5. Rectal mucosal prolapse: it can also be called "proctoptosis", as the name implies, the tissue inside the anus is pulled out of the anus.

Diarrhea is similar. In some cases, bacteria can be cultured in feces, and in some cases, antibacterial drugs are effective. Therefore, some people think that infection is the cause of this disease.
