Treatment for Vitamin D Deficiency Prior to Bariatric Surgery: a Prospective Cohort Study

Abstract

Background

Since obesity increases vitamin D deficiency (VDD) risk, bariatric surgery candidates are high-risk. 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.
