Your bladder sits right behind the pubic bone inside the pelvic bowl and is well supported by the pelvic floor muscles from below, The urethra goes through the pelvic floor muscles and that’s how pelvic floor muscles have the ability to influence both these structures. Mechanically, PFM keeps the urethra closed by creating some tension around it. This tension at rest in PFM allows the bladder to quietly fill to it’s max capacity. When it’s completely full and when you’re ready. to peek the PFM must relax to allow the outflow of the urine through the urethra. Dysfunction in this mechanism can cause issues like urinary urgency/ frequency, urinary leakage, inability to hold the urine or empty the bladder etc.
Although the pelvic region is not just all about the muscles. The pelvic organs (bladder, uterus, Fallopian tubes, ovaries, prostate, rectum), nerves, ligaments, the bony pelvis and the fascia all influence each other and may have impaired mobility in a dysfunctional state. Hyperactivity in the muscles and the nerves in the region can also trigger pain in the bladder.
