In hypothyroidism, the thyroid gland does not produce enough hormones. This slows down the chemical reactions in the body. The body becomes mentally and physically sluggish. Hypothyroidism may also result from a complete or partial removal of the thyroid gland. As many as 15 percent of women over 60 show signs of slightly diminished thyroid function.
Hypothyroidism is the most common thyroid disorder.
It occurs in both sexes and at all ages. A person with hypothyroidism may feel lethargic and may chill easily. The skin may become dry and blemished. There may be thinning of the hair, and puffy eyes. Memory is dulled and it may be difficult to concentrate.
