A

Diminished ability of kidney to concentrate urine ( nocturia night peeing )

Decrease bladder contractility may lead to urine de ruin and stasis which increases possible uti

Dresses bladder muscle tone , decrease the possibility of holding urine in bladder which increase frequent urination

Neuromuscular problems , joint probs ,
Alteration is thought process, and weakness’s, affect reaching the restroom in time
