Why does a large hard bowel movement cause bleeding?

A doctor has provided 1 answer

Hemorrhoid/fissure: As the stool passes through the rectum and the anus, it can irritate internal hemorrhoids if they are present, or create a 'cut' in the lining of the anus, called a fissure. Both can bleed, and be precipitated by passage of a large hard stool.
