Urinary incontinence is any involuntary loss of bladder control. When your bladder functions normally, specific nerves send messages from the brain to muscles in the bladder about when to tense up when you want to hold your urine, and relax when you want to urinate. This allows you to control when your urine is released. When you have incontinence, you no longer have complete control. This can range from occasionally leaking urine when you cough or sneeze to having a sudden and uncontrollable urge to urinate, and you can’t get to the toilet fast enough.
