The sound of the stomach like water running i.e. active bowel sounds can be caused by drinking too much water for a short period of time, intestinal dysfunction, gastroenteritis etc. Bowel sounds are the sounds produced when the intestines move, normally 4-6 times per minute. If the number of times per minute is too high, it is called active bowel sounds, and if it is accompanied by a high pitched sound, it is called hyperactive bowel sounds. 1. Drinking too much water for a short period of time: When drinking a lot of water on an empty stomach, you will hear the sound of water flowing in the stomach, which is a normal phenomenon. After drinking a lot of water, the fluid content in the gastrointestinal tract is too high, and the sound of water flowing in the stomach will appear as soon as you exercise. 2. Intestinal dysfunction: When the body has intestinal dysfunction, the food cannot be emptied normally and will remain in the stomach. The contents of the stomach will mix with stomach acid and liquid secreted by the stomach glands, and the sound of the stomach like water running will occur. 3. Gastroenteritis: Gastroenteritis causes irritation to the intestinal smooth muscle, causing an increase in the tension of the smooth muscle, resulting in hyperactive intestinal peristalsis, in the process of peristalsis, the contents of the intestinal tract will be mixed with each other and make the sound of the stomach like a stream of water. It is recommended that the patient should go to the gastroenterology department of the regular hospital in time to find out the cause and carry out targeted treatment under the guidance of the doctor.
