What this trial studies
This study investigates the chronic gastrointestinal symptoms experienced by veterans with Gulf War Illness, focusing on the potential benefits of oral glutamine supplementation. The research aims to understand the mechanisms behind these symptoms, which include abdominal pain, diarrhea, and bloating, and how glutamine may restore intestinal permeability. By conducting this trial, the investigators hope to provide a novel treatment option for veterans suffering from these debilitating symptoms, which currently lack effective therapies. The study will involve veterans aged 18-65 who meet specific eligibility criteria related to their gastrointestinal health.
Why it matters
Potential benefit: If successful, this study could provide a new treatment option for veterans suffering from chronic gastrointestinal symptoms related to Gulf War Illness.
How similar studies have gone: Previous studies have shown promising results with glutamine supplementation in similar gastrointestinal conditions, suggesting potential success for this approach.
