Thyroid disorders are more common in women than men, and hypothyroidism (underactive thyroid) is most common in menopausal aged women. If you are suffering from unexplained weight changes, fatigue, changes in mood and difficulty sleeping it is worth checking your thyroid function.
We have two thyroid tests, Thyroid Check (£49) which measures thyroid stimulating hormone, and thyroid hormones T4 and T3 to assess how well your thyroid is functioning. Our Advanced Thyroid Check (£65) also measures thyroid antibodies to check for autoimmune conditions that affect the thyroid.
Thyroid disorders in men can cause changes in weight, energy, and mood. Symptoms of an overactive thyroid include weight loss, fatigue, irritability, and difficulty sleeping. Whereas, symptoms of an underactive thyroid include weight gain, hair loss, forgetfulness, and low mood. If you are suffering from any of these symptoms it is worth checking your thyroid function.
Want to test more? You can customise your thyroid function test at checkout to include other biomarkers from as little as £5 each. Creating a bespoke test is a great way to test exactly what you want, making it easy to manage your health.
Biomarkers that are useful to test alongside thyroid function are; HbA1c, as diabetes is associated with thyroid issues, and Cholesterol, as a thyroid disorder can affect your cholesterol levels, increasing your risk of developing heart disease.
Testing your thyroid at home is quick and easy. Your test kit includes everything you’ll need, including lancets to collect blood via a finger-prick.
It also includes instructions to help you collect your sample, but we’ve also made a video to help.
There are several symptoms associated with an underactive thyroid (hypothyroidism). Many of the symptoms are the same as other illnesses, so it’s not uncommon for an underactive thyroid to be missed. Underactive thyroid symptoms include;
Symptoms can be different depending on age too, with children experiencing slower growth, teenagers starting puberty later and the elderly suffering from depression and memory loss.
An overactive thyroid (hyperthyroidism) can cause a variety of symptoms, some of which are similar to other illnesses, making it hard to know if you have a thyroid problem. The symptoms you may suffer from include;
You may also experience phsical symptons, such as sweating, swelling of the neck and hair loss.
If you think you may be suffering from an hypothyroidism or hyperthyroidism, doing a thyroid function test is a good starting point. It will identify if you’re thyroid is producing the right amount of hormones. You can take your results to your GP if you’re concerned and need more help.
Here are some of the most frequently asked questions. If you need anything else try our help section.
Your optimum TSH, T3 and T4 levels will depend on several factors, such as your age and gender. The normal range of TSH in adults is 0.4 to 4.0 mIU/L (milli-international units per litre). The best way to know if you have optimum levels is to complete a test. You’ll get results based on you, giving you more insight into your thyroid health.
As a guide, normal thyroid levels in men and women are;
Early warning signs of thyroid problems will vary depending on whether you have an overactive or underactive thyroid. Keep a log of your symptoms, and if they match the symptoms listed above, you may have an underlying thyroid problem. We’d recommend doing a thyroid test and speaking to your GP if the results indicate an issue.
The thyroid gland is located in your neck, just in front of your windpipe. It’s shaped like a butterfly and it’s main function is to produce hormones that control your bodies metabolism.
There are a number of factors that can cause your thyroid to under or over-produce hormones. The most common reasons for thyroid problems are auto-immune diseases, such as Grave’s disease, medical treatments (such as radiation therapy) and genetics.
Thyroid conditions can be caused by autoimmune diseases where your immune system mistakenly attacks its own cells resulting in an immune response and some unpleasant symptoms.
Graves’ disease, for example, causes hyperthyroidism or an overactive thyroid. Because your immune cells attack the thyroid, it causes it to produce more thyroid hormones than your cells need and speeds up the rate at which they work. Whereas Hashimoto’s disease is an autoimmune condition that causes an underactive thyroid (hypothyroidism). It occurs when your immune system attacks the thyroid causing damage which results in not enough thyroid hormones being produced and slowing down your cells’ metabolism.
An annual check of your thyroid is usually enough to make sure it’s functioning properly. However, If you’re concerned about your thyroid function and are experiencing some of the symptoms, our thyroid tests can give you an accurate measurement of your hormone levels and help to identify potential issues.
If you have already been diagnosed with a thyroid condition, our thyroid function test can also help you to track and monitor your condition over time. You may also find this beneficial if you have implemented changes to your lifestyle to help control the condition.
