A Potential New Biomarker
Session co-moderator Kyle Staller, MD, MPH, director of the Gastrointestinal Motility Laboratory at Mass General and associate professor of medicine at Harvard Medical School in Boston, Massachusetts, said in an interview that if validated, these findings provide hope for better directing low FODMAP diets to those patients who may benefit.

There are some patients who may or may not respond to a FODMAP diet, for reasons we don’t yet know, possibly related to fermentation of gas, and it’s helpful to know before starting treatment, he said. It may help us with more of “a precision medicine approach before we really torture people with diets that can be very difficult to adhere to.”
Staller, who was not involved in the study, added that, “People tend to really focus on small intestinal bacteria overgrowth when it comes to hydrogen and methane production, but in reality, this is really a very agile day-to-day, meal-to-meal responsiveness.
“It’s a different paradigm,” he continued. “I’d also like to see more data as to why we see the diurnal rhythm” and whether potential factors such as intestinal transit times are playing a role.
