杭州医博肛泰医院痔疮的形成-痔疮发病率一贯居高不下，有些患者就想追根问底，想要了解痔疮是怎样引起，得了痔疮疾病要尽早医治检查！下面看看 肛肠医院给咱们介绍是哪些原因导致痔疮的发生?
杭州医博肛泰医院痔疮的形成
（1）人体生理结构的缺点和直立体位：杭州医博肛泰医院痔疮的形成人体站立或直立时，肛门方位低，受地心引力的影响，直肠肛门部的静脉血液回流阻碍。直肠上静脉及其分支短少静脉瓣，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。所以有人说痔疮是人体特有的疾病。
（2）便秘与腹泻：排便时刻过长或腹泻，杭州医博肛泰医院痔疮的形成可使腹压增高，肛门直肠部充血，痔静脉曲张，乃至可导致直肠粘膜与肌层别离脱出，肛管随粪便下移，久之简略发生痔疮。
（3）感染要素：肛窦炎、肛腺感染、痢疾杭州医博肛泰医院痔疮的形成、肠炎、肠道寄虫病等，可引起直肠下部周围安排的炎症，痔静脉劳累，进而使痔静脉管壁脆弱，继则血管扩张、充血而引起或加重痔疮。
（4）妊娠与临产：妊娠妇女，杭州医博肛泰医院痔疮的形成因为胎儿压榨盆腔静脉使回流受阻，肛门直肠部血管扩张，一同因为体内孕激素含量上升，构成水钠潴留，血管扩张而诱发痔疮。
（5）肛门括约肌松驰：杭州医博肛泰医院痔疮的形成年老体弱及多次肛门手术而损坏括约肌无缺结构的患者，因括约肌无力使痔脱垂加重。
（6）门静脉高压：肝硬变、门杭州医博肛泰医院痔疮的形成静脉血栓炎等，可引起门静脉高压，因为门静脉系统短少静脉瓣，可直接导致痔静脉压力升高，引起痔疮。
（7）肿瘤：腹部和盆腔的肿瘤，如直肠肿瘤，卵巢肿瘤和子宫肌瘤等均可压榨盆腔静脉，使痔静脉回流受阻而发生痔疮。

(6) of the portal hypertension, liver cirrhosis, door hangzhou bo anus tai hospital hemorrhoids venous thrombosis inflammation, can lead to portal hypertension, because of shortage of portal venous system venous flap, can directly lead to hemorrhoids venous pressure, cause hemorrhoids.
Tumors (7) : the abdominal and pelvic tumors, such as colorectal cancer, ovarian cancer and uterine fibroids, etc all can squeeze the pelvic vein, make hemorrhoid venous return obstruction and hemorrhoids.
(8) genetic elements: about genetic elements, hangzhou medical bo anus tai hospital piles with the formation of western medicine concept is not, need further verification. Some people think that the piles on the pathogenesis of a family is higher, perhaps have factors of genetic factors
