Thyrotoxicosis, not hyperthyroidism, is a frequent sequelae of parathyroidectomy

Thyrotoxicosis following parathyroidectomy is a common phenomenon, yet it is frequently unrecognized and underappreciated and often inaccurately referred to as hyperthyroidism. Hyperthyroidism is a syndrome that occurs from excess synthesis and secretion of thyroid hormone from the thyroid gland. It is distinct from thyrotoxicosis, in which excess thyroid hormone may also occur from thyroid hormone released from the thyroid gland or from sources other than the thyroid gland. This is an important distinction because thioamide drugs are not effective for treatment of thyrotoxicosis that occurs as a result of release of thyroid hormone; rather it is principally treated with a beta-blocker.
