Using Breath Tests to Study Gut Sulfur Changes During Dietary Therapy (NCT07640659)
Sulfur on the Breath: Using Breath Biomarkers to Monitor Gut Microbial Sulfur Metabolism During Elemental and Reduced Sulfur Dietary Therapy
🩺 Plain-English Summary (8th-Grade Level)
This study aims to test whether a short liquid-based diet, followed by a low-sulfur eating plan, is safe, manageable, and helpful for people with mild to moderate ulcerative colitis. Investigators want to see if this approach can improve gut health, lower inflammation, and reduce symptoms. Investigators will also test breath samples as an easy, non-invasive way to track gut bacteria activity and disease changes. Investigators believe this diet plan can reduce harmful gut bacteria that produce irritating sulfur compounds, leading to better gut health and measurable improvements that can be detected through breath testing.
