Hypothyroidism is a condition where the thyroid gland does not produce adequate levels of thyroid hormone. The thyroid is a butterfly-shaped gland in the front of your neck, which makes hormones that manage energy consumption in the body. When the thyroid gland does not function properly, it affects your whole body. Hypothyroidism occurs in both men and women of any age. If hypothyroidism is left untreated, it can lead to elevated cholesterol levels, and an increased risk of heart attack or stroke. In pregnant women, untreated hypothyroidism affects the baby as well, posing potential harm. Some causes of hypothyroidism are Hashimoto's thyroiditis, surgical removal of the thyroid gland, radiation treatments for cancer, viral infections and certain drugs such as lithium.
