Suplementação de ferro em indivíduos submetidos à derivação gástrica em Y-de-Roux

Abstract

Objective – The aim of this work was to evaluate the effects of iron supplementation and changes in the body composition in individuals submitted to Roux-en-Y gastric bypass supplemented with ferrous sulphate. Methods – Data were collected from medical records of 41 pa- tients undergoing Roux-en-Y gastric bypass, which were evaluated for body mass index (BMI), waist circumference, triceps skinfold and biochemical tests. These patients received supplementation in the form of iron glycine chelate, in dosages of 30 mg/day of elemental iron for twelve months. Results – Three and twelve months after surgery, subjects had significantly lower BMI, weight, waist circumference and triceps skinfold (P <0.001). The concentrations of total cholesterol and glucose, hemoglobin and hematocrit decreased three and twelve months significantly after surgery (P <0.001), whereas triacylglycerol dropped after three months remained until the twelfth month. Con- centrations of serum iron showed no reduction during the study period. Conclusions – Bariatric surgery reduced body fat indicators. Data suggest that supplementation with iron glycine chelate did not prevent reductions in serum hemoglobin and hematocrit, but can prevent re- ductions in serum iron concentrations in post-surgical.
