Experienced physicians concisely explain the pathophysiology and clinical manifestations of endocrine disorders and survey all the latest laboratory diagnostics. Topics range widely from an overview of the diagnosis of diabetes and the long-term monitoring of its complications to the evaluation of menstrual dysfunction. Coverage is also given to the diagnosis of pituitary tumors, Cushing's syndrome, thyroid disease, and hypoglycemia; the evaluation of endocrine-induced hypertension; the assessment of dyslipidemia and obesity; and approaches to diagnosing hyper- and hypocalcemia. There are also discussions of osteoporosis, hypogonadism and erectile dysfunction, and hyperandrogenism in women. The authors each review the complex physiological basis of the relevant endocrine processes and provide richly instructive recommendations for followup and long-term management of patients.
