Objective
The aim of this study was to determine changes in lean body mass after bariatric surgery.
Methods
This retrospective study reviewed 17 medical records of obese women who underwent banded Roux-en-Y gastric bypass. The medical records contained data collected immediately before and 1, 3, 6 and 12 months after surgery. The data included age, weight, height and lean and fat body mass determined by bioelectrical impedance analysis.
Results
The mean age of the patients was 43.1 years (SD=7.7). Body mass index decreased significantly within 12 months of the surgery, going from 51.2 (40.2-74.1) to 33.7 (24.8-53.4)kg/m2, as did fat body mass, going from 67.5 (51.2-67.4) to 32.1 (16.4-61.9)kg. In the first month after surgery, lean body mass decreased from M=65.3 (SD=7.6) to M=59.7 (SD=8.1kg), representing a decrease of 8.5%. Lean body mass remained constant after this period.
Conclusion
Loss of lean body mass may indicate a change in protein metabolism immediately after bariatric surgery, which may result in an unfavorable clinical and nutritional course.
