Hemorrhoids are the most common anorectal disease, and I often encounter patients in the clinic who ask, “Why do I have hemorrhoids?” Although recent anatomical discoveries have given a new understanding of the modern concept of hemorrhoids, their etiology is still not fully understood and is now thought to be related to difficult bowel movements, diarrhea, low dietary fiber, pregnancy, dysfunction of the internal anal sphincter, genetics, age, anatomy, etc. There are many triggers for hemorrhoids, of which constipation, chronic alcohol consumption, eating large amounts of irritating food and being sedentary are the main ones. If you don’t pay attention to these, you may be a person with hemorrhoids in the near future, so how to prevent them? 1, physical exercise. You can do some physical and mental health activities in your daily life, such as walking, Tai Chi, etc. 2, prevention of constipation. Constipation is the most common and most important cause of hemorrhoids. In daily life, pay attention to a light diet, drink more water, eat more fiber-rich vegetables and fruits, avoid drinking alcohol, eating too fine, and try to reduce the consumption of food that is not easy to digest or easy to trigger constipation; if you already suffer from constipation, choose the right treatment according to your situation. Eat less spicy and stimulating food, such as chili, garlic, onion, mustard, etc. 3, develop the habit of regular bowel movements. Correct the bad defecation habits: not to defecate when you have the intention, squatting for too long when defecating, or reading newspapers, or excessive force, etc. The “upright reflex” is caused in the morning after a healthy person wakes up, and the “gastrocolic reflex” is caused after eating breakfast, which can produce the intention to defecate, so it is best to develop the habit of defecating regularly every morning, which has a very important role in preventing the occurrence of hemorrhoids. 4, keep the area around the anus clean. The area around the anus is susceptible to contamination by these bacteria, which can lead to infection of the sweat glands and sebaceous glands around the anus, resulting in boils and abscesses. The vagina of women is adjacent to the anus, and vaginal secretions can stimulate the anal skin and induce hemorrhoids. The actual fact is that you should always keep the area around your anus clean, wash it in time, and change your underwear regularly. 5, avoid sitting and standing for a long time. When a person is standing or sitting, the anorectum is located in the lower part, due to gravity and organ compression, resulting in slow venous reflux and abdominal organ congestion, causing excessive filling of the hemorrhoid veins, a decrease in venous wall tension, and easy stasis and expansion of blood vessels. It is best to avoid being sedentary for more than 2 hours and change your position in time. 6, pay attention to maternal health care. After pregnancy, the abdominal pressure increases, the inferior vena cava is compressed by the enlarged uterus, which directly affects the reflux of hemorrhoidal veins, coupled with the low activity during pregnancy, the gastrointestinal function is weakened, the fecal cavity stays longer, the stool is dry and difficult to discharge, which induces hemorrhoid disease. You should be properly active during pregnancy, do a good job of health care measures, keep the bowels open, fumigate the anal area with warm water after the bowel movement to improve local blood circulation in the anus. 7, often do anal lifting exercise. Adhere to the daily independent contraction of the anus, 1 time in the morning and evening, each time to do 30 times, exercise the anal sphincter. This method is simple and practical, not limited by time and space, often used, can improve hemorrhoid venous reflux.
