Hemorrhoids are also called hemorrhoids, and the professional name is hemorrhoids. Let us first look at the origin and meaning of the word "hemorrhoids". The earliest prototype can be found in the oracle bone inscriptions as early as 3000 years ago. In some medical books of the Spring and Autumn Period, there were some "Temple" and "Zhi" besides the word 疒 to record and describe the disease. It experienced the late Warring States period. The current "hemorrhoids" really appeared in "Fifty-two Recipes for Diseases". The "Compendium of Medicine" of the Ming Dynasty explained the meaning of this word as saying: "There are hills that stand out in the Daze, and in the nine orifices of a person, where there is a small flesh that protrudes, it is called hemorrhoids.", "If you are full, your stomach will be full. The intestines and stomach are full, the muscles and veins are unresolved, so the intestines are called hemorrhoids.” This is the discussion of the pathogenesis of hemorrhoids in the "Huang Di Nei Jing". Therefore, in ancient China, people’s main understanding of hemorrhoids was based on the local protrusion of the anus. A characteristic type of disease is closely related to diet. There are two English words for hemorrhoids, one is Hemorrhoids from ancient Greek, which means bleeding or bleeding. The other is from the Latin word pile, which means spherical or protruding. The two words describe the symptoms and shapes respectively.
So this "protrusion" in the anus must be hemorrhoids? No. 2500 years ago, why did the ancient Chinese use the words "Temple" and "Zhi" without the word 疒 to express it. Although Hemorrhoids that appeared at almost the same period refer to bleeding or bleeding, they were not regarded as diseases at that time, because ancient Western scholars regarded hemorrhoid bleeding as a self-purifying life phenomenon. In 1975, American scholar Thomson found spongy-like protruding tissues in the lower rectum of normal people, arranged in 3, 7, and 11. He believes that the tissue is not only not a disease, but can also act as a cushion to help close the anus tightly. Therefore, he named it "anal cushion".
So what exactly is hemorrhoids? Traditional textbooks say: “Hemorrhoids are raised tissues formed by the tortuous expansion of the anal margin, anal canal, and lower rectum”. This definition gives a clear definition of the location of the disease and the nature of the disease. Thomson’s "anal cushion" theory has further enriched and improved the meaning of hemorrhoids, and industry organizations have supplemented and revised the definition of hemorrhoids, "Hemorrhoids are pathological hypertrophy, displacement, and stagnant masses of blood flow in the subcutaneous vascular plexus perianal." Internal hemorrhoids are the pathological expansion or proliferation of blood vessels above the dentinal line of the anal canal and under the rectal mucosa." Studies have confirmed the four pathological changes of hemorrhoids, namely venous vasodilation, intravascular or thrombosis, tissue edema and inflammation.
