Question

Which hormone cause the sensation of hunger?

Answer 1

Answer:

Ghrelin /ˈɡrɛlɪn/ is a circulating hormone produced by enteroendocrine cells of the gastrointestinal tract, especially the stomach,[5][6] and is often called a "hunger hormone" because it increases food intake.[6] Blood levels of ghrelin are highest before meals when hungry, returning to lower levels after mealtimes.[6][7] Ghrelin may help prepare for food intake[6][8] by increasing gastric motility and gastric acid secretion.[
