Exercises after childbirth also help prevent bladder problems in middle age. Ask your health care team how to do pelvic exercises. Your bladder is a muscle shaped like a balloon. While the bladder stores urine, the bladder muscle relaxes. When you go to the bathroom, the bladder muscle tightens to squeeze urine out of the bladder.
More muscles help with bladder control.
Urine leaves your body through this tube. The sphincters keep the urethra closed by squeezing like rubber bands. Pelvic floor muscles under the bladder also help keep the urethra closed. When the bladder is full, nerves in your bladder signal the brain. That's when you get the urge to go to the bathroom.
