Previously, we documented 71.4 % VDD at our center. Objectives: To investigate diagnosis and treatment for VDD in our bariatric candidates. Methods: 25(OH)D, if pending, and supplementation (form, dosing, frequency) were prospectively documented in 265 candidates. Results: Candidates were 83.0 % female, 48.9 % white, age 43 ± 13 years and BMI 46.3 ± 10.5 kg/m2. 25(OH)D was available for 18.5 %: 35.7 % VDD 39.3 % insufficiency. VDD history did not differ by demographics or procedure, as with those tested versus not. Conclusion: VDD testing was lower than clinically-indicated. Of those tested, 35.7 % were deficient and 39.3 % insufficient. We previously reported higher rates: 71.4 % deficiency, 92.9 % insufficiency. Thus, many candidates are untested but high-risk.
