A 2021 questionnaire posted on an IC website asked if people had experienced a miscarriage. 76% of the 193 respondents, who had an IC diagnosis, had experienced a miscarriage.
78% of the respondents reported experiencing significant stress. Acute stress may worsen IC symptoms by stimulating immune cells in the bladder and uterus, which could link to miscarriage.
IC may lead to a higher risk of certain pregnancy complications, including preeclampsia and preterm birth.
