This book is also included as a section in "The Everything Thyroid Disease Book!", so this version is for those who are interested in the subject of hyperthyroidism specifically (also available in eBook). 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 resource. NOTE: This book is approximately 6,539 words in length. The "Best Darn" reference in the title, is not to imply that this is an extensive medical journal but rather that the book contains all aspects of information on the subject that most laypersons would be seeking.
