Cholecystokinin (CCK) is a digestive hormone released with secretin when food from the
stomach moves to the duodenum. Cholecystokinin improves digestion and functions
as a hunger suppressant by activating the satiety center of the hypothalamus in
the brain. If cholecystokinin were not released after eating a fatty meal, the
person will not feel full and may eat more fat than what the body requires. This
can result in health problems.
