peptide YY

Peptide YY (PYY) is a hormone produced in the digestive system, mainly in the small intestine and colon, in response to eating. It helps regulate appetite by signaling to the brain that you're full, reducing hunger and slowing down gut activity to aid digestion. PYY levels increase after meals, especially those rich in protein and fat, which promotes feelings of satiety. This hormone plays a role in maintaining energy balance and weight management by limiting food intake. Understanding PYY's function can help in exploring treatments for obesity and metabolic disorders.
