Changes of Serum 25OH-vitaminD Level in Patients with Morbid Obesity after Sleeve Gastrectomy in Iranian Population

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 patients with morbid obesity after sleeve gastrectomy. methods: this retrospective study consisted of 952 patients (682 female and 270 male) who underwent sleeve gastrectomy by a surgical team in ghadir mother and child subspecialized 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 ng/ml to 24.6±1.98 ng/ml (p value=0.05) and in men from 15.65±1.2 ng/ml to 26.72±2.33 ng/ml (p value=0.02). conclusions: our findings shows that regular follow-up after sleeve gastrectomy contributed to improve vitamin d deficiency after 3 months in patients with morbid obesity undergoing sleeve gastrectomy, which indicate that good follow-up after surgery, can lead to improving the level vitamin d serum.
