GWI causes a range of pain, fatigue, gastrointestinal, skin, neurologic, and respiratory symptoms. New treatments to reduce GWI-associated morbidity are critically needed. Research suggests a role for the gastrointestinal microbiome in mediating health, including through impacting metabolism and immunity. The disruption of this microbiome plays a role in multiple diseases, and preliminary data suggest that Veterans with GWI have altered gut microbiota.
