Cholecystokinin

Cholecystokinin (CCK) is a hormone produced by your small intestine in response to eating, especially fatty and protein-rich foods. It signals your gallbladder to release bile, assisting in fat digestion, and prompts the pancreas to secrete digestive enzymes. CCK also communicates with your brain to promote the feeling of fullness or satiety after a meal. Overall, it plays a crucial role in coordinating digestion and helping your body efficiently process nutrients from food.
