Internal hemorrhoids are a fairly common condition occurring within the anal canal, and many people unknowingly have small internal hemorrhoids that don’t cause problems. Internal hemorrhoids are classified according to a system of grades. Hemorrhoids’ degrees are:
1st degree: Hemorrhoids bulge into the anal canal during bowel movements and may cause some symptoms (bleeding, itching etc.).
2nd degree: First stage of hemorrhoidal prolapse. The hemorrhoids protrude from the anus during bowel movement, then retract back into the body by themselves.
3rd degree: The hemorrhoids protrude from the anus during bowel movement but will stay inside if pushed back in manually (e.g by using a finger). The symptoms of 3rd degree hemorrhoids include bleeding and inflammation.
4th degree: The hemorrhoids protrude from the anus all the time. If pushed back in, they will slip out on their own shortly with no effort required.
