Resumo |
Objective: The objective of this study was to determine whether constant daily vitamin supplementation would be sufficient to prevent possible vitamin deficiencies in obese patients undergoing bariatric surgery. Methods: The study was conducted on 58 men and women (mean age 41 +/- 10 y) who underwent Roux-en-Y gastric bypass RYGB and were assessed preoperatively and at 3, 6, and 12 mo after surgery. During the postoperative period, the patients received a multivitamin-mineral supplement on a daily basis. Results: Serum beta-carotene and vitamin C were lower starting from the third postoperative month and continued to be low after 12 mo, and vitamin A was decreased by the sixth month and increased by 12 mo. Vitamin B12 levels were stable up to 6 mo but were decreased by 12 mo. Folic acid levels increased from the third month and remained higher throughout follow-up. One year after surgery there were 19% and 21% increases in the number of patients with vitamin A and vitamin C deficiency, respectively, and a 4% decreased of patients with folic acid deficiency. Conclusion: Weight loss and improvement in patients' general condition followed surgery, but serum levels of some vitamins were decreased despite the use of a vitamin-mineral supplement. These patients need continuous follow-up and individualized prescription of supplementation after the surgical procedure to prevent and treat vitamin deficiencies. (C) 2012 Elsevier Inc.
