Hyperthyroidism occurs when the thyroid produces excess thyroid hormone. The thyroid gland is located in the neck and produces several hormones, which control metabolism, or the way cells use energy. Hyperthyroidism is a common disorder affecting over two million Americans, most of whom are women.
The most common cause of the condition is Graves' disease, which accounts for 85 percent of cases. Hyperthyroidism also can result from nodular goiter, a condition in which an inflammation of the thyroid occurs due to viral infections or other causes, ingestion of excessive amounts of thyroid hormone, and ingestion of excessive iodine.
Our Approach to Hyperthyroidism
UCSF offers comprehensive consultations and treatments for thyroid conditions, including hyperthyroidism (overactive thyroid). The best treatment for a patient with hyperthyroidism depends on the underlying cause as well as the severity of symptoms, and may include medications, radioactive iodine therapy or surgical removal of the thyroid. For patients considering surgery, UCSF offers less invasive approaches that leave either no scar or a small scar hidden under the chin.
