Detect Fructose Malabsorption | Shipping Nationwide

Overview

The Fructose Intolerance Breath Test is a non-invasive diagnostic tool used to detect fructose malabsorption, a condition where the small intestine has difficulty absorbing fructose (a sugar found naturally in fruits, honey, and some vegetables, as well as in many processed foods). This malabsorption leads to excess fructose in the intestines, which ferments and causes symptoms similar to those of irritable bowel syndrome (IBS), including bloating, gas, abdominal pain, diarrhea, and constipation.

Who Should Get Tested?

This test is ideal for individuals who:

  • Experience digestive symptoms after consuming fructose-containing foods
  • Have symptoms consistent with IBS or other functional gut disorders
  • Want to differentiate between fructose intolerance and other causes of digestive distress
  • Are following dietary changes but want a clear diagnosis to guide treatment
  • Have unexplained bloating, cramps, or irregular bowel movements

What This Test Measures

  • Levels of hydrogen and methane gases in the breath after fructose ingestion
  • Elevated gases indicate bacterial fermentation of unabsorbed fructose in the small intestine

What You’ll Get with Your Report

  • Graphs showing hydrogen and methane gas production over time
  • Identification of abnormal patterns consistent with fructose malabsorption
  • Clear interpretation to help guide dietary and clinical decisions
  • Insights useful for practitioners to tailor treatment strategies, including diet and supplementation
