Abstrakt:	Aim: to compare the impact of Roux's Y Gastric Bypass (RYGB) and Sleeve Gastrectomy (SG) techniques on body weight reduction over 1 and 5 years after bariatric surgery in obese patients in the state of Paraná. Methods: longitudinal and retrospective study, conducted between January 2010 and December 2013, with 737 patients of both sexes submitted to RYGB or SG and evaluated in the preoperative, 1 and 5 years after bariatric surgery (BS). Age, height, body weight, Body Mass Index (BMI), biochemical and pressure parameters were recorded. Results: of the total of patients, men represented lower frequency, were slightly older, with higher body weight, BMI and worse metabolic and pressure conditions than women in pre-BS (p<0.05). Regardless of sex, RYGB and SG were effective in promoting body weight reduction and BMI in 1 and 5 years after BS; the RYGB technique had greater impact on these variables in both sexes (p<0.05). The highest percentage of lost weight was observed in women who underwent the RYGB technique in the first year after BS. Five years after BS, the RYGB technique promoted a higher rate of body weight reduction in men and women compared to the SG technique (p<0.05). Conclusion: regardless of sex, the RYGB technique promotes a higher degree of body weight reduction and BMI over time compared to the SG; having its biggest impacts in the 1 year after BS, especially in women.
