Microbiome science in the gut has focused on the study of colonic, and more frequently, fecal communities. While the upper gastrointestinal tract has significantly lower bacterial density than the colon, it still harbors a dynamic microbial community…

BACKGROUND: Considerable disparities exist in access to GI care and digestive outcomes across gender, racial, and socioeconomic groups. Notably, socially vulnerable groups have worse outcomes in IBS and IBD due to health care inequities…

Hydrogen sulfide (H2S) is a gas produced by bacteria in the gastrointestinal tract (GI) that has many unique properties and is a known gasotransmitter. Recently, a new breath test (BT) has been developed that can measure H2S in addition to other bacterial gases…

This session will explore the role of the microbiome in the pathogenesis of various functional gastrointestinal disorders. Presentations will highlight the complex interactions between the gut microbiota and brain health, including their impact on cognitive functions, anxiety, and depression…
