When the stomach is hungry, stomach acid is secreted and the intestines peristaltically move, thus causing a gurgling sound. When the stomach is emptied of food, the body becomes hungry, and when the cerebral cortex receives a sense of hunger, it stimulates the gastric glands to secrete digestive juices, and the stomach and intestines begin to peristaltic movement. After the secretion of digestive juices, since there is no food in the stomach, when the stomach is peristaltic, the water and gas in the stomach will be confused with each other, so a gurgling sound is made. This sound can prompt the body to take in food as soon as possible to relieve the hunger. When hunger occurs, the peristalsis of the intestines will gradually accelerate, and since there is no food in the intestines, the gas in the intestines will accompany some of the digestive juices during the peristalsis and emit a gas-over-water sound, which is mainly a gurgling sound. Gurgling when hungry is a normal phenomenon, no special treatment is needed, just eat some food to relieve.
