Clinical outcomes following pre-and post-operative vitamin D supplementation in Roux-en-Y gastric bypass patients

Bariatric surgery is associated with risks for micronutrient deficiencies. For example, hypovitaminosis D (25(OH)D ≤30ng/mL) has been reported in obese individuals and patients who received Roux-en-Y gastric bypass (RYGB). Investigations on incidence of hypovitaminosis D in patients undergoing bariatric surgery in the Pacific Northwest are limited. The primary aim of this study was to identify the incidence of hypovitaminosis D in patients prior to RYGB. The relationship between 25(OH)D status and patient characteristics (age, gender, ethnicity, BMI, comorbidities) was analyzed. The secondary aim was to analyze longitudinal change in 25(OH)D concentration 1 year post-operatively.
