Watery stools may be related to functional dyspepsia, cold abdomen, intestinal bacterial infection, viral infection and intestinal cancer. 1. Functional dyspepsia: the food in the stomach is not fully digested before it is discharged into the intestines, which stimulates the peristalsis of the intestines to increase, resulting in watery stools, which may be accompanied by food residues. 2. Abdominal cold: can lead to intestinal peristalsis faster, the water in the feces can not be absorbed in time, and then appear watery stools. 3. Intestinal bacterial infections: such as Escherichia coli, Salmonella, staphylococcus, etc., which can invade the intestinal mucosa and release toxins, leading to an increase in mucus secreted by the intestinal mucosa, and affecting the intestinal mucosa in absorbing water, thus causing watery stools. 4. Intestinal viral infections: such as rotavirus, enteric adenovirus and other infections, which can be manifested as watery stools. 5. Bowel cancer: invasion of intestinal tissues by cancer cells can cause watery stools, bloody stools, body wasting, anemia and other symptoms. There are many other reasons leading to watery stools, so it is recommended to go to regular hospitals in time for consultation, after clarifying the cause of the disease, and then carry out targeted treatment under the guidance of doctors.
