Colorectal polyp risk factors (1) dietary factors: dietary factors and colorectal polyps to form a certain relationship. Especially the interaction between bacteria and bile. Adenomatous interest may be within the formation.
Risk factors of colorectal polyps (2) genetic factors: general view, polyp formation and gene mutation and genetic factors closely related to the situation from the current study showed that. Mutated gene to their offspring by their parents to their children, men and women in the genetic probability is equal, no gender differences.
Risk factors of colorectal polyps (3) inflammatory stimulation: Rectal mucosal inflammation has long been stimulated, can cause the formation of intestinal polyps, which is due to inflammation of the intestinal mucosa congestion and edema, erosion, ulcers, healing after. Led to the gradual contraction of scar. Formed polyps due to chronic inflammation is also stimulated, causing the gland obstruction, mucus retention and disease.
Risk factors of colorectal polyps (4) manure and mechanical injury stimulate foreign body: fecal residue and foreign long-term stimulation of crude intestinal mucosa, and other causes of rectal mucosal damage, abnormal proliferation of the cells, the formation of polyps.
Different areas, the incidence of polyps is also different, such as North America, Western Europe, more common, less in South Asia. High-fat, low fiber intake were due to cancer-causing substances stay in the small intestine, the high incidence of polyps. Large quantities of beer, smoking, poor immune function in rabbits with atherosclerosis, or hardening, as well as the incidence of polyps in patients with coronary heart disease increased in patients after cholecystectomy, due to changes in bile flow and discharge time, and surgery After the change of intestinal flora, thus changing the metabolism of bile salts and bile acids, bile acid content of the large intestine increased the role of high concentrations of bile acids in the intestinal mucosa, the polyps and colorectal cancer rates higher, but persistent Physical activity can reduce the large intestine (especially the right colon> new organisms occurred. because exercise increases the excitability of the vagus nerve, strengthen the end peristalsis, so that carcinogenic substances reduce the role of the intestinal mucosa.
