Introduction
H
2
is generated in the intestinal lumen by bacterial action on carbohydrates in the small or large
intestine. Once the resultant H
2
is diffused into the bloodstream it is transported to the alveoli and
then can be detected in expiratory air. Levitt
1
demonstrated the correlation between intestinal
lumen H
2
production and H
2
excretion in expiratory air. Accurate measurement of H
2
in parts per
million (ppm) in expiratory air reveals intolerance and/or malabsorption of carbohydrates; or
bacterial overgrowth.
Operation of the monitor is straightforward. A D-piece™ sampling system enables end-expired
breath to be sampled easily and hygienically, using single-use disposable SteriBreath™ mouthpieces
and disposable face masks.
The Gastro
+
™ can be used to aid in the diagnosis of the following disorders:
• Carbohydrate intolerance
• Carbohydrate malabsorption
• Intestinal bacterial overgrowth
• Investigation of intestinal transit time
