Current studies estimate that 2.7% to 6.5% of women in the United States have symptoms consistent with a diagnosis of interstitial cystitis/bladder pain syndrome (IC/BPS). [32] The broad range in prevalence depends on whether a high-sensitivity definition (6.53%) is used versus a highly specific definition (2.7%). Roughly translated, these numbers indicate that 3.3-7.9 million US women older than 18 years have symptoms of IC/BPS. Of those women, however, only 9.7% report being assigned a diagnosis of IC/BPS. [33]

In the United States, Curhan et al showed a prevalence of 60-70 cases per 100,000 women. The 2004 United States Nurses Health Study indicated a prevalence of 2.3%. [34] The estimated annual incidence rate of interstitial cystitis in the US is 2.6 cases per 100,000 women.
