Changes of Serum 25OH-vitaminD Level in Obese Patients after Sleeve Gastrectomy in Iranian Population

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.

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.

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).

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.
