Constipation and Pelvic Floor Dyssynergia – What Do They Have In Common?

What is Pelvic Floor Dyssynergia?

Pelvic floor dyssynergia is known by many different names including: anismus, puborectalis dyssynergia, paradoxical puborectalis, obstructive defecation, dyssynergic defecation, pelvic outlet obstruction, and pelvic floor dysfunction. To put it simply the pelvic floor muscles are overactive, tight or non-relaxing.

What are the Pelvic Floor Muscles?

The pelvic floor muscles are made up of a group of muscles that are both superficial and deep.



The superficial pelvic floor muscles are:

  1. Ischeocavernosus – muscles that go from your pubic bone to your sit bones
  2. Bulbospongiosis – muscles that circle around your urethra and your vagina
  3. Perineum – muscles in the middle of the vagina and anus that extend to your sit bones
  4. Anal sphincter – muscles that circle your anus


The deep pelvic floor muscles are:

  1. Iliococcygeus – muscles that go from the side of your pelvis to the tailbone
  2. Pubococcygeus – muscles that sling from each side of the pubic bone to the tailbone
  3. Puborectalis – muscles that sling from each side of the pubic bone, wrapping around the rectum

Constipation and The Pelvic Floor Muscles

Normally, the pelvic floor muscles tighten to hold your urine and bowel motions in. When you sit on the toilet, the pelvic floor muscles should relax so that you are able to empty your bladder or bowel.

In constipation, the pelvic floor muscles are tight and overactive and do not know how to relax. So when on the toilet the pelvic floor muscles are creating a serious kink on the rectum and it’s very difficult to push the bowel motion out, without straining, pain or causing anal fissures (little tears in the anus).


How to Fix Pelvic Floor Dyssynergia

The pelvic floor muscles need to be released and retrained to relax. This can be done with the help of seeing a women’s health physiotherapist. You can also improve constipation by sitting on the toilet with a stool under the feet and leaning forwards. This position helps relax the pelvic floor muscles so that the bowel motion can come out easier.
