Using breath tests in gastroenterology: Clear and reliable practitioner guide in 2025.

Quick Summary

This is a review article describing how breath tests work in gastroenterology and their current clinical uses in 2025. Breath tests detect gases produced by gut bacteria or digestive enzymes, helping doctors diagnose conditions like carbohydrate malabsorption and bacterial overgrowth without invasive procedures.

What Was Studied

This is a review article summarizing the current state of breath testing in gastroenterology practice. It covers how breath tests have evolved from basic to quantitative analyses and their applications for diagnosing various gastrointestinal disorders.

How the Study Was Conducted
