This is a prospective, single-arm observational diagnostic study without therapeutic intervention or control arm. Participants undergo diagnostic assessment for SIBO including lactulose hydrogen/methane breath testing and gastroduodenoscopy with collection of small intestinal luminal aspirate, mucus and mucosal biopsies, as well as stool, saliva and venous blood sampling. Gastroduodenoscopy is performed only when clinically indicated and is not performed solely for study purposes.
