When mechanical, anatomic, and disease- and diet-related causes of constipation have been ruled out, clinical suspicion should be raised to the possibility that PFD is causing or contributing to constipation. A focused history and digital examination are key components in diagnosing PFD. The diagnosis can be confirmed by anorectal manometry with balloon expulsion and, in some cases, traditional proctography or dynamic magnetic resonance imaging defecography to visualize pathologic pelvic floor motion, sphincter anatomy and greater detail of surrounding structures.
Many people with interstitial cystitis (IC) have problems with the group of muscles in the lower pelvic area and develop a condition called pelvic floor dysfunction (PFD). If you have IC and a poor urine stream, feel the need to push or bear down to urinate, and have painful intercourse, you may have PFD. Treating PFD may be very helpful in reducing symptoms and pain for some IC patients—most patients see improvement after several weeks of therapy.
Once patients with pelvic floor constipation have these basic tools, they can begin retraining the pelvic floor muscles with biofeedback. Based on the principle of operant conditioning, biofeedback provides auditory and visual feedback to help retrain the pelvic floor and relax the anal sphincter. Biofeedback training is the treatment of choice for medically refractory pelvic floor constipation, with some studies showing improvement in more than 70 percent of patients. Patients also learn to identify internal sensations associated with relaxation and long-term skills and exercises for use at home.
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.
The “pelvic floor” refers to a group of muscles that attach to the front, back, and sides of the pelvic bone and sacrum (the large fused bone at the bottom of your spine, just above the tailbone). Like a sling or hammock, these muscles support the organs in the pelvis, including the bladder, uterus or prostate, and rectum. They also wrap around your urethra, rectum, and vagina (in women).
Kegels: American gynecologist Arnold Kegel created this seminal pelvic floor exercise. To do a Kegel, contract your muscles that stop the flow of urine, hold for five seconds, then release for five seconds. Repeat this exercise 10–15 times, up to three times per day. Avoid doing Kegel exercises when urinating since stopping the flow midstream can cause some urine to remain in your bladder, putting you at a higher risk of urinary tract infections (UTIs).
