Use of pulmonary hydrogen (H 2 ) measurements to quantitate carbohydrate absorption. Study of partially gastrectomized patients.

A technique was developed to quantitate the absorption of ingested carbohydrate by means of continuous measurements of pulmonary H(2) excretion. This technique is based on the observation that H(2) is produced in the colon when carbohydrate is fermented by colonic bacteria, and this H(2) is then exc... View More
