We are all born with normal hemorrhoids. The functions of hemorrhoids when they are not diseased are:
1st: Temperance, ie to close the anus properly.
2nd: The protection, ie they protect the intestinal mucosa from injuries due to hard bowel movements or diarrhea. Hemorrhoids are therefore vascular cushions, protecting the intestine
When the hemorrhoids are sore, that is, they swell and come out of the intestine, then we have hemorrhoids.
