Patients undergoing Roux-en-Y gastric bypass experienced a 31% reduction in BMI and decreased nutritional deficiency rates for vitamin D and B12 after 12 months.
Does dietary education and multivitamin supplementation improve nutritional status and BMI in patients undergoing Roux-en-Y gastric bypass surgery?
Dietary education and multivitamin supplementation after RYGB surgery are associated with significant improvements in BMI and reductions in specific nutritional deficiencies at 12 months.

Abstract Background Few studies have evaluated the effects of Roux-en-Y Gastric Bypass (RYGB) and the consequential gastric restrictions and changes in nutrient absorption on the nutritional profile of bariatric patients. This retrospective study aims to evaluate the impact of dietary education and the benefits of supplementation in patients after RYGB during the twelve-month postoperative period. Methods The retrospective cohort study was conducted using data from the Obesity and Metabolic Syndrome Center of the University Hospital of Brazil. Clinical records of patients who underwent RYGB surgery between September 2018 and January 2019 were analyzed before and after surgery, including patient variables such as age, gender, follow-up time, body mass index (BMI), and biochemical tests. All patients evaluated received dietary guidance and reinforcement of the importance of maintaining multivitamin supplementation. Results Patients who underwent RYGB surgery showed a 31% reduction in BMI 12 months after the surgery. Moreover, the percentage of patients with nutritional deficiency for vitamin D (P 0.001), vitamin B12 (P = 0.0154), iron (P = 0.057), and folic acid (P = 0.424) decreased to 11.9%, 8.8%, 3.9%, and 6.9%, respectively. Conclusion Nutritional deficiencies are common after RYGB surgery, but this study demonstrated an improvement in the nutritional status of RYGB patients during the twelve-month postoperative period. This suggests that supplementation may be an effective means of managing nutritional deficits. Additional studies need to be conducted to clarify the effect of these findings on RYGB outcomes.
