Protruding: The anal tissue and the local veins are pushed out and expand over time and pressure. Dry hard stools and constipation are elements of the problem. The anal mucosa over the protruding veins is delicate and if rubbed, wiped too hard will ooze or bleed. If the veins are exposed, significant bleeding can occur.

Pressure and trauma: Hemorrhoids are enlarged veins that exist under the lining of the rectum and anus. The primary cause of hemorrhoids is increased abdominal pressure, from chronic constipation, prolonged sitting, pregnancy and in some cases, from other diseases, such as liver disease. They are usually fleshy and soft but cause discomfort when engorged and bleed with trauma such as passing hard stool or hard wiping.
