TY - JOUR TI - Serum 25(OH) Vitamin D Levels in Severely Obese Patients Evaluated Before Bariatric Surgery AB - Objective: Obesity is a risk factor for vitamin D deficiency,which is reported to be detected differently in each population. This study aimed to evaluate the 25(OH) vitamin D(25(OH)D) levels, intact parathormone (iPTH) levels, andtheir relationship with body mass index (BMI) in obese patients, screened prior to bariatric surgery. Material and Methods: This retrospective study comprised of 1.082 obesepatients (41±10 years, female/male: 823/259) who werecandidates for bariatric surgery. BMI, waist circumference(WC), serum 25(OH)D, iPTH, calcium, phosphorus values ofthese patients were recorded from patient files. Results:BMI, WC, iPTH, and 25(OH)D levels were 48±8.9 kg/m²,128±11.9 cm, 64±36 pg/mL, and 15±18 ng/mL, respectively. Mean 25(OH)D level of 79.1% of the patients belongedto the deficiency range. Very low 25(OH) vitamin D levels(<10 ng/mL) were witnessed among 40.9% (443/1.082) ofthe study group. Female obese subjects possessed significantly lower serum 25(OH)D levels as compared to maleobese patients. Significant negative correlations were perceived between 25(OH)D levels and iPTH (r=-0.34,p<0.0001), BMI (r=-0.20, p<0.0001), and waist circumferences (r=-0.14, p=0.002) in the whole group. Multivariateanalysis indicated that BMI to be an independent risk factorfor vitamin D deficiency. Conclusion: A high rate of vitaminD deficiency was documented in our morbidly obese patientswho were candidates for bariatric surgery. BMI is a determinant of 25(OH)D levels. It is essential to screen for vitaminD deficiency and possible osteomalacia among the candidates for bariatric surgery of obese patients and should betreated appropriately before bariatric surgery.
