Urinary incontinence is the loss of bladder control. There are several types of urinary incontinence including stress incontinence, where urine leaks during activities that strain the abdomen; urge incontinence, resulting from an overactive bladder that contracts unexpectedly; overflow incontinence, which occurs when the bladder weakens or a blocked urethra prevents normal emptying; retention problems that occur when urine cannot be released from the bladder; and problems with urgency and frequency, when there’s an uncontrollable urge to urinate resulting in emptying the bladder more often than normal.
