Colon hydrotherapy refers to a treatment and health care method that involves the cleansing and irrigation of the entire colon by injecting purified warm water into the colon through the anus with a special device. In recent years, colon hydrotherapy has become popular worldwide, and hydrotherapy equipment is gradually entering hospitals and clinics. How to master the indications of colon hydrotherapy and the correct use of colon hydrotherapy is a problem in front of the majority of patients and medical personnel. As we all know, the intestine is responsible for the excretion of dregs and absorption of water. Food residues are absorbed by the mucous membrane of the large intestine, and fermentation and spoilage by bacteria turn into feces. In addition to food residues, feces also includes shed intestinal epithelial cells and a large number of bacteria. As a large number of bacteria and their decomposition metabolites, as well as a large number of harmful substances exist in the feces, if they are not discharged on time, some of them can be absorbed through the colonic mucosa and enter other internal organs through the portal system, thus causing physical diseases. Therefore, the main effect of colon hydrotherapy is to assist the body to excrete feces and harmful substances in the colon in a timely and more complete manner. Therefore, constipation is one of the most important indications for colon hydrotherapy. The treatment of constipation by colon hydrotherapy is mainly reflected in the following aspects: 1, to assist patients in the timely excretion of feces, through repeated injection of water into the intestinal cavity, drainage, and appropriate abdominal massage, so that the feces out of the body in a timely manner. 2, complete removal of the intestinal cavity stagnant stool, some of the intestinal cavity stagnant stool, hidden in the mucosal wall of the large intestine, generally difficult to expel, colon hydrotherapy is repeatedly, a long time (more than 45 minutes) water injection and drainage, and a certain pressure, and constantly clean the intestine, so that it can be expelled. 3.Softening the dry and hard stools in the intestinal cavity.

If drugs are added to the process of colon hydrotherapy, it can not only cleanse the intestines and eliminate feces, but also play a therapeutic role of drugs, by using different laxative drugs, thus treating constipation caused by various reasons. Colon hydrotherapy has a certain effect on the relief of constipation, but you should not rely on it for a long time, and you should not do it frequently, because excessive frequency will lead to an imbalance in the intestinal flora, which will destroy the function of the intestinal tract.
