Symptoms of overactive bladder (OAB) result from sudden and involuntary contractions of the bladder muscles, leading to a
- sudden need to urinate (urinary urgency) and/or
- urinary incontinence (leakage of urine).
In addition to urinary urgency and incontinence, symptoms of overactive bladder can include
- urinary frequency (having to urinate often),
- nocturia (urinating frequently at night).
Overactive bladder can affect anyone but is more common in older people. However, it is not considered to be a normal part of aging. Because there are number of causes of overactive bladder, other symptoms may occur that are related to the underlying cause (for example, stroke, dementia, Parkinson's disease, diabetes).
