Somatostatin, also known as growth hormone-inhibiting hormone (GHIH), is a peptide hormone produced by the delta cells of the pancreatic islets, the hypothalamus, and various cells in the gastrointestinal tract. It acts as a powerful, universal inhibitor. It inhibits the release of growth hormone (GH) and thyroid-stimulating hormone (TSH) from the anterior pituitary. In the pancreas, it inhibits the secretion of both insulin and glucagon. In the gut, it inhibits the release of gastrin, secretin, and other GI hormones, slowing down digestion and absorption.
