According to domestic and foreign surveys, adults suffering from hemorrhoids reach 60-70%. Why are there so many people suffering from hemorrhoids? The famous medical classic “Yellow Emperor’s Classic of Internal Medicine” pointed out as early as 2,000 years ago that it was related to poor diet, dampness and heat from time to time. In the Tang and Song dynasties, medical doctors also pointed out that it was related to long-suffering stools, long-standing diarrhea and dysentery, excessive alcohol consumption, excessive spices, deficiency of gas in the elderly, pregnancy in women, and long sitting and long walking. Modern medicine believes that the causes of hemorrhoids are the following: 1, and human upright posture related to the investigation: cattle, horses, dogs, rabbits and other four-legged reptiles shall not hemorrhoids, only upright humans are susceptible to hemorrhoids. So some people believe that hemorrhoids is a disease that is unique to reptiles after they evolved into bipedal upright people. The argument is that although humans have become erect, the evolution of the rectal-anal region has not developed to adapt to an erect posture. From the anatomical aspect, the superior rectal vein and its branches have no venous valves, and when they return to the heart from the bottom up through the rectal muscle layer, under the influence of geocentric attraction, the recto-anal region located in the lower part of the body is prone to blood stasis and varicose veins, and if they are in this unchanging upright position for a long time, hemorrhoids will be formed. From the clinical aspect, people who suffer from liver stiffness, congestive heart disease, larger tumors in the abdomen, emphysema and other diseases that can lead to lower pelvic depression, as well as women after pregnancy, are prone to varicose veins into hemorrhoids after the fetal pressure blocks the return of rectal blood. These reflect that obstruction of blood return is an important reason for the formation of hemorrhoids. The rectal-anal part of the reptile is higher than the heart, so the blood is returned from the top to the bottom, so it is not easy to produce obstructed reflux and the influence of geocentric attraction to the rectal-anal depression of blood, so there is no hemorrhoid disease in animals. 2, and bad defecation habits related to habitual constipation or defecation difficulties, or people who like to squat in the toilet to read books and newspapers, because of forceful defecation, or squatting for too long is easy to lead to recto-anal congestion, pressure, varicose veins, and even make the rectal mucosa and muscle layer relaxation or separation, prolapse out of the anus, so easy to suffer from hemorrhoids. 3, related to infection dysentery, enteritis, pinworms and other parasites, perianorectal abscess, anal fistula and other diseases, can cause hemorrhoid perivenous inflammation or hemorrhoid vein endocarditis, so that hemorrhoid vein congestion, expansion, induced hemorrhoids. The large amount of alcohol, spicy food, such as chili, mustard, pepper, ginger and other irritating foods also easily irritate the mucosal skin of the rectum and anus, local congestion and burning pain, which can be a trigger for hemorrhoids or aggravate the condition. The occurrence of hemorrhoids is often a combination of these factors. This may be because children and teenagers have good vascular elasticity and are in the process of development, plus they are active and change positions, so it is not easy to form depressed blood in the anus. The older you get, the more you develop hemorrhoids, which may be related to the fact that blood vessels gradually harden and lose their elasticity as people age, and that you don’t want to be more active, or engage in sedentary work.
