The incidence of hemorrhoids is very high, and the recurrence rate is also high after surgical treatment or other therapies for hemorrhoids. The reason for this is that, in addition to incomplete treatment, not paying attention to the prevention of hemorrhoids is also an important factor. To prevent the occurrence of hemorrhoids, you need to pay attention to the following aspects: 1, strengthen exercise: often participate in a variety of physical activities such as radio gymnastics, taijiquan, qigong, shuttlecock, etc., can enhance the body’s ability to resist disease, reduce the possibility of disease, for hemorrhoids also have a certain preventive effect. This is because physical exercise is good for blood circulation and can harmonize the body’s qi and blood, promote gastrointestinal motility, improve pelvic congestion, prevent constipation and prevent hemorrhoids. 2, prevention of constipation: normal people defecate once a day, defecation time has a different habit of morning, noon and after dinner. Normal discharge is formed soft stool, not dry or thin, defecation does not feel difficult to defecate, there is a relaxed and comfortable feeling after the stool, which indicates good gastrointestinal function. If the stool is constipated and hard, not only is it difficult to defecate, but because of the accumulation of feces in the intestinal cavity, the pressure in the anorectal vessels is increased, and the blood flow back is impaired and the hemorrhoidal plexus is varicose to form hemorrhoids. In order to prevent constipation, the following points should be noted: 1, reasonable deployment of diet. Daily diet can be more vegetables, fruits, beans and other diets containing more vitamins and fiber, less spicy and stimulating food, such as chili, mustard, ginger and wine. 2, to develop the habit of regular bowel movements. Healthy people usually do not have feces in the rectum, with the morning wake up caused by the upright reflex, breakfast caused by the stomach, colon reflex, the colon can produce a strong “group peristalsis”, the feces pushed into the rectum, the rectum fecal accumulation to a certain amount, it will produce a bowel movement. So it’s best to get into the habit of having regular bowel movements every morning, which has an extremely important role in preventing the occurrence of hemorrhoids. Choose the correct method of treating constipation. For stubborn constipation or constipation caused by a disease, you should go to the hospital as soon as possible, do not take long-term laxatives or long-term enemas. Because long-term use of laxatives can not only make the rectal blood vessels congested and dilated, but also can lead to gastrointestinal dysfunction. 3, pay attention to the health care during pregnancy. The woman’s pregnancy can lead to increased abdominal pressure, especially in late pregnancy, the inferior vena cava is increasingly compressed by the expanding uterus, which directly affects the reflux of hemorrhoidal veins and can easily induce hemorrhoids, which is especially obvious when the fetal position is not correct. This is why you should go to the hospital regularly during pregnancy to review and correct the fetal position, which is not only good for pregnancy health, but also beneficial for preventing hemorrhoids and other anal diseases. 4, keep the area around the anus clean. The anus, rectum, and sigmoid colon are places where feces is stored and excreted, and feces contains many bacteria that can easily contaminate the area around the anus, triggering infection of the sweat and sebaceous glands around the anus, and sores and abscesses. In women, the vagina is adjacent to the anus, and vaginal secretions are more frequent, which can stimulate the anal skin and induce hemorrhoids. Therefore, you should always keep the area around the anus clean, daily warm water fumigation, change underwear, can play a role in the prevention of hemorrhoids. 5, other. Increased abdominal pressure can block hemorrhoidal venous reflux and cause hemorrhoids. There are many clinical diseases that cause increased abdominal pressure, such as abdominal tumors compressing the blood vessels in the abdominal cavity, which can obstruct the reflux of hemorrhoidal veins and cause hemorrhoids. The portal hypertension caused by hepatic sclerosis can lead to anorectal vasodilatation and cause hemorrhoids, when hepatic sclerosis should be treated first. It is not urgent to treat hemorrhoids, because hemorrhoid symptoms can be improved after hepatic steatosis is relieved.
