Around 10% of the British adult population – both men and women – suffer symptoms caused by an underactive thyroid gland, commonly known as hypothyroidism. Conversely, some people have an overactive thyroid gland, called hyperthyroidism.
The thyroid hormones essentially control the metabolic rate of all cells throughout the body. This means that it influences our weight, but is an oversimplification of the overall role of the thyroid within the body.
Metabolism literally means “tissue change”, and therefore includes all the physical and chemical processes by which the living body is maintained, as well as those that produce and make energy for various forms of work.
In other words, the thyroid influences every system, organ and muscle in the body. Problems with the thyroid gland can therefore be the cause of many recurring illnesses and chronic conditions.
