Overactive bladder (OAB) affects 33 million Americans and as many as one in five people over the age of 40 experience symptoms of the disorder, namely sudden urinary urgency and incontinence. Since OAB incidence increases with age, it is expected that the prevalence of OAB will increase further in the developed world as the aging population grows. Diagnosis and treatment of this widespread condition can present many clinical challenges as even the commonly accepted definition has been controversial. Treatments include dietary and lifestyle changes as well as several types of medications such as anti-cholinergic and anti-spasmodic agents. Part of the Oxford American Pocket Notes series, this monograph is intended for health care professionals who treat patients with overactive bladder. This practical, up-to-date guide covers the pathophysiology, etiology, and clinical features of OAB. In addition, it includes helpful information for differential diagnosis, tips for managing comorbidities, and current guidelines for treatment. Uniquely compact and affordable, this concise book is a perfect resource in a range of care settings such as the hospital, clinic, and nursing home.
