive.
What causes an underactive thyroid?
- Hashimoto's Disease is a known cause of an underactive thyroid and is referred to as Hashimoto's Thyroiditis. It's often linked to inherited conditions and is sometimes observed alongside other autoimmune illnesses like Type I Diabetes or Vitiligo.
- The treatment used for an overactive thyroid or thyroid cancer can also cause an underactive thyroid by inhibiting too much hormone production.
- There are other less common causes of an underactive thyroid including congenital hypothyroidism, viral infections or it can be caused by medications being taken for other reasons.

When applying for life, critical illness or sick pay insurance, you'll be asked for the following details:
- Date of diagnosis
- Your symptoms, past and present
- Treatment and medication, past and present
- Any other conditions related to your thyroid condition
- How the condition affects your daily life, if at all
- Any time you had to take off work due to your condition
- Any planned surgery
- Your most recent results showing your Thyroid-Stimulating Hormone (TSH) levels (if you don't have these, the insurer will request this information from your doctor)
Will a life insurance company write to my doctor about my thyroid condition?
Providing as much information as you can to the insurer will help avoid requests to your GP surgery and in turn the delays that this can cause to your application. In some cases, the insurer may still have to write to your GP to access more detailed information about your health than you are able to provide. If you're at all unsure about any of your health information, you should simply request that the insurer writes to your GP for clarification. Remember that any claim against the policy will be checked and the information on your application must match your health records to ensure the claim is paid.
