Typical symptoms include abdominal pain, diarrhea, and constipation in some patients. 2. Chronic colitis: the direct cause of the disease is not clear, it may be related to genetics, intestinal immune dysfunction, improper diet, mental and psychological tension and other factors. Patients will experience symptoms such as frequent stomach pain and frequent bowel movements. Stools tend to have increased mucus and can also be accompanied by pus and blood. 3.
