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.
