What is hemorrhoid?
Hemorrhoid is the diseased vascular cushion at the anus. Normally, these vascular cushions are situated in the anal canal between the anal skin and the anal sphincter. It is a sponge like vascular structure and it helps the anal sphincter to prevent leakage of feces or gas through the anal canal. When the anal vascular cushion causing symptom(s) or complication(s), it is called Hemorrhoid and treatment for hemorrhoid is required. The aim of treatment is to reduce the symptoms, but not to remove all vascular cushions.
