A mass of dilated, tortuous veins in the anorectum, hemorroids come in two kinds: external,
which involves veins distal to the anorectal line; and internal, which involves those veins
proximal to the anorectal line. Prolapsed hemorroids are those internal dilated veins
protruding through the anus, while strangulated hemorroids are trapped by the anal sphincter,
cutting off blood flow to the vein in the hemorrhoid. They are usually caused by straining
to have a bowel movement or pushing in childbirth.

![]() en million people in the
United States alone have hemorrhoids. The peak age range to have an occurrence of
hemorrhoids is between 45 and 65. Typical symptoms are rectal pain, burning or
itching, and bright red blood on the toilet tissue or on the stool. Rounded swellings
or protrusions from the anal area may
also be present. Because all of these symptoms can be caused by other, more
serious conditions, those who suffer from hemorrhoids should be alert to the possibility
of inflammatory bowel diseases, ulcerative colitis, and Crohn's disease. ![]() ![]() |
