[Body weight evolution and classification of body weight in relation to the results of bariatric surgery: roux-en-Y gastric bypass].

Objective: The objective of this study was to assess the evolution and classification of body weight in relation to the results of bariatric surgery in women who underwent the procedure more than two years ago.

Subjects And Method: A total of 141 women underwent banded Roux-en-Y gastric bypass (RYGB). The participants were divided according to the time elapsed since surgery and the percentage of excess weight lost (%EWL): < 50; 50 upper and lower left quadrants 75; and > 75.

Results: The women in the group with %EWL < 50 (15.6%) remained obese, while those with %EWL > 75 (36.2%) ranged from normal to pre-obese and presented lower late weight gain than the women in the other groups.

Conclusion: Weight evolution two or more years after surgery showed the expected reductions, with some individuals responding better to surgery than others. This shows that it is necessary to monitor, investigate and intervene to obtain the desired results.
