Background: Sleeve gastrectomy (SG) has effective results on weight loss, which should result from fat mass loss and efforts should be made to preserve lean mass. Few studies have evaluated body composition (BC) changes after SG for periods >2 years.
Objective: To investigate the impact of SG on weight and BC, comparing by gender.
Materials and methods: Retrospectively, databases of patients who underwent SG between 2011 and 2013 were analyzed. Data was obtained before and 1, 2 and 3 years after SG. BC was measured by bioelectrical impedance.
Results: Fifty-five females, mean age 42.11±10 years, mean body mass index (BMI) 44.59±4.9 Kg/m2 and 11 males, mean age 39.55±10.9 years, mean BMI 44.66±5.4 Kg/m2 were included. One year after SG, males had lost 36% of weight, 67% of fat mass and 18% of lean mass. In females, 1 year after SG, weight decreased 32%, fat mass 52% and lean mass 12%. Two and 3 years after surgery, males had lost 33% and 30% of weight, 59% and 53% of fat mass and 20% and 19% of lean mass, respectively. In females, 2 and 3 years after surgery weight decreased 33% and 30%, fat mass 52% and 48% and lean mass by 14% and 13%, respectively. Males presented the lowest weight and fat mass 1 year after surgery; females had the lowest weight and fat mass 2 years after SG.
Conclusion: Despite both genders show a weight loss of 30% 3 years after SG, males initially lose more weight that is regained after the first year. Males also present a greater loss of lean mass. Our results highlight the need to develop strategies to avoid weight regain, which seems to start 1 and 2 years after SG, respectively for males and females. Efforts should be also made in order to avoid lean mass loss.
