The soft venous mass formed by the dilatation and flexion of the venous plexus under the mucous membrane at the end of the human rectum and the skin of the anal canal is called hemorrhoid, also known as hemorrhoid, hemorrhoid, hemorrhoid disease, hemorrhoid disease, etc. In Chinese medicine, the meaning of hemorrhoids has been discussed more, such as in “Shuowen Jiezi”, which says: “After the disease also.” In “Adding Rhymes”, it says: “Hidden sore also.” It explains that hemorrhoids are small fleshy protrusions inside and outside the anus that are superfluous in different shapes and with different evidence. Hemorrhoids are a common and frequent disease that is unique to humans. According to the census data, the incidence of anorectal diseases is 59.1%, and hemorrhoids account for 87.25% of all anorectal diseases, of which internal hemorrhoids are the most common, accounting for 52.19% of all anorectal diseases. The incidence of hemorrhoids is 67% for women and 53.9% for men; they can develop at any age, and are more common in people aged 20-40, and gradually increase with age, so there are “nine hemorrhoids in ten people”. The former is named after the clinical feature of bleeding, while the latter is named after the outer shape of hemorrhoids, which resembles a ball and refers to both internal and external hemorrhoids. At present, British scholars mostly call hemorrhoids as Piles, while American scholars call them Hemorrhoids. Medical hemorrhoids include internal, external and mixed hemorrhoids, which are a chronic disease of one or more soft venous masses formed by varicose veins at the base of the anorectum and anal mucosa. Usually when straining continuously during defecation causes a repeated increase in pressure in the veins here, the veins become enlarged. Hemorrhoids often occur in women during pregnancy due to compression of the pelvic veins, which hinders blood circulation, and many obese people also suffer from hemorrhoids. If you have hemorrhoids, the walls of the enlarged and twisted veins in the anus become very thin, so they can easily rupture during defecation. Internal hemorrhoids are those that grow at the beginning of the anal canal. If the swollen vein is located further down, almost over the opening of the anal canal, this varicose vein is called an external hemorrhoid. External hemorrhoids can sometimes protrude or protrude outside the opening of the anal canal. However, this only happens during a bowel movement, and it retracts back to its original position afterwards. Blood clots can occur in both internal and external hemorrhoids. In the event of a clot, the blood in the hemorrhoid clots and causes pain.
