Endocrinologists help detect, treat, prevent and manage disorders of the endocrine glands - adrenals, pancreas, pituitary, parathyroid, thyroid, ovaries, and testis - and their associated hormones. Diabetologists are endocrinologists who specialise and focus on treating conditions caused by insulin secretion. They typically treat patients with diabetes mellitus or complications associated with diabetes, including Type I diabetes and gestational diabetes.
