Hungry stomach screaming is due to excessive fluid in the stomach, many people in the hungry stomach grumbling sound, belongs to the normal phenomenon, the main role of this sound is to prompt the body to ingest some food to supplement the body’s energy needs. When the human body is in a state of hunger, as there is no food component in the stomach, the digestive system will communicate to the brain through the nerves, and the cerebral cortex will prompt the gastric glands and intestinal glands to secrete digestive juices. Due to the stimulation of digestive juices the peristaltic speed of the intestines will also increase, but since there is no food in the digestive system, the digestive juices and gases in the intestines will emit the sound of gas over water under the peristaltic movement of the intestines, and this is when the stomach screams. If the stomach screams, you can eat some food appropriately. With the presence of food in the stomach, the digestive juices will become relatively sticky and the sound of the stomach screaming will naturally be reduced.
