Abstract

BACKGROUND: Bariatric surgery is widely performed to improve obesity-related disorders, but can lead to nutrient deficiencies. In this study we examined serum trace element concentrations before and after bariatric surgery.

METHODS: We obtained serum trace element concentrations by inductively coupled plasma-mass spectrometry (ICP-MS) method in 437 patients (82% women, median preoperative body-mass index 46.7kg/m(2) [interquartile range 42-51]) undergoing either gastric banding (22.7%), sleeve gastrectomy (20.1%), or gastric bypass (57.3%) procedures. Trace element data were available for patients preoperatively (n=44); and 3 (n=208), 6 (n=174), 12 (n=122), 18 (n=39), 24 (n=44) and 36 months (n=14) post-operatively. All patients were recommended to take a multivitamin-mineral supplement after surgery.

RESULTS: Copper deficiency was found in 2% of patients before surgery; and after surgery deficiency rates ranged from 0 to 5% with no significant change in median concentrations during follow-up (p=0.68). Selenium deficiency was reported in 2% of patients before surgery; and after surgery deficiency rates ranged from 11 to 15% with a near-significant change in median concentrations (p=0.056). Zinc deficiency was reported in 7% before surgery; and after surgery deficiency rates ranged from 7 to 15% with no significant change in median concentrations (p=0.39).

CONCLUSIONS: In bariatric surgery patients recommended to take multivitamin-mineral supplements, serum copper, zinc and selenium concentrations were mostly stable during the first years after bariatric surgery. There was a possible tendency for selenium concentrations to decline during the early postoperative period.
