Swollen or enlarged veins in the anal canal. Hemorrhoids are a common problem in both men and women after age 50. Also known as piles, hemorrhoids can be internal or external. Internal hemorrhoids arise near the beginning of the anal canal and cannot be seen with the naked eye. External hemorrhoids are visible as a bulge under the skin outside the anus.
Enlarged (varicose) veins in the wall of the anus (internal hemorrhoids), usually a consequence of prolonged constipation or, occasionally, diarrhea. They most commonly occur at three main points equidistant around the circumference of the anus. Uncomplicated hemorrhoids are seldom painful; pain is usually caused by a fissure. The main symptom is bleeding, and in first-degree hemorrhoids, which never appear at the anus, bleeding at the end of defecation is the only symptom. Second-degree hemorrhoids protrude beyond the anus as an uncomfortable swelling but return spontaneously; third-degree hemorrhoids remain outside the anus and need to be returned by pressure.
Haemorrhoids, or piles, are varicose (swollen) veins in the lining of the anus. They are very common, affecting nearly half of the UK population at some time in their lives, with men suffering more severely.
