If the patient has poor intestinal tract and has constant diarrhea, it is necessary to ask whether the stool is watery or loose. If the stool is watery, consider the possibility of a recent infection, which requires a stool routine plus blood tests to clarify. If the stool is thin and more frequent every day, it is likely to be chronic colitis, functional colon disease or colon polyps, which requires an e-colonoscopy for clarification. If it is clear that it is chronic colitis, it needs to be regulated with drugs such as rectification or pefixan plus compound glutamine enteric granules for more than two weeks. If it is clear that it is functional colon disease, it needs to be treated with drugs such as Desutex plus Pefixan. If it is clear that there is a polyp in the colon, electrocoagulation and electrosurgery of the polyp should be performed under electronic colonoscopy. When you have the above symptoms, you should eat less spicy, fried and other stimulating foods, keep your abdomen warm, and not drink alcohol.
