About Underactive Thyroid (Hypothyroidism)

An underactive thyroid is one of the most common medical conditions affecting up to 1 in 12 people - yet it often remains undiagnosed as it is difficult to identify without a test and by symptoms alone.

Thyroid disorders are one of the most common medical conditions, particularly in women. An underactive thyroid is 10 times more common in women than in men, and up to 2% of the UK adult population suffers from the condition. The incidence increases with age and up to 8% of women over 50 and men over 65 have an underactive thyroid.

The thyroid gland makes the hormone thyroxine that is responsible for regulating your body's metabolism and is needed for your body to work normally. If too little thyroxine is produced your metabolism slows down, giving rise to the condition called hypothyroidism or underactive thyroid. Low levels of thyroxine result in a slowing down of the mental and physical processes of the whole body, giving rise to a wide range of symptoms that include;

  • general tiredness
  • weight increase 
  • brittle, dry and thinning hair
  • dry and coarse skin 
  • heavier and longer periods
  • constipation
  • memory problems and difficulty concentrating 
  • depression
  • muscular weakness

The symptoms of an underactive thyroid are often develop very slowly, are general in nature and vary widely from one person to the next. This makes the condition difficult to identify by symptoms alone and it often goes undiagnosed without a suitable blood test. A test for raised TSH (Thyroid Stimulating Hormone) levels, which is measured in our ThyroScreen Test, is regarded as the most important and sensitive test for underactive thyroid.

If you are concerned that you may have an underactive thyroid you can easily test yourself at home with our ThyroScreen Test Kit. This easy to use and reliable test will show if you have a raised TSH level in just 10 minutes.

The most common cause of low thyroid function is autoimmune thyroiditis (Hashimoto's thyroiditis), a self-destructive process in which the body's immune system attackes the cells of the thyroid gland as though they were foreign cells. Other causes include too little iodine in your diet, the side effects of a treatment or surgery for hyperthyroidism or thyroid cancer, and a side effect of eating an excess of some health foods such as kelp (seaweed).
