Somatostatin is a hormone produced primarily in the pancreas and the hypothalamus. It plays a crucial role in regulating the endocrine system by inhibiting the release of several other hormones, including growth hormone and insulin. This helps maintain balance in various bodily functions, such as metabolism and growth. In addition to its role in hormone regulation, somatostatin also affects the digestive system by slowing down the process of digestion. It reduces the secretion of gastric acid and digestive enzymes, which can help control the rate at which food moves through the stomach and intestines.
