An important option, for patients that diet and exercise are insufficient, is the Laparoscopic Gastric Bypass (R-YGB) surgery. In the first step, volume of the stomach is reduced to a volume of about 30-50 cc to ensure the feeling of fullness with smaller portions. In the second step, early contact of a portion of the small intestines is eliminated and absorption is partially reduced to ensure the excretion of the high-calorie foods taken in by the patients.
