BACKGROUND: We evaluated dietary intakes, body composition, micronutrient deficiency, and response to micronutrient supplementation in 47 patients before and for 6 months after laparoscopic sleeve gastrectomy (LSG).
METHODS: Before, 3, and 6 months after LSG, we measured dietary intakes with food-frequency questionnaires, body composition with bioimpedance analysis (BIA) and bioelectrical vector analysis (BIVA), and plasma concentrations of iron, Zn, water-, and lipo-soluble vitamins.
RESULTS: After LSG, energy intake significantly decreased and patients lost weight, fat mass, and free-fat mass. BIVA showed a substantial loss of soft tissue body cell mass (BCM) with no change in hydration. Before surgery, 15 % of patients were iron deficient, 30 % had low levels of zinc and/or water-soluble vitamins, and 32 % of vitamin 25(OH)-D3. We treated iron deficiency with ferrous sulfate, isolated folate deficiency with N5-methyiltetrahydrofolate-Ca-pentahydrate, and deficiencies in vitamin B1, B12, or Zn, with or without concomitant folate deficiency, with multivitamin. No supplementation was given to vitamin 25(OH)-D3 deficient patients. At first follow-up, 7 % of patients developed new deficiencies in iron, 7 % in folic acid (n = 3), and 36 % in water-soluble vitamins and/or zinc whereas no new deficit in vitamin 25(OH)-D3 occurred. At final follow-up, deficiencies were corrected in all patients treated with either iron or folate but only in 32 % of those receiving multivitamin. Vitamin 25(OH)-D3 deficiency was corrected in 73 % of patients even though these patients were not supplemented.
CONCLUSION: LSG-induced weight loss is accompanied by a decrease in BCM with no body fluid alterations. Deficiencies in water-soluble vitamins and Zn respond poorly to multivitamin supplementation.
