Abstract
BACKGROUND: Nutritional deficiencies occur after weight loss surgery. Despite knowledge of nutritional risk, there is little uniformity of postoperative vitamin and mineral supplementation. The objective of this study was to evaluate a composite supplement based on the clinical practice guidelines proposed in 2008 regarding vitamin and mineral supplementation after Roux-en-Y gastric bypass. The composite included iron (Fe) and calcium as well. METHODS: A retrospective chart review of 309 patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB) was evaluated for the development of deficiencies in iron and vitamins A, B1, B12, and D. Patients were instructed to take a custom vitamin and mineral supplement that was based on society-approved guidelines. The clinical practice guidelines were modified to include 1600 international units (IU) of vitamin D3 instead of the recommended 800 IU. RESULTS: The compliant patients' deficiency rates were significantly lower than those of the noncompliant patients for iron (p = 0.001), vitamin A (p = 0.01), vitamin B12 (p ≈ 0.02), and vitamin D (p < 0.0001). Women's menstrual status did not significantly influence the development of iron deficiency. CONCLUSIONS: Use of a composite based on guidelines proposed by the AACE, TOS, and the ASMBS appears to be effective for preventing iron and vitamins A, B1, B12, and D deficiencies in the LRYGB patients during the first postoperative year. Separation of calcium and Fe does not need to be mandatory. Even with simplification, compliance is far from universal.
