OAB is not a disease. It's the name given to a group of troubling urinary symptoms. The most common is a sudden and unexpected urge to urinate that you can't control. In some people, this "gotta go" feeling may result in urine leakage (incontinence). In others, it may not.Other OAB symptoms include frequent urination during the day and night. The number of times someone goes to the bathroom may vary from person to person. But many experts agree going to the bathroom more than eight times in 24 hours is "frequent urination."OAB affects millions of men and women. Some experts estimate as many as 30 percent of men and 40 percent of women in the United States live with OAB symptoms. But the number of people suffering from OAB may be much larger. That's because many people living with the condition don't ask for help. "A lot of people don't talk to their doctors because they're embarrassed about their symptoms or because they don't know there are treatment options," says Kathleen Kobashi, MD, chief of urology at Virginia Mason Medical Center in Seattle, Washington. "But there are plenty of things we can do to help. If you are having difficulty with OAB symptoms, talk to your health care provider today."
