Endocrinology

Endocrinology is a division of medicine dealing with regulation of body functions by hormones and other biochemical and treatment of endocrine system imbalances. Endocrine treatment is based on replacing deficient hormones with purified extracts. Nuclear technology has led to new treatments; use of radioactive iodine for hyperthyroidism greatly abridged the need for thyroid gland surgery. The finding of minute amounts of hormone with radioimmunoassay permits early diagnosis and treatment of endocrine sickness.
