Hypothyroidism

I am very grateful to have the opportunity to raise this subject in Parliament. It was first brought to my attention by a constituent; I will obviously keep her name confidential, but she is content for me to discuss her experiences, which are not unusual. Hypothyroidism is not a small or niche illness; it is estimated that up to 3.5 million people in the UK may have a thyroid problem. It disproportionately affects women compared with men, by a power of 10, and the effects of the disease can be really debilitating, with the many symptoms including tiredness, aches, weight change, coldness, memory loss and depression. Even more seriously, the disease can impact on the functioning of the heart. The problem is that many of these symptoms are not unique indicators, and therefore they may be hard to pinpoint or describe.

When someone is suspected of having an underactive thyroid, or hypothyroidism as it is known, their GP will usually do a blood test to check the levels of the thyroid-stimulating hormone, or TSH. This test is called the TSH or FT4 test. In the UK, an abnormal test result will only come back for someone who is above the “over” levels of the TSH bell curve for the population. That means that some people may have sub-clinical levels of hypothyroidism but they are not flagged up for treatment. Once again, there is a disparity between the number of men and women with sub-clinical levels of hypothyroidism; three times as many women as men suffer from those sub-clinical levels. The opposite can also be true. Doctors have to consider how to treat patients with abnormal results who otherwise show no clinical signs of hypothyroidism. Therefore, it is accepted that GPs might face many different problems when trying to treat a patient with hypothyroidism.

However, my constituents know exactly how difficult and frustrating it can be to live without effective treatment of their condition. I expect that all of us know someone who has suffered from hypothyroidism, and I think that we are all aware of the impact it can have on someone’s quality of life.
