Summary

This study tested a smart underwear device to see if it can detect lactose intolerance by measuring gas events after drinking lactose. 37 adults (some lactose tolerant, some intolerant) wore the device and consumed both lactose and a placebo (sucrose) on separate days. The goal was to see if the device's readings matched their reported symptoms, offering a new way to diagnose lactose intolerance.
