The hormone cholecystokinin (CCK) increases the sensitivity of stretch receptors in the stomach and helps signal feelings of fullness while eating a meal. Epinephrine and neuropeptide Y (NPY) are involved in regulating appetite, but they do not directly affect stretch receptors in the stomach. Ghrelin is a hormone that stimulates appetite, so it would not increase feelings of fullness while eating a meal.
