Everyone has veins (low pressure blood vessels that return blood to the heart) around the anal opening. When these veins become abnormally enlarged or dilated, they are called "hemorrhoids".(see left fig.) Internal hemorrhoids occur above the dentate line and are, therefore, usually painless. They can cause bleeding or they may push out of (prolapse) the anal opening when they become quite large. (see left fig.) :Prolaps (come out of the anal opening). |
