Introduction: Obese patients have better glycemic control and/or Type 2 diabetes mellitus (T2DM) remission after bariatric surgery.

Objectives: To evaluate body composition in obese patients after Roux-en-Y Gastric Bypass surgery (RYGB).

Methods: Anthropometric measurements, subcutaneous adipose tissue (SAT) and muscle thickness of both thighs were determined, 30, 60, 90 and 180 days after surgery (N:19) and ten years after RYGB (N:7). During these periods, patients were evaluated by ultrasound in transverse plane to determine the thickness of SAT and muscle of the lower limbs.

Results: They were 6 female and 1 male with 51(±6.0years) of age. Six of them had initially T2DM, with remission after surgery. The baseline Body Mass Index was 43(±8.0kg/m2), and after 10 years of RYGB was 31(±5.5kg/m2). The right and left muscle thickness in baseline were, respectively, 3.0(±0.6 cm) and 3.0(±0.6 cm), after 10 years were 2.1(±0.6 cm) and 2.0(±0,6 cm).The right and left SAT thickness were, respectively, 2.0(±0.5 cm) and 1.6(±0.6 cm), at baseline and after 10 years 0.9(±0.5cm) and 0,5(±0.2 cm).The reduction of muscle and SAT thickness and weight 10 years after RYGB was significant compared to the baseline.

Conclusion: After 10 years of RYGB, we found maintenance of weight loss, reduction of muscle and fat thickness and remission of T2DM.
