The cause of stomach rumbling may be a normal physiological phenomenon, or it may be caused by indigestion, acute enteritis, intestinal flora imbalance, gastrointestinal neurosis, and so on. 1. Normal physiology: if eating irregularly, often in the hungry time has not eaten, the stomach will make grumbling. 2. Indigestion: Due to weak digestion, food ferments in the stomach and produces a large amount of gas, which collects in the intestines after being expelled, and thus may also cause gurgling in the stomach. 3. Acute intestinal inflammation: because of inflammation in the intestines, it will lead to accelerated intestinal peristalsis, causing diarrhea, abdominal distension, and the gas will stimulate the smooth muscle of the intestines, which will result in gurgling in the stomach. 4. Intestinal flora imbalance: due to intestinal flora imbalance, harmful bacteria multiply, which can also lead to intestinal dysfunction, causing stomach gurgling, accompanied by an increase in the number of bowel movements. 5. Gastrointestinal neurosis: due to excessive stress and anxiety can lead to gastrointestinal dysfunction, which can also cause stomach gurgling. If the gurgling continues without relief, you need to go to the hospital in time, under the guidance of the doctor to carry out the appropriate treatment, to avoid delays in the condition.
