Background: Patients who undergo sleeve gastrectomy are at risk for micronutrient deficiencies. The aim of this study was to investigate the changes of serum 25OH-vitaminD level in obese patients after sleeve gastrectomy.
Methods: This retrospective study consisted of 952 patients (682 female and 272 male) who underwent bariatric surgery by a surgical team in Shiraz Mother and Child Hospital. Serum levels of 25OH-vitaminD before and three months after the surgery was evaluated. Results: the results indicated that the mean of serum 25OH-vitaminD level in women ranged from 15.65±1.2 to 24.6±1.98 (P value=0.05) and in men from 15.65±1.2 to 26.72±2.33 (P value=0.02).
Conclusions: Our findings shows that bariatric surgery contributed to improve vitamin D deficiency after 3 months in obese patients undergoing sleeve gastrectomy, which indicate that good follow-up after surgery, can lead to improving the level vitamin D serum.
