Haemorrhoids痔疮

Haemorrhoids, also known as piles are rather like varicose veins in the canal of the anus.痔疮，也称为桩，而不是像静脉曲张，在运河的肛门。 Here, just under the mucous membrane inner lining, is a considerable network of veins extending upwards for an inch or so from the level of the skin to just above the anal canal, where it joins the rectum.在这里，刚刚下粘膜膜内衬，是一项相当大的网络，静脉向上延伸为1英寸或因此，从水平的皮肤只以上的肛管，在那里加入直肠。 When the veins of this network become swollen with blood, haemorrhoids occur.时脉这个网络成为肿胀，用鲜血，痔疮发生。

The vein swelling can affect the part of the network just above the anal canal, where it is less well supported by the muscular ring (sphincter), and this causes internal haemorrhoids.静脉肿胀，可能会影响网络的一部分略高于肛管，这是不太好的支持，肌肉环（括约肌） ，这将导致内部痔疮。 Or it may affect the veins at the lower end of the canal, just under the skin, causing external haemorrhoids.或者它可能会影响静脉在低端运河，只是皮肤下，造成外部痔疮。 Some people have both.有些人同时拥有。
