Hyperthyroid conditions account for about 20% of thyroid disease cases. The causes of an overactive thyroid gland can be varied but the most common cause is an autoimmune condition called Graves’ disease. Complications can also occur with hyperthyroidism, including Thyroid Eye Disease, toxic diffuse goiter, hot nodules and myopathy of the muscles. Some hyperthyroid conditions can become life-threatening as well (i.e. thyroid storm).

These and other subjects related to hyperthyroidism, including symptoms, diagnosis and treatments are discussed in this 11-chapter, 6,380-word resource which could very possibly be the best ebook available on the subject of overactive thyroid conditions – hyperthyroidism!
