Hemorrhoids are swollen blood vessels in the rectal area, and can be located internally or externally. They cause an uncomfortable burning or itching sensation and perhaps some bleeding as well. Millions of people suffer from hemorrhoids. There are over-the-counter remedies to reduce the swelling and itching. Surgery could be required in extreme cases. Having frequent diarrhea can contribute to the development of hemorrhoids in a couple of ways.
One of the common causes of hemorrhoids is straining during a bowel movement. This causes the veins and tissue around the anus to stretch out, and when blood pools in the area a hemorrhoid is formed. Having diarrhea can provoke excessive straining.
Proper cleaning of the anus is important to prevent hemorrhoids. Wiping too hard or excessively can cause the same kind of swelling as straining can. Frequent diarrhea can cause a superfluous amount of wiping, leading to the formation of hemorrhoids.
