This study aims to determine, in obese subjects, the antisecretory effect of a single dose of placebo, rabeprazole 20 mg and omeprazole 20 mg using 24h gastric pH monitoring, in a prospective, monocentre, randomized manner. Monitorings are separated between 6 and10 days. The main outcome criteria of analysis is the percentage of time with gastric pH above 3 during 24hours.
