What are the postoperative vitamin requirements?
Postoperatively, patients will be required to take an assortment of vitamins in order to compensate for the malabsorption experienced from the gastric bypass. A daily multivitamin fortified with iron, daily calcium supplementation, as well as weekly vitamin B12 supplementation will be necessary. Depending on your preoperative vitamin stores, additional supplementation with zinc and/or vitamin D may also be necessary.
