H2 breath tests during diarrhea.
The peak rise in breath hydrogen and the volume of excess pulmonary excretion of hydrogen in response to a 10 g dose of the non-abosorbable disaccharide, lactulose, was significantly lower in children with active gastroenteritis and diarrhea than in nondiarrheal controls. Thus, despite the fact that the H2 breath test is a convenient, noninvasive technology for use in children, it cannot be recommended for measuring carbohydrate malabsorption in individuals with active, on-going episodes of diarrhea.
