Do diet and hormones affect IC flares?

Yes—both diet and hormonal shifts can influence interstitial cystitis (IC) flares for many patients. Commonly reported triggers include acidic foods, caffeine, alcohol, and artificial sweeteners, though triggers are highly individual and not everyone reacts the same way.

Many people also notice symptoms worsen in the days leading up to a period, when hormonal and inflammatory changes can make the bladder more sensitive. A practical way to identify your personal triggers is a short, structured elimination period followed by careful reintroduction, rather than broad long-term restriction. If your flares are cyclical, our team can help you evaluate patterns and build a plan that supports your bladder while we also look for overlapping pelvic conditions that can mimic or worsen IC symptoms.
