Objective: The aim of our study was to evaluate the serum micronutrient changes in patients with morbid obesity after LSG or LBPD/DS. Methods: We retrospectively reviewed 39 patients diagnosed with morbid obesity who had LSG or LBPD/DS between June 2001 and June 2005. All patients routinely received mineral and vitamin supplements. Serum Iron (Fe), Calcium (Ca), Zinc (Zn), Selenium (Se), Vitamin A (Vit A), 25-hydroxy Vitamin D3 (Vit D), VitaminB12 (VitB12) and Parathormone (PTH) were measured at 6, 12 and 24 months after surgery. Results: Of 39 morbid obese patients, 20 had LSG (11 males and 9 females, mean age of 44 years) and 19 had LBPD/DS (7 males and 12 females, mean age of 42 years). The mean BMI prior to LSG, LBPD/DS was 62.73+/-8.62 kg/m2 and 50.01+/-7.68 kg/m2 respectively. The mean BMI after LSG and LBPD/DS was 47.92+/-9.00 kg/m2 and 29.6747.92+/-4.65 kg/m2 respectively. The mean BMI of all patients was decreased (P
