Title: Smart Underwear: A Novel Wearable for Long-Term Monitoring of Gut Microbial Gas Production via Flatus

 

Speaker: Brantley Hall, PhD

 

Format: In-Person

 

Objectives:

1. Describe the role of hydrogen as a terminal electron sink in gut microbial fermentation, and explain why measuring H₂ in vivo provides a readout of electron flow through the reductive side of gut microbial metabolism.

 

2. Compare the limitations of current methods for measuring gut microbial gas production (rectal tubes, hydrogen breath testing, imaging, patient-reported outcomes) against continuous longitudinal monitoring with the Smart Underwear.

 

3. Interpret data from the Smart Underwear studies showing discordance between subjective symptom perception and objective flatus measurement, and explain how objective measurement enables detection of carbohydrate malabsorption.
