Can being chronically constipated make urinary incontinence permanent?

Not permanent: Chronic constipation can make urinary incontience worse with the straining but over the long term it is not going to cause it to be permanent. Incontinence can be permanent in many cases anyway.

Possibly: Repeated straining to have a bowel movement causes an increase in the pressure within the abdomen. This, in turn, puts pressure on the structures that support the pelvic organs, including the bladder. Constant straining over years may damage bladder support to the point that stress urinary incontinence becomes permanent.

Maybe: Constipation increases risk of stress incontinence: leaking that occurs with activity, cough, sneeze. This happens because the ligaments under the urethra are stretched or torn thus allowing the urethra to open and leak urine. Once this occurs the ligaments don't heal on their own. However, there are many treatment options. www.voicesforpfd.org
