title: [Evolution of the intake and nutritional status of zinc, iron and copper in women undergoing bariatric surgery until the second year after surgery].
abstract: BACKGROUND
  Bariatric surgery allows a significant reduction in weight and improvement of comorbidities associated with obesity in the long term, but it can also adversely affect the nutritional status of some micronutrients.
  
  
  OBJECTIVE
  To evaluate changes in intake and parameters of nutritional status of zinc, iron and copper in patients undergoing Roux-en-Y gastric bypass (GBP) or sleeve gastrectomy (SG), until the second postoperative year.
  
  
  METHODS
  We prospectively studied 45 women undergoing GBP or SG (mean age 35.2 ± 8.4 years, mean BMI 39.8 ± 4.0 kg/m²), every 6 months We measured intake and status indications nutritional zinc, iron and copper, and annually evaluated body composition. The contribution of minerals through supplements represented twice the recommended intake for a healthy woman in patients undergoing GT and three times for GBP.
  
  
  RESULTS
  20 women underwent GBP and 25 SG. In both groups there was a significant reduction in weight and body fat percentage, which was maintained until the second postoperative year. Women who have had a greater commitment GBP nutritional status of zinc, iron and copper, that patients undergoing SG.
  
  
  CONCLUSIONS
  Gastric bypass Roux-Y produces a greater commitment of nutritional status of zinc, iron and copper sleeve gastrectomy. It should evaluate whether administration of supplementation fractional improve the absorption of these nutrients.
