Constipation is when a person suffers from infrequent or tough passing of bowels that lasts from several days to several weeks. It is common among adults, and almost everyone experiences it in their lifetime. Although constipation is common, those suffering from chronic constipation may experience excessive straining that interferes with daily life.

The pelvic floor is the group of muscles and ligaments in the pelvic region. The pelvic floor is a support sling for the organs located there, including the rectum. Up to one-half of those suffering from chronic constipation have pelvic floor dysfunction (PFD) which is impaired relaxation and coordination of pelvic floor and abdominal muscles during evacuation. 

A rectovaginal fistula is an abnormal connection (opening) between the rectum and the vagina. This opening allows gas or stool to pass from the rectum into the vagina. Rectovaginal fistulas most commonly occur as a result of childbirth-related trauma, particularly following difficult or prolonged vaginal deliveries.
