Sucrose Malabsorption Breath Test

About the Test

This test is used to help diagnose sucrose malabsorption. Sucrose malabsorption may occur when the enzyme needed to break down sucrose, or table sugar, is not present. The lack of the enzyme allows bacteria normally found in the digestive system to produce hydrogen and/or methane gas which can cause many gastrointestinal symptoms such as bloating, diarrhea, and flatulence.
