Its prevalence has been increasing, with alarming data in Brazil and elsewhere. Globally, Brazil ranks second in number of bariatric surgeries, but surgical treatment is a challenge for the patients and the teams that provide care for these patients. Given the above, the present study aimed to assess changes in nutritional status and identify nutritional deficiencies before and 10 years after Roux-en-Y gastric bypass. This retrospective study lasted two years and included 166 patients submitted to Roux-en-Y gastric bypass at a private clinic. The statistical analyses included the chi-square, Fisher?s, Mann-Whitney, and Wilcoxon tests, analysis of variance (ANOVA), and generalized estimating equations. The significance level was set at 5%. At the ten-year follow-up, the percentage of excess weight loss (%EWL), body mass index (BMI), and weight regain were 51.64?18.03 (p<0.0001), 32.53?4.83 kg/m2 (p<0.0001), and 41% (p<0.0001), respectively, and the lipid and blood glucose profiles had improved (p<0.0001). Iron-deficiency anemia was found in 37.5% and 45.0% of the patients who attended the 10-year follow-up based on ferritin levels <15 ug/L and <30 ug/L, respectively. The effect of time was significant for hemoglobin, ferritin, iron overload (p<0.0001), and hematocrit (p=0.0007). Vitamin D deficiency was found in 29 patients (82.86%), and high parathormone (PTH), in 13 (41.94%). The effect of time was significant for PTH (p=0.0059). In conclusion, gastric bypass was a surgical success and improved the metabolic profile. Weight regain increased over time. The nutritional outcomes were iron-deficiency anemia and vitamin D deficiency associated with secondary hyperparathyroidism. These findings reaffirm the importance of multidisciplinary care and monitoring of nutritional deficiencies for the treatment of morbid obesity. / A obesidade m?rbida considerada uma doen?a cr?nica e multifatorial, que ocasiona desordens metab?licas e aumenta o risco de morbidade, vem crescendo, com dados alarmantes no Brasil e no Mundo. O Brasil ? o segundo Pa?s que mais realiza cirurgia bari?trica, sendo o tratamento cir?rgico, um desafio para os pacientes e para as equipes envolvidas no cuidado destes pacientes. Diante do exposto, o presente trabalho teve como objetivo avaliar a evolu??o do estado nutricional e identificar as defici?ncias nutricionais no pr? e no p?s-operat?rio de pacientes submetidos ao bypass g?strico em Y-de-Roux, com 10 anos de seguimento. O estudo realizado em dois anos, com delineamento retrospectivo longitudinal, envolveu 166 pacientes submetidos ao bypass g?strico em Y-de-Roux, em uma cl?nica privada. Na an?lise estat?stica, utilizou-se os testes Qui-Quadrado, Fisher, Mann-Whitney, Anova, Wilcoxon e Equa??es de Estimativas Generalizadas. O n?vel de signific?ncia adotado foi de 5%. Os resultados deste estudo, ap?s 10 anos de seguimento, demostraram percentual de perda do excesso de peso (%PEP) de 51,64?18,03 (p<0,0001); Indice de Massa Corporal (IMC) de 32,53?4,83 kg/m2 (p<0,0001); reganho de peso de 41% (p<0,0001). O perfil lip?dico e glic?mico diminuiu ao longo de 10 anos de seguimento (p<0,0001). Dos pacientes que permaneceram no estudo at? o final de 120 meses, 37,5% e 45,0%, apresentaram diagn?stico de anemia ferropriva, considerando-se os crit?rios utilizados de ferritina <15 ug/L e ferritina <30 ug/L, respectivamente. O efeito do tempo foi significativo para a hemoglobina, ferritina e sobrecarga de ferro, (p<0,0001) e hemat?crito (p=0,0007). Em rela??o ao metabolismo do c?lcio, 82,86% (29), apresentaram n?veis de defici?ncia de vitamina D e 41,94% (13) apresentaram PTH elevado. O efeito do tempo foi significativo para o PTH (p=0,0059). Em conclus?o, pacientes submetidos ao bypass g?strico, apresentaram sucesso cir?rgico e melhora do perfil metab?lico. O reganho de peso aumentou com o tempo de seguimento. A anemia ferropriva e a defici?ncia de vitamina D, associada ao hiperparatireoidismo secund?rio, foram desfechos nutricionais encontrados Tais achados reafirmam a import?ncia do cuidado multidisciplinar e ? aten??o ?s defici?ncias nutricionais para o tratamento da obesidade m?rbida.
