Definition:
Prolapsed hemorrhoids are internal hemorrhoids that protrude out of the rectum.
Prolapsed hemorrhoids are graded on a scale depending on severity. Grade II hemorrhoids may push out of the rectum during a bowel movement, but then retract without any intervention on your part. Grade III hemorrhoids can be gently pushed back into the rectum, where they will then remain. Grade IV hemorrhoids are those that cannot be pushed back in, or will not remain within the rectum. A Grade IV hemorrhoid runs the risk of becoming a thrombosed hemorrhoid.
