The patient has the same problem of defecation. If it happens in recent days and has symptoms such as fever and abdominal pain, it is likely to be acute gastroenteritis. It is necessary to test stool routine and blood routine to make it clear. First of all, if the onset time is about one week to two months, functional diarrhea or functional colon disease is likely to be considered, which is directly related to intestinal flora imbalance and intestinal peristalsis dysfunction. Electronic colonoscopy can be used to make it clear. After the diagnosis, it needs to be treated with drugs such as deshute and enteric-coated granules. Secondly, if the onset time is more than two months, it often shows loose stool in the morning. It is probably chronic colitis or colonic polyps, which need to be confirmed by electronic colonoscopy. Chronic colitis needs to be treated with drugs such as enteric-coated granules such as enteric-coated granules or bifico and compound glutamine. Thirdly, if it is colonic polyps, it needs electrocoagulation and electrocision under colonoscopy.
