What causes OAB?
In most cases, the cause of OAB is unknown. However, drug side effects, nerve damage or neurological disease (such as Multiple Sclerosis, Parkinsons disease, etc.) or stroke can cause symptoms like OAB. Other conditions, including bladder cancer, urinary tract infections and enlarged prostate can change the urgency and how often you have to void. A medical exam may help find the cause of the OAB symptoms.
