Causes of Hyperthyroidism Hyperthyroidism can be caused by a number of things: Toxic nodule - A single nodule or lump in the thyroid can produce more thyroid hormone than the body needs and lead to hyperthyroidism. Toxic multinodular goiter - If the thyroid gland has several nodules, those nodules can sometimes produce too much thyroid hormone causing hyperthyroidism.
This is most often found in patients over 50 years old. In many cases, a person may have had a multinodular goiter for several years before it starts to produce excess amounts of thyroid hormone. Graves' disease - Graves' disease is an autoimmune disorder in which the body's immune system attacks the thyroid.
In some patients, the eyes may be affected. Patients may notice the eyes become more prominent, the eyelids do not close properly, a gritty sensation and general irritation of the eyes, increased tear production, or double vision. Like other autoimmune diseases, this condition may occur in other family members and is much more common in women than in men. Sub-acute thyroiditis - This type of hyperthyroidism can follow a viral infection which causes inflammation of the thyroid gland.
This inflammation causes the thyroid to release excess amounts of thyroid hormone into the blood stream which leads to hyperthyroidism. Over time the thyroid usually returns to its normal state.
