Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 and above who are either self-reported lactose intolerant or lactose tolerant without gastrointestinal disorders.
✕Probably not a fit
Patients with gastrointestinal disorders or those who experience adverse reactions to lactose or sucrose may not benefit from this study.

What this trial studies
This interventional study aims to validate the Smart Underwear device's ability to detect lactose intolerance by comparing its results with self-reported symptoms in adult participants. Participants will be divided into lactose-tolerant and lactose-intolerant groups and will consume both lactose and sucrose to assess the device's effectiveness in measuring flatus events and microbiome activity. The study involves a low-fiber/low-FODMAP diet, food logging, and wearing the device for 8 hours daily over three days. The goal is to determine if the device can reliably differentiate responses to lactose versus sucrose consumption.
Why it matters
Potential benefit: If successful, this study could provide a non-invasive method for diagnosing lactose intolerance.
How similar studies have gone: While the approach of using wearable technology for gastrointestinal monitoring is emerging, this specific application of the Smart Underwear device is novel and has not been extensively tested in prior studies.
