What is PYY?

Peptide YY (PYY) is a 36-amino acid peptide hormone secreted by L-cells in the ileum and colon in response to food consumption, particularly fats and proteins. It acts as a key regulator of appetite by binding to Y2 receptors in the hypothalamus, inducing satiety and reducing food intake. In the Indian context, PYY has gained attention due to rising rates of obesity, type 2 diabetes, and metabolic syndrome. Researchers study how traditional Indian diets—rich in spices, fiber, and plant-based proteins—influence PYY secretion compared to Western diets. In clinical practice, PYY levels are measured to assess gastrointestinal disorders like dumping syndrome or to evaluate appetite control in bariatric surgery patients. It is also used in pharmacological studies aiming to develop anti-obesity drugs. For students, PYY is a core topic in physiology and biochemistry for NEET PG, AIIMS, and nursing exams. Understanding its mechanism helps in grasping the broader endocrine regulation of energy balance. The hormone was first isolated in 1980 and continues to be a focus of metabolic research globally, including at Indian institutions like AIIMS and CCMB.

Example

After a heavy meal, the gut releases Peptide YY to signal the brain that enough food has been consumed, curbing further appetite.

PYY — frequently asked questions

What is the full form of PYY?
The full form of PYY is Peptide YY, a hormone that signals satiety to the brain after eating.
What is the role of PYY in the body?
PYY reduces appetite by binding to receptors in the hypothalamus, slowing gastric emptying, and promoting a feeling of fullness.
How is PYY relevant to obesity treatment in India?
Low PYY levels are linked to overeating; Indian research focuses on dietary patterns that naturally boost PYY to help manage obesity and diabetes.
