Mucus in the stool may be caused by dietary factors on the one hand, and may also be a symptom caused by chronic enteritis. Normal stools contain a small amount of mucus, which is generally not easy to detect when mixed with stools. If there is a large amount of mucus in the stool, it suggests increased secretion of intestinal fluid. If there are no uncomfortable symptoms, it may be due to dietary changes, and generally does not require special treatment. If accompanied by abdominal pain, abdominal distension, bowel movement after the feeling of urgency and heaviness, we should consider whether the symptoms are caused by chronic enteritis. Need to further check the stool routine and colonoscopy, to clarify the specific cause of lesions and lesion sites, further targeted treatment. Normally, we should also pay attention to light diet, avoid cold, greasy, spicy, stimulating food.
