Summary:Aim: The aim of this study was to assess the prevalence of hypovitaminosis D in candidates to bariatric surgery (BS) and its relationship with risk factors and components of the metabolic syndrome. Material and methods: Clinical, anthropometric and biochemical parameters were measured in 56 Caucasian patients included in a protocol of BS between January and June 2014. Patients were stratified into three groups according to their vitamin D status: sufficiency (≥ 40 ng/ml), insufficiency (40-20 ng/ml) and deficiency (< 20 ng/ml). Results: Data showed vitamin D deficiency in 75% of patients. These patients had greater BMI (p = 0.006) and lower PTH concentrations in plasma (p = 0.045). In addition, there were more patients with diabetes mellitus type 2 (DM2) and dyslipidemia (DLPM) in the group with 25 (OH) D < 20 ng/ml levels. Another finding was that 25(OH) D levels were observed to be negatively correlated with fat mass (r = -0.504; p = 0.009), BMI (r = -0.394; p = 0.046) and hypertension (r = -0.637; p = 0.001). Conclusion: We conclude that vitamin D deficiency is extremely common among candidates to BS, who are associated with DM2 and DLPM. Although there are limited data regarding the best treatment for low Vitamin D status in BS candidate patients, screening for vitamin D deficiency should be regularly performed in cases of morbid obesity.
