Hemorrhoids – How Are They Caused?
April 15, 2017

Contrary to popular belief, Hemorrhoids are normal parts of the human anatomy. They are the blood vessels found in the smooth muscles lining the walls of the rectum and the anus, located at the connection where the arteries merge the veins. The smooth muscles and connective tissue serve as their cushions.

There are actually two types of hemorrhoids. They are classified according to their location relative to the pectinate line – which serves to divide the upper and the lower half the anus. Aside from that, type of cells that cover the hemorrhoid also serve as important anatomical markers.

  • Internal hemorrhoids – These can be found in the upper section of the anus, above the pectinate line. They are covered with cells similar to those that line the rest of the intestines.
  • External hemorrhoids – These can be found below the pectinate line and are covered with cells resembling skin.

Reader should understand that hemorrhoids only become a problem when adverse symptoms start to appear. Namely, swelling, sensations of itching, pain and bleeding. These are the red flags that you have to watch out for. Once they appear, you must visit your doctor immediately.
