There are no studies to prove the effectiveness of coffee enemas, so they are not recommended, and there is no claim that coffee enemas can treat any diseases. Enemas can be used to treat conditions such as constipation and ulcerative colitis, and they can also be used as a cleansing enema prior to intestinal surgery to avoid conditions such as infection. An enema is mainly a liquid poured into the anus, when the liquid reaches a certain amount in the body, the desire to defecate begins to appear, and the liquid poured into the body will mix with the stool in the body, thus prompting the stool to be discharged from the body. The use of coffee enemas is not recommended as there are no relevant studies to confirm the effectiveness of coffee enemas. When constipated patients are accompanied by fecal impaction and defecation obstruction, enema treatment can be carried out under the guidance of professional physicians; if there are ulcerative colitis, radiation enteritis and other diseases, enemas can also be carried out under the guidance of the doctor, usually using mesalazine enema solution; if intestinal surgery is required, enemas should also be carried out before the operation to promote fecal excretion and prevent infection during the operation. The enema treatment should be operated by medical personnel, and should not be operated by oneself to prevent damage to the mucous membrane of the anus or intestines and aggravation of the disease. During the period of enema, the main focus should be on light diet, not to eat stimulating food, to prevent irritation of the intestinal tract.
