Rectal polyps, also known as rectal adenomas, can be classified as either solitary or multiple. Solitary rectal polyps occur mostly in children between 2 and 8 years of age. Malignant changes rarely occur. Multiple rectal polyps mostly occur in young adults, have obvious family heredity, have a wide range of lesions, and are prone to malignant changes. Western medicine believes that the causes of rectal polyps are still unknown, generally considered to be related to the following factors: 1, dietary factors Dietary factors have a relationship with the formation of rectal polyps, especially the interaction of bacteria and bile acids, may be the basis for the formation of adenomatous polyps. 2, genetic factors It is generally believed that the formation of polyps and genetic mutations and genetic factors are closely related, from the current research shows that mutant genes can be inherited by parents to their offspring children, in the genetic opportunity is equal for men and women, there is no difference between the sexes. 3, inflammatory stimulation rectal mucosa long-term inflammatory stimulation; can cause the intestinal mucosa polyp generation, which is due to the inflammation of the intestinal mucosa, congestion and edema, erosion and ulceration after healing, resulting in the gradual contraction of the scar, the formation of polyps, and due to chronic inflammatory stimulation, resulting in glandular obstruction, mucus storage and development. 4, feces, foreign body stimulation and mechanical injury fecal sludge and foreign bodies long-term stimulation of the intestinal mucosa epithelium, as well as other causes of rectal mucosal injury, so that the cells appear abnormal proliferation, the formation of polyps. The main symptom of this disease is blood on the surface of the stool. Patients in addition to hospital treatment, diet should pay attention to the following two points: 1, with rectal polyps should not eat acid, spicy, spicy and other stimulating food.
