Currently, guidelines for 25(OH)D assessment and vitamin D supplementation in bariatric patients, pre- and post-surgery, are still lacking. The aim of this work is to analyse systematically the published experience on 25(OH)D status and vitamin D supplementation, pre- and post-surgery, and to propose, on this basis, recommendations for management. Preoperatively, 18 studies including 2,869 patients were evaluated. Prevalence of vitamin D insufficiency as defined by 25(OH)D\u2009&lt;\u200930 ng\/mL (75 nmol\/L) was 85%, whereas when defined by 25(OH)D\u2009&lt;\u200920 ng\/mL (50 nmol\/L) was 57%. The median preoperative 25(OH)D level was 19.75 ng\/mL. After surgery, 39 studies including 5,296 patients were analysed and among those undergoing either malabsorptive or restrictive procedures, a lower rate of vitamin D insufficiency and higher 25(OH)D levels postoperatively were observed in patients treated with high-dose oral vitamin D supplementation, defined as\u2009\u2265\u20092,000 IU\/daily (mostly D3-formulation), compared with low-doses (&lt;\u20092,000 IU\/daily). Our recommendations based on this systematic review and meta-analysis should help clinical practice in the assessment and management of vitamin D status before and after bariatric surgery. Assessment of vitamin D should be performed pre- and postoperatively in all patients undergoing bariatric surgery. Regardless of the type of procedure, high-dose supplementation is recommended in patients after bariatric surgery.<\/jats:p>","DOI":"10.1007\/s11154-023-09831-3","type":"journal-article","created":{"date-parts":[[2023,9,4]],"date-time":"2023-09-04T08:02:27Z","timestamp":1693814547000},"page":"1011-1029","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":70,"title":["Vitamin
