The high number of stools per day may be caused by irritable bowel syndrome, intestinal flora imbalance, enteritis, intestinal tumors and other reasons. 1. Irritable Bowel Syndrome (IBS): stress, anxiety and pressure can trigger IBS, which can increase the number of bowel movements per day. 2. Intestinal flora imbalance: more harmful bacteria in the intestinal tract can cause an increase in the number of stools per day, increased gas and other symptoms. 3. Intestinal inflammation: such as bacterial dysentery, rotavirus infection, ulcerative colitis, etc., which can cause changes in the character of the stool, manifested as drainage-like stool, mucus stool, and increased frequency of defecation and other symptoms. 4. Intestinal tumors: for example, colon cancer, rectal cancer, manifested by increased frequency of bowel movements, mucus blood stools, emaciation and other symptoms. If the number of bowel movements increases every day, it is recommended to consult a doctor in time to find out the cause of the disease and follow the doctor’s instructions.
