NCT02569593

Brief Summary

Obese volunteers who have scheduled a gastric bypass (RYGB) in UZ Leuven will be asked to participate in a cross-over study using commercial available iron supplements. The aim of this study is to evaluate the absorption rate of different oral iron supplements in volunteers before and after RYGB (1, 3, 6 and 12 months post-RYGB).

Outcome Measures

Primary Outcomes (1)

  • The absorption rate from different oral Fe-supplements

    The rate and extent of absorption of iron wille be estimated by changes in serum iron concentration.

    One year

Study Arms (1)

RYGB-patient

OTHER

Patients with a planned RYGB at UZ Leuven will be recruited. Iron supplements, more specific Ferrodyn and Vista Ferrum will be administrated in these patients before and 1, 3, 6 and 12 months post-RYGB with at least 7 days between the administration of the different supplements.

Dietary Supplement: Iron supplements, more specific Ferrodyn and Vista Ferrum

Interventions

Ferrodyn is an Fe-chelate supplement. One tablet contains 28 mg elemental iron. Vista Ferrum is an iron(II)sulfate supplement. One tablet also contains 28 mg elemental iron. The volunteers will be asked to take the provided supplement orally with 150 mL of water.
