ClinConnect Summary
This clinical trial is looking into the causes of chronic gastrointestinal (GI) symptoms experienced by veterans who served in the Gulf War. Many veterans report ongoing issues like abdominal pain, diarrhea, and bloating that began during their service. Unfortunately, there are currently no specific treatments available for these problems, which significantly affect the health and well-being of many veterans. The goal of this study is to test a new treatment that could help improve these symptoms and, ultimately, enhance the quality of life for those affected.
To be eligible for this study, participants must be veterans aged 18 to 65 who have Gulf War Illness and have experienced chronic GI symptoms since their deployment in the Persian Gulf. They also need to have a specific test result indicating increased intestinal permeability, meaning their gut may not be functioning properly. Participants can expect to work closely with the research team and will be monitored throughout the trial. Importantly, this study aims to provide valuable insights and potential new solutions for the many veterans suffering from these distressing symptoms.
