CHICAGO--(BUSINESS WIRE)--Results from a nationwide survey of women ages 40 to 65 show that the symptoms of overactive bladder (OAB) are compromising their sense of normalcy and making their complicated lives even more difficult to manage. The survey, conducted for The National Association For Continence (NAFC) by Kelton Research and sponsored by Medtronic, Inc., (NYSE: MDT) compared women ages 40 to 65 who have experienced symptoms of OAB, which affect as many as 33 million Americans, to women in the same age group overall. Survey results were unveiled during the American Urological Association Annual Meeting being held April 25 through April 30 in Chicago.
