It can be cleared through the use of diarrhea-conducting drugs such as lactulose, enema and other methods to expel all things from the intestines. 1. Diarrhea-inducing medication: The application of osmotic laxatives, such as polyethylene glycol, lactulose, etc., is usually recommended for bowel cleansing. By increasing the osmotic pressure in the intestines, it promotes the secretion of water from the intestinal mucosa into the intestinal lumen to lubricate the intestinal lumen and soften the feces, which then achieves the purpose of diarrhea-inducing bowel cleansing. 2. Enema: Enema saline is injected into the intestinal cavity through the anus to promote the discharge of intestinal contents, but repeated operation may damage the intestinal mucosa. The above drugs are prohibited for those who are allergic to them and should be taken in accordance with medical advice. If the effect of bowel cleansing is not good, it is recommended to go to the regular hospital in a timely manner, after clarifying the cause of the disease, under the guidance of the doctor for targeted treatment.
