You are most likely experiencing rectal bleeding due to inner hemorrhoids and rectal prolapse.
Inner hemorrhoids are swollen veins inside the anal canal and usually, cause, bright red bleeding.
Chronic constipation and straining during bowel movement are major causes for developing hemorrhoids.
Having inner hemorrhoids, predispose the rectum to prolapse.
Rectal prolapse means rectal slipping or falling out of the place.
When long-term hemorrhoidal disease is the cause, the prolapse is usually partial and only the inner lining of rectum (mucosa) is protruding out of the canal, when the connective tissue of the mucosa loosens and gets stretched.
