Ghrelin levels are primarily stimulated by factors such as hunger, fasting, and the anticipation of food. It is produced mainly in the stomach and its release increases when the stomach is empty, signaling the body to seek food. Additionally, factors like sleep deprivation and certain hormonal changes can also influence ghrelin levels.
The phase of gastric secretion that is stimulated by the sight, taste, and smell of food is the cephalic phase. This phase involves the brain sending signals to the stomach to start producing gastric juices in anticipation of food arrival.
