Overactive bladder is a fairly common condition, which affects about 33 million Americans.

This equates to about 30 percent of all men and 40 percent of all women in the United States living with symptoms of an overactive bladder. An overactive bladder is not an illness per say, but rather a term used to describe a set of particular urinary symptoms such as incontinence, frequent urination, and waking up at night to urinate.
