Does pituitary gland affect blood sugar?

Pituitary hormones play an integral role in controlling glucose metabolism. There are diseases like acromegaly and Cushing’s disease which are overtly associated with diabetes. Emerging evidence suggests that prolactin, vasopressin and oxytocin also exert a subtle physiological role in glucose homeostasis.

Why does pheochromocytoma cause hyperglycemia?

Catecholamines have been shown to directly suppress insulin secretion from the pancreas and induce glycogenolysis in the liver via α-adrenergic receptor stimulation, leading to hyperglycemia (6). Catecholamine excess as a secondary cause of diabetes mellitus should be considered in patients with pheochromocytoma.

What happens if a pituitary tumor goes untreated?
