Hemorrhoid

Hemorrhoids, also called piles, are vascular structures in the anal canal. In their normal state, they are cushions that help with stool control. They become a disease when swollen or inflamed; the unqualified term is often used to refer to the disease. The signs and symptoms of hemorrhoids depend on the type present. Internal hemorrhoids are usually present with painless, bright red rectal bleeding when defecating.
