What Is Overactive Bladder (OAB)?

Learn about Overactive Bladder (OAB), leaks and sudden urges

OAB is not something you need to just accept

Living with OAB symptoms (leaks, strong sudden urges to go, and going too often) can be disruptive.

For instance, you may keep pads on hand or know where all the bathrooms are when you’re out, or maybe you often stay home instead of going out for fear of not making it to a bathroom in time.

But you can do more than just deal with OAB symptoms.

OAB is a treatable medical condition

OAB happens when the bladder muscle starts squeezing to push urine out
before you’re ready to go—even if your bladder isn’t full. These contractions
can create strong, sudden urges to go, which can lead to leaks.

You’ve probably continued to deal with OAB symptoms because you thought they were just an unavoidable part of getting older. Or because you had children many years ago. Neither is necessarily true. OAB is not something you need to just accept.

An estimated 46 million—about 1 in 3—US adults aged 40 and older reported OAB symptoms at least sometimes in the past 4 weeks. While it does become more common as people get older, OAB can happen at almost any age.

Since OAB is a medical condition, prescription TOVIAZ® (fesoterodine fumarate) can help significantly reduce its symptoms of leaks, strong sudden urges to go, and going too often in adults.

This section will tell you more about the causes and symptoms of OAB. But it might help to start with some bladder basics.
