Gastric inhibitory peptide (GIP) is a hormone produced in the small intestine, specifically in the duodenum. It plays a crucial role in the digestive process by inhibiting gastric motility, which slows down the emptying of food from the stomach. This allows for better nutrient absorption in the intestines. In addition to its role in digestion, GIP also stimulates the release of insulin from the pancreas in response to food intake. This helps regulate blood sugar levels, making GIP an important factor in maintaining metabolic health and managing conditions like diabetes.
