Overactive bladder (OAB) is a condition that causes the feeling of sudden and often uncontrollable need to urinate.
Some patients will experience these urges with a full bladder and others with a rather empty bladder. The symptoms can happen during the day and at night. These urges or spasms of the bladder may cause frequency of urination and, at times, leakage of urine. This can cause embarrassment and lead to withdrawal and social isolation. Often people will limit their activities and interactions over concern about frequent bathroom trips and the possibility of leakage.
