Study Overview
Brief Summary
The objective of this research is to determine the incidence of microbial overgrowth of the small intestine before and after a gastric bypass. For this purpose, the study is based on the analysis of the expired hydrogen H2 with gas chromatography before surgery and at 1, 3, 6, 12, 18 and 24 months.
