Levels and Supplement Intake in Pregnancy after

" These authors are joint first authors on this work. Background: Studies report frequent micronutrient deficiencies after bariatric surgery, but less is known about micronutrient levels of pregnant women after bariatric surgery. Objective: To prospectively evaluate micronutrient levels and supplement intake in pregnancy following bariatric surgery. Design: A multicenter prospective cohort study including women with restrictive or malabsorptive types of bariatric surgery. Nutritional deficiencies, together with supplement intake, were screened during pregnancy. Results: The total population included 18 women in the restrictive and 31 in the malabsorptive group. Most micronutrients were depleted and declined significantly during pregnancy. The proportion of women with low vitamin A and B-1 levels increased to respectively 58 and 17 % at delivery (P50.005 and 0.002). The proportion of women with vitamin D deficiency decreased from 14 % at trimester 1 t
