Hemorrhoids is a common disease located in the anal area, any age can be onset, but with age, the incidence rate gradually increased. In our country, hemorrhoids are the most common anorectal disease, there are “ten men nine hemorrhoids”, “ten women ten hemorrhoids” said. What are the causes of hemorrhoids? (1) increased abdominal pressure, such as pregnant women, elderly patients with chronic bronchitis, increased abdominal pressure, which can lead to poor blood return, vascular expansion hemorrhoids. (2) constipation Long-term constipation patients, hemorrhoidal varicose veins, while some muscle fibers in the anal cushion after long-term stretching elasticity is reduced, so that the anal cushion downward, can lead to hemorrhoids. (3) the influence of irritating food Long-term eating irritating food can make the intestines accumulate heat, dry stools, causing hemorrhoids; coupled with the blood-activating effect of irritating food, can induce hemorrhoidal bleeding. (4) Occupational factors Sitting and standing for a long time can form the anal blood return obstacle, so that the rectal veins are stagnant and dilated to form hemorrhoids. (5) The influence of local inflammation Repeated perianal infection inflammation can lead to perivenous inflammation and induce hemorrhoids. (6) Physical weakness Physical weakness of the patient in the lack of Qi, muscle weakness, resulting in the anal cushion downward, coupled with lower body resistance, easy to infect and trigger hemorrhoids. (7) Emotional factors Excessive emotional fluctuations can affect qi and blood regulation, causing neuroendocrine dysfunction, affecting the whole body to the local, forming hemorrhoids. (8) genetic factors As hemorrhoids and blood vessels, if the venous wall is congenitally weak, less elastic fibers within the blood vessel wall, more collagen fibers, reduced elasticity is prone to develop, therefore, the genetic factors on the onset of hemorrhoids have a certain impact. High incidence of hemorrhoids, there can be more than one member of the family at the same time, may be similar with the family’s dietary habits are also related.
