Summary
Diagnosing lactose malabsorption can be challenging due to varied testing methods. Improving the hydrogen breath test by extending its duration and measuring transit time enhances accuracy for this common digestive issue.
Area of Science:
- Gastroenterology
- Digestive Physiology
Background:
- Lactose malabsorption is prevalent, yet diagnostic methods lack standardization.
- Accurate diagnosis is crucial in gastroenterological practice.
Purpose of the Study:
- To compare commonly used lactose malabsorption tests.
- To recommend improvements for the most utilized diagnostic method.
Main Methods:
- Review and comparison of various lactose malabsorption tests.
- Focus on the hydrogen breath test and oro-cecal transit time measurement.
Main Results:
- No single 'gold standard' test for lactose malabsorption exists.
- The hydrogen breath test is the most frequently used method.
- Prolonging the hydrogen breath test to 4 hours and measuring oro-cecal transit time can improve accuracy.
Conclusions:
- Standardization of lactose malabsorption testing is needed.
- Optimizing the hydrogen breath test offers a more accurate diagnostic approach.
