Hyperthyroidism: Overactivity of the Thyroid Gland
There are several causes of hyperthyroidism. Most often, the entire gland is overproducing thyroid hormone. This is called Graves' disease. Less commonly, a single nodule is responsible for the excess hormone secretion.
Your Thyroid Gland
The thyroid gland is the biggest gland in the neck. It is situated in the anterior (front) neck below the skin and muscle layers.
