The deficiency of vitamin D before surgery mean (35.18) which decreased then increased reaching (37.46) in the end of first year post surgery which was a significant P value 0.045, while the deficiency of vitamin B12 prior to surgery which was 51.90 then after surgery decreased then increased reaching 51.58 by the end of first year post surgery which was non-significant P-value 0.490 (P value < 0.05 significant).Conclusions: This study determined the presence of deficiencies of both vitamins D and B12 before and after laparoscopic sleeve gastrectomy during first year post surgery, so it is recommended for giving vitamin D prior to surgery, while vitamin B12 was not given.
