2、生理结构的缺点和直立体位：杭州医博肛泰医院科普内痔疮人体站立或直坐时，肛门方位低，受地心引力的影响，直肠肛门静脉血液回流受阻挠，直肠上静脉及其分支缺少静脉瓣，血液简略发生瘀积，且直肠血管摆放特别，在不同平面穿过肌层简略受粪便压榨，使粘膜下疏松安排中的静脉简略扩展、曲张而发生痔。杭州医博肛泰医院科普内痔疮.所以有人说痔疮是人体特有的疾病。

After anorectal hospital expert introduction: human rectal submucosal and anal canal skin venous plexus occurred under the expansion and force of soft vein group, called the hemorrhoid, also known as hemorrhoids, haemorrhoids, hemorrhoids, hemorrhoids, etc.
Common cause hemorrhoids occur with the following:
: 1, constipation defecate time is too long or diarrhea for a long time, can make the increased abdominal pressure, anal rectum hyperemia, varicose veins, hemorrhoids and even can cause rectum mucosa and muscle layer out respectively, anal canal down, along with the feces of short piles.
2, the shortcomings of the physiological structure and vertical position: stand or sit straight body, anus bearing is low, the influence of gravity, the anus rectum vein blood flow blocked, rectal vein and its branches without venous flap, on blood YuJi briefly, and rectal blood vessels put special, in different plane through the muscularis brief faecal squeezing, make the submucosal vein brief extension of loose arrangement, varicose and hemorrhoids. So some people say that piles is unique to human disease.
3, infection factors: anal sinusitis, anal gland infection, crissum abscess, dysentery, enteritis, intestinal parasitic disease, colitis and so on, which can cause an inflammation in the rectum bottom arranged around, hemorrhoids overworked, inflammation, make the hemorrhoid venous wall brittle, secondary angiectasis hyperemia and cause or aggravate hemorrhoids.
4, portal hypertension, liver cirrhosis, portal vein thrombosis, inflammation, can lead to portal hypertension, and because of the portal vein system lacks the venous flap, can result in higher pressure of hemorrhoid venous plexus, directly cause hemorrhoids.
5, anal sphincter slack: infirm and multiple damage to the patients with sphincter shape structure, the anus surgery for sphincter weakness exacerbated hemorrhoids prolapse.
6, pregnancy and birth: pregnant women and fetal squeezing pelvic vein, the venous return, anal rectum vasodilation, due to the increasing content of progesterone in the body, together constitute water sodium retention, vasodilation and trigger tumors.
7, genetic elements: about genetic elements, with the concept of western medicine is not yet, need further verification. Some people think that higher incidence of tumors in a clan, may be associated with genetic factors.
