Can food allergies cause recurrent UTIs?
There is no strong evidence that food allergies directly cause recurrent UTIs. However, certain foods can irritate the bladder and worsen UTI-like symptoms in sensitive individuals.
Detailed Medical Explanation
Food allergies do not cause infections, but foods like caffeine, alcohol, citrus, and artificial sweeteners may trigger bladder irritation in some people. This is more relevant in interstitial cystitis. See NHS: UTI facts.
