An introduction to endocrinology and the common disorders of endocrine function and their therapy, this textbook provides an initial overview of the organization and function of the endocrine system and the feedback regulation of hormone release. Subsequent chapters deal with the endocrine secretions of each major endocrine gland, covering the mechanisms controlling hormone release, feedback regulation, principle actions of the hormones, and the clinical disorders arising due to over or under secretion of the hormones (for example, hyperthyroidism, Cushing's syndrome, and diabetes). Emphasis is placed on the diagnosis and therapeutic management of these conditions, with the possible treatments for these diseases, based on information from drug formularies and articles/reviews. Each section ends with a series of short review questions and clinical case studies which should be helpful to students when preparing for examination. Original source references are also presented for more advanced students who wish to read further.
