Endocrinology is the study of hormones and the physiology and pathophysiology of the endocrine system, including glandular and metabolic systems. Clinical Endocrinology is concerned with the diagnosis and management of endocrine disorders, including disorders of the thyroid and hypothalamus, adrenal glands, production of hormones, or metabolism of lipids, osteoporosis, diabetes, pituitary disease, and reproductive issues. There is a large spectrum of endocrine disorders, which are often genetic, congenital, or long-term, and affect multiple body systems. Diagnosis is often complex and can involve physical exams, interpretation of laboratory and biochemical tests, organ imaging and nuclear medicine. Specialist expertise and procedural skills are required for the management and treatment of patients, which involves a range of therapies, pharmacology and care provided by a multidisciplinary team. This field of medicine involves collaboration between specialists in metabolic disease, clinical biochemistry, renal medicine, neurology, cardiovascular disease, genetics, and chronic disease management
