About Thyroid Dsyfunction
Thyroid dysfunction is often caused by low hormone levels, also referred to as hypothyroidism (or underactive thyroid). Hashimoto’s disease, is an autoimmune disorder that can lead to hypothyroidism. In Hashimoto’s, your immune system produces antibodies that attack and destroy the hormone producing cells in your thyroid gland.
There are two main causes for thyroid under activity (hypothyroidism) in the UK:
-Autoimmune Thyroid Disease (Hashimoto’s)
-A side effect of treatment for an over active thyroid or thyroid cancer
It is important to recognise that some people may test negative for hypothyroidism on a standard blood test (which usually tests TSH and T4 hormones), and still exhibit typical symptoms of low thyroid hormones, this is known as subclinical hypothyroidism. For more in-depth evaluation of thyroid health, testing must include a more comprehensive range of markers (also including the most active thyroid hormone T3) in conjunction with clinical assessment.
Symptoms of Hypothyroidism
Usual symptoms of an underactive thyroid, that can sometimes be very similar to those of Perimenopause include:
- Weight gain
- Poor temperature control / feeling cold
- Thinning, dry hair
- Brittle nails
- Low mood
