FAQs
1What is Hydrogen Breath Test?
The Hydrogen Breath Test is a test that uses measurement of hydrogen in exhaled breath to diagnose various conditions that cause gastrointestinal symptoms.
In normal condition, only colonic anaerobic bacteria are capable of producing hydrogen when undigested food (particularly sugars and carbohydrates) reaches to colon which is in small amount but conditions which causes indigestion leads to more undigested food to reach colon and thus producing large amount of hydrogen.
In conditions like SIBO (Small Intestinal bacterial Overgrowth) where colonic bacteria move back into small intestine and produces hydrogen from food those has not been completely traversed small intestine to be fully digested and absorbed.
These hydrogen produced by colonic and small intestinal bacteria enters into blood flowing through the wall of intestine and reaches lungs where it is exhaled in the breath where it can be measured.
