By definition, postpartum pelvic floor dysfunction only affects women who have given birth, though pregnancy rather than birth or birth method is thought to be the cause. A study of 184 first-time mothers who delivered by Caesarean section and 100 who delivered vaginally found that there was no significant difference in the prevalence of symptoms 10 months following delivery, suggesting that pregnancy is the cause of incontinence for many women irrespective of their mode of delivery. The study also suggested that the changes which occur to the properties of collagen and other connective tissues during pregnancy may affect pelvic floor function.[7]

The pelvic floor is a combination of multiple muscles with ligamentous attachments creating a dome-shaped diaphragm across the boney pelvic outlet. This complex of muscles spans from the pubis (anterior) to the sacrum/coccyx (posterior) and bilateral to the ischial tuberosities. The bulk of the pelvic musculature is the levator ani, composed of the puborectalis, pubococcygeus, and iliococcygeus. The puborectalis wraps as a sling around the anorectal junction accentuating the anorectal angle during contraction and is a primary contributor to fecal continence. Elevation and support of the pelvic organs are associated with the pubococcygeus and the iliococcygeus. The pubococcygeus is the most medial component which separates, fashioning the levator hiatus with openings for the urethra, vagina (females), and anus. The bulbospongiosus and ischiocavernosus muscles are the primary contributors to the superficial portion of the anterior pelvic floor. The more superficial musculature of the posterior pelvic floor constitutes the external anal sphincter. The transverse perineal muscles cross the mid-portion of the superficial aspect of the pelvic floor and coalesce with the bulbospongiosus muscles and external anal sphincter as the perineal body.
Biofeedback: This is the most common treatment, done with the help of a physical therapist. Biofeedback is not painful, and helps over 75% of people with pelvic floor dysfunction. Your physical therapist might use biofeedback in different ways to retrain your muscles. For example, they may use special sensors and video to monitor the pelvic floor muscles as you try to relax or clench them. Your therapist then gives you feedback and works with you to improve your muscle coordination.

Medications: Daily medications that help to keep your bowel movements soft and regular are a very important part of treating pelvic floor dysfunction. Some of these medications are available over-the-counter at the drugstore and include stool softeners such as MiraLAX®, Colace®, Senna or generic stool softeners. Your primary care doctor or a gastroenterologist can help to advise you which medications are most helpful in keeping your stools soft.
Pelvic floor dysfunction is very different than pelvic organ prolapse. Pelvic organ prolapse happens when the muscles holding a woman’s pelvic organs (uterus, rectum and bladder) in place loosen and become too stretched out. Pelvic organ prolapse can cause the organs to protrude (stick out) of the vagina or rectum and may require women to push them back inside.
Pelvic floor dysfunction can be diagnosed by history and physical exam, though it is more accurately graded by imaging. Historically, fluoroscopy with defecography and cystography were used, though modern imaging allows the usage of MRI to complement and sometimes replace fluoroscopic assessment of the disorder, allowing for less radiation exposure and increased patient comfort, though an enema is required the evening before the procedure. Instead of contrast, ultrasound gel is used during the procedure with MRI. Both methods assess the pelvic floor at rest and maximum strain using coronal and sagittal views. When grading individual organ prolapse, the rectum, bladder and uterus are individually assessed, with prolapse of the rectum referred to as a rectocele, bladder prolapse through the anterior vaginal wall a cystocele, and small bowel an enterocele.[10]
Electrical stimulation uses a small probe inserted into the vagina or rectum to stimulate your pelvic floor muscles, helping desensitize nerves and causing muscles to contract and relax. Stimulation through electrodes placed on your body may calm pain and spasms. Different kinds of electrical stimulation devices are available for home use, both for internal stimulation with a probe or for external stimulation, such as a transcutaneous electrical nerve stimulation (TENS) or similar unit, to ease pain.

You’ve likely already heard of kegels, the most common method for strengthening the pelvic floor. But there are plenty of additional exercises you can try to help train your pelvic floor. Watch this video to see yoga and fitness expert Kristin McGee (who recently gave birth to twins!) demonstrate three simple yet effective moves for strengthening your pelvic floor.
