No specific behaviors (such as smoking) are known to increase your risk of IC. Having a family member with IC/BPS may increase your risk of getting IC/BPS. Patients with IC/BPS may have a substance in the urine that inhibits the growth of cells in the bladder tissue. So, some people may be more likely to get IC/BPS after an injury to the bladder, such as an infection.
At this time, there is no medical test that can say a person has IC/BPS. Also, there is no test to say a person does not have IC/BPS. To make a diagnosis, your urologist will first decide whether the symptoms are typical of IC/BPS. Next, they need to rule out other health issues that might be causing the symptoms. More tests may be needed to find out whether the patient has IC/BPS.
