Can Diet or Hydrogen Water Help Interstitial Cystitis? A Review

**TL;DR:** When people with painful bladder syndrome tried cutting out foods that bothered them personally, their symptoms got better—but other popular diet approaches like anti-inflammatory eating didn't help much. Scientists say we need bigger, longer studies to figure out exactly which diets actually work.

Hydrogen-rich water showed no significant improvement in any symptom measures for interstitial cystitis/bladder pain syndrome in the available studies.

This systematic review examined how different dietary changes affect interstitial cystitis/bladder pain syndrome (IC/BPS), a condition that causes chronic bladder pain and urgency. Researchers reviewed four small studies and found that personalized elimination diets (removing foods that trigger symptoms) significantly reduced pain and symptom scores over 12 months, while anti-inflammatory diets and hydrogen-rich water showed no clear benefit.

While this review found that hydrogen-rich water did not help IC/BPS symptoms in the small trials examined, the overall evidence base for all dietary interventions in this condition is very limited. Anyone considering dietary changes for IC/BPS should work with a healthcare provider, as the strongest evidence currently supports individualized elimination diets rather than hydrogen water or general anti-inflammatory approaches.

Introduction and hypothesis: Interstitial cystitis/bladder pain syndrome (IC/BPS) is prevalent and disrupts daily life. Dietary modification is commonly recommended, but evidence is fragmented. We systematically compared dietary interventions; we hypothesized that individualized elimination may…
