Hemorrhoids, or hemorrhoids, are soft venous masses formed by the dilation and flexion of the venous plexus under the mucous membrane at the end of the human rectum and under the skin of the anal canal, called hemorrhoids, also known as hemorrhoids, hemorrhoids, hemorrhoid disease, hemorrhoid disease, etc. Hemorrhoids include internal hemorrhoids, external hemorrhoids, and mixed hemorrhoids, and are a chronic disease in which one or more soft venous masses form as a result of varicosities in the venous plexus at the base of the anorectum and the anal mucosa. So what are the causes of hemorrhoids? 1, bad bowel habits When going to the toilet squatting position to read a book and newspaper, resulting in squatting and prolonged bowel time, easy to cause stasis of blood in the anorectal appendix and cause disease. Smoking when going to the toilet can buffer the brain’s stool reflex, 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 violently 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 abnormalities diarrhea and constipation are important causes of hemorrhoids. The biggest culprit is constipation, the 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 fecal masses will certainly put the anus under greater pressure, resulting in a series of pathological changes such as stasis, swelling and fissures. Diarrhea is often a medical manifestation of colon disease, and diarrhea can also increase the chances of localized 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 the 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 in the lower part of the body, hemorrhoidal venous reflux is not smooth. 4, dietary reasons It is natural that the dietary pattern or diet variety inevitably changes in daily life. Such as the quality of food coarse, changes in the type 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. People who drink alcohol for a long time or like to eat spicy food, because wine and spicy substances can stimulate the mucous membrane of the digestive tract, resulting in vasodilation, colon dysfunction, the rate of anorectal disease increased significantly.
