Loud intestinal peristalsis is caused by gastrointestinal dysfunction, indigestion, enteritis and other factors. The intestinal system mainly transports and excretes food through peristalsis, and under normal circumstances only a very slight sound can not be heard, but when there is too much water and liquid gathered in the intestines, the intestines in the process of peristalsis, liquid and water will be accompanied by peristalsis and rattling, and then there will be intestinal hyperacute sound, and the sound of intestinal peristalsis can even be heard with the naked ear. When gastrointestinal dysfunction, the absorption of nutrients, water and gas by the intestinal wall is affected, so the water and gas content in the food residue is high, resulting in hyperactive bowel sounds. In case of indigestion, food in a semi-digested state causes irritation to the intestines, and the intestines are not able to absorb the nutrients from the food in its entirety, hence the hyperactive bowel sounds. Inflammation of the intestinal mucosa during an attack of enteritis results in increased peristalsis, which can also be accompanied by hyperactive bowel sounds.
