Hemorrhoids have now become a more common disease of modern people, and the eight causes of hemorrhoids are: 1, bad bowel habits: squatting position when reading a newspaper, resulting in squatting and prolonged bowel time, easily caused by stasis of blood in the anal appendix and cause disease. Smoking can buffer the brain’s stool reflex when going to the toilet, it is easy to cause constipation. Excessive force during the bowel movement, some people regardless of whether the bowel feeling is strong, blindly and constantly fierce struggle, can only make the appendix anus and pelvic floor muscles increase unnecessary burden and local stasis, resulting in the occurrence and spread of disease. 2, stool abnormal: diarrhea and constipation are important causes of hemorrhoids. The biggest bane is constipation, long-term retention of toxic substances in the appendix can not only lead to appendix cancer, and the accumulation of feces, affecting blood circulation. The effort to relieve dry feces will certainly put the anus under greater pressure, resulting in a series of pathological changes such as stasis, swelling and fissures. Diarrhea is often the medical embodiment of colon disease, and diarrhea can also increase the chances of local anal infection and the occurrence of anal sinusitis, inflammatory external hemorrhoids, perianal abscesses and other diseases. 3, chronic diseases: such as long-term poor nutrition, weakness, resulting in the anal sphincter relaxation and weakness. Long-term chronic bronchitis, emphysema, rising abdominal pressure caused by coughing and wheezing, and pelvic stasis. Chronic hepatitis, hepatic steatosis, diarrhea, colitis, etc. are all triggers for the occurrence of anal diseases. Therefore, in prevention and treatment, we should pay attention to the patient’s systemic status and adopt reasonable and effective preventive and curative measures. Occupational causes: prolonged standing or prolonged sitting. Because of the upright or sitting position, the anal appendix resides in the lower part of the body, and the hemorrhoidal vein does not reflux well. 4, dietary reasons: it is natural that dietary patterns or diet varieties inevitably change in daily life. Such as the quality of food coarse, changes in the variety of vegetables and the amount of increase or decrease, the amount of protein, fat, starch, fiber and other content, water intake situation, can directly affect the stool composition, resulting in anal appendix disease. Long-term alcohol or spicy food, because wine and spicy substances can stimulate the mucosa of the digestive tract, resulting in vasodilatation, colon dysfunction, the incidence of anorectal disease increased significantly. 5, physiological reasons: colon, cecum for the transport of food residues, the main organ for the retention of feces, and food by the body after decomposition and absorption, residues often with a large number of harmful substances, long-term retention in the colon cecum, can lead to tumors. — Patients with hemorrhoids should pay attention to self-regulation. 6, anatomical reasons: the anus cecum has a large number of special structures, such as the anal crypt, anal glands, anal papillae, cecum flaps and special vascular structures. The lack of venous valves in the cecum veins makes the blood easy to stagnate. The portal vein system and the vena cava system are in the lower end of the cecum, with many venous plexuses and anastomotic branches, weak vein walls and reduced resistance to pressure, and loose submucosal tissue of the cecum, which is conducive to the expansion of varicose deformation of veins and easy formation of hemorrhoids. 7, embryonic development abnormal reasons: the anus cecum is the human body in the embryonic development process of endoderm and ectoderm fusion each other, such as abnormal development process, can occur in the anus cecum many congenital anorectal diseases, such as congenital anus, congenital cecum vaginal fistula, congenital giant colon, etc. 8, genetic reasons: due to genetic gene defects, multiple colon polyps, p-j syndrome and other genetic anorectal diseases can occur.
