Interstitial Cystitis (IC), also known as Bladder Pain Syndrome (BPS), is a chronic condition characterized by recurring discomfort or pain in the bladder and surrounding pelvic region. Unlike typical urinary tract infections, IC is not caused by bacteria and does not respond to antibiotics.
The condition affects the bladder wall, potentially causing inflammation and scarring. This can lead to a stiff, less elastic bladder that cannot hold as much urine as a healthy bladder.
IC/BPS affects millions of people, with women being more commonly affected than men. The exact cause remains unknown, but it is believed to involve a combination of factors, including defects in the bladder's protective lining, immune system dysfunction, and increased nerve sensitivity.
IC or recurrent infection?
IC is frequently mistaken for recurrent urinary tract infections. If your urine cultures keep coming back negative and antibiotics don't help, IC may be the cause — see our guide on recurrent UTIs vs interstitial cystitis.
