For what is hemorrhoids?" One of the most basic questions seem simple, but it will make even the experts engaged in anorectal work for many years is very difficult to answer, because what is hemorrhoids? At present, it is not completely clear, to achieve a unified understanding, there are still disputes. What is the theory about hemorrhoids has reached more than ten kinds, such as varicose veins, vascular proliferation theory theory, theory of infection, pressure gradient change theory, hemorrhoids hernia theory, rectal artery branch stenosis of anal canal theory, theory, theory of erectile tissue and antral vein theory, anorectal drop theory, anorectal force imbalance allergic reaction theory, anal sphincter dysfunction theory, hemorrhoid venous pump function decline theory and so on, each theory has more or less advocates, hemorrhoids can be explained in one or two aspects, but can not complete the "what is hemorrhoids?" Explain thoroughly.
Now I will be in the present to get a relatively many scholars agree that the understanding of the more consistent interpretation of the theory of hemorrhoids anal pad down to everyone to introduce the theory, it is "what is hemorrhoids?"

When it comes to anal down theory, then you must first figure out what is the anal pad, pad anal anal cushion is referred to, is under the normal tissue structure of human rectum, composed of rich blood vessels, muscle tissue and fibrous tissue, with the assistance of anal function is closed, feel very fine, can tell to the anus stool is hard, soft, pulpy stool or not, only the gas (fart). She made a muscle stretch is fixed on the lower rectum, rich in blood vessels, increase with age, as well as in a variety of stimuli, the muscle aging, less elastic, even lead to fracture, anal pad down, which is therefore hemorrhoids venous plexus has occurred, dilated and tortuous blood stasis, so that the formation of hemorrhoids.
Due to the occurrence of hemorrhoids and the different parts, divided into internal and external hemorrhoids and mixed hemorrhoid.
