Overview of hemorrhoids

Hemorrhoids are vascular structures present in the anal canal. In normal condition, hemorrhoids work as cushions that help in bowel control.

At times, the walls of these blood vessels stretch in a way that veins bulge out. This happens especially during the bowel movement. When these veins present in anus and rectum get inflamed and swollen, they cause a disease called as piles (or hemorrhoids). The term “hemorrhoids” may be misleading sometimes.
