Urgency: The major symptom of OAB is a sudden, strong urge to urinate that you can't ignore. This "gotta go" feeling makes you fear you will leak if you don't get to a bathroom right away. You may or may not actually leak with this urge to go.
If you live with OAB, you may also:
Leak urine or have “urge incontinence.” This means urine leaks when you feel the sudden urge to go. This isn’t the same as stress urinary incontinence or SUI . People with SUI leak urine when sneezing, laughing or doing other physical activities.
Urinate frequently. You may need to go to the bathroom many times during the day. The number of times someone urinates varies from person to person. Many experts agree that going to the bathroom more than eight times in 24 hours is “frequent urination.”
Wake up at night to pass urine. If you have to wake from sleep to go to the bathroom more than once a night, it’s a symptom of OAB or nocturia.
