Sleeve gastrectomy is one of the most common surgical procedures performed today for patients that undergo bariatric surgery. One of the primary reasons for morbid obesity is unhealthy eating habits and the belief that changes in those habits can ensure the success. Objectives: The investigators aimed to explore the effect of different eating habits prior to the bariatric surgery on the surgery success and on different aspect of quality of life. Design: The investigators conducted this study on patients that underwent sleeve gastrectomy as the first bariatric operation.

The investigators divided the patients into groups according to their pre-operation eating habits: binge, sweet, snack and high volume and compared different aspects of the surgery such as weight loss, BMI and distance from ideal weight. The investigators also examined the effect of the surgery on the quality of life, sexual life, physical activity, eating habits and satisfaction from the surgery by a telephonic survey that was conducted up to one year after the surgery.
