The two main types of thyroid dysfunction are either overproduction of thyroid hormone or underproduction of thyroid hormone. The most common cause of overproduction of thyroid hormone is called Graves Disease and the most common cause of underproduction of thyroid hormone is called Hashimoto’s Disease. Both of these common problems are caused by an underlying autoimmune process in the thyroid. It is important to evaluate thyroid function closely to determine the cause of the problem and choose the right type of treatment to balance the thyroid hormones.
