Internal hemorrhoids - Definition

Ask a question


Hemorrhoids are caused by abnormal and permanent dilation of veins located in the anus and rectum. They can be external when they develop below the anal sphincter, the muscle involved in the process of defecation, and can then be visible. Internal hemorrhoids are located above the anal sphincter. Internal hemorrhoids can cause great pain in the backside as well as red blood found in the stool or on the toilet paper. They can also sometimes be externalized. Regularization of constipation is the first step of treatment, more or less associated, if necessary, with the prescription of laxatives. Internal hemorrhoids can be treated by several techniques such as surgical hemorrhoidectomy, rubber band ligation by placing a sort of elastic at the base of the hemorrhoid, or photocoagulation using the energy of light rays .
