What is Hydrogen/Methane Breath Testing
Breath tests are used to identify the presence of fructose, lactose and sorbitol malabsorption as well as proximal small intestine bacterial overgrowth (SIBO). The outcome of these tests may help in the treatment and management of unwanted gut symptoms.
The extent of malabsorption of the fructose, lactose and sorbitol sugars can be determined by these tests and provides an indication of the strictness of dietary restriction required to tailor the diet more specifically to the individual.
These tests are non-invasive, painless and an effective method to confirm sugar malabsorption and proximal SIBO.
