Could you tell me what are hemorrhoids ?

Dilated veins: Located in the rectum. They begin when constipation causes high pressures to build up. The normal veins in the area get blocked from the pressure and stretch. They may become inflamed from a clot or they may never bother you. Best care will be stool softeners and a good bowel habit. Better still is to perform this before they ever form.

Piles: A hemorrhoid is a enlarged vein at the anus or in the lower rectum. Internal hemorrhoids are deep to the anus. External hemorrhoids are outside of the anus. A hemorrhoid is a bump that can cause pain, bleeding and may be itchy.
