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.
Pelvic floor dysfunction is an umbrella term for a variety of disorders that occur when pelvic floor muscles and ligaments are impaired. Although this condition predominantly affects females, up to 16% of males suffer as well.[1] Symptoms include pelvic pain, pressure, pain during sex, incontinence, incomplete emptying of feces, and visible organ protrusion.[2] Tissues surrounding the pelvic organs may have increased or decreased sensitivity or irritation resulting in pelvic pain. Underlying causes of pelvic pain are often difficult to determine.[3] The condition affects up to 50% of women who have given birth.[4]

If you think of the pelvis as being the home to organs like the bladder, uterus (or prostate in men) and rectum, the pelvic floor muscles are the home’s foundation. These muscles act as the support structure keeping everything in place within your body. Your pelvic floor muscles add support to several of your organs by wrapping around your pelvic bone. Some of these muscles add more stability by forming a sling around the rectum.
To assess the degree of dysfunction, three measurements must be taken into account. First, an anatomic landmark known as the pubococcygeal line must be determined, which is a straight line connecting the inferior margin of the pubic symphysis at the midline with the junction of the first and second coccygeal elements on a sagittal image. After this, the location of the puborectalis muscle sling is assessed, and a perpendicular line between the pubococcygeal line and muscle sling is drawn. This provides a measurement of pelvic floor descent, with descent greater than 2 cm being considered mild, and 6 cm being considered severe. Lastly, a line from the pubic symphysis to the puborectalis muscle sling is drawn, which is a measurement of the pelvic floor hiatus. Measurements of greater than 6 cm are considered mild, and greater than 10 cm severe. The degree of organ prolapse is assessed relative to the hiatus. The grading of organ prolapse relative to the hiatus is more strict, with any descent being considered abnormal, and greater than 4 cm being considered severe.[2]
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]

Pelvic floor dysfunction is a common condition where you’re unable to correctly relax and coordinate the muscles in your pelvic floor to urinate or to have a bowel movement. If you’re a woman, you may also feel pain during sex, and if you’re a man you may have problems having or keeping an erection (erectile dysfunction or ED). Your pelvic floor is a group of muscles found in the floor (the base) of your pelvis (the bottom of your torso).

“I would recommend that people call the facility and maybe schedule the first appointment and see how you feel about it. I also think patient support groups tend to have closed Facebook groups and they can recommend people in certain geographical areas. I know people call [our practice] a lot and we try and get them paired up with somebody we trust in their area,” Prendergast says.
