Background: Chronic intravenous iron administration is often required after bariatric surgery. Oral sucrosomial iron has a particular form of absorption and may represent an alternative treatment.

Objective: To assess the effect of switching to oral sucrosomial iron in patients receiving intravenous iron supplementation after bariatric surgery.

Patients and methods: A case-control study was conducted on 40 women of childbearing age, of whom 20 were switched to oral sucrosomial iron, while 20 patients continued on intravenous iron sucrose every three months.

Results: No significant differences were seen in Hb, ferritin, and TSI levels before and after three months of treatment with sucrosomial iron.

Conclusion: Oral sucrosomial iron could be an alternative in patients who require parenteral treatment with iron after bariatric surgery.
