It’s important to understand Vitamin D metabolism and deficiency potential following weight loss surgery Vitamins after DS need to be followed via laboratory blood studies. There are basic vitamin needs but individual needs should be based on medical history, genetics, alimentary limb length, common channel length and other surgical and physiologic determinations. Vitamins after DS are a life long commitment as well as protein needs and hydration. Duodenal Switch is a malabsorptive procedure which requires at least yearly laboratory blood studies, daily vitamins/minerals, daily high protein and daily hydration intake. There is not an all in one vitamin that is adequate for a DS patient or tailored to your individual needs. (example: you may need more Vitamin D and less Vitamin A if you are taking a all-in-one vitamin you can’t get more of one and less of another vitamin)
DS patients are recommended to take Dry forms (water miscible form) of Vitamin A, D3, E, K due to the fat malabsorption after DS. Dry formulations by Biotech are processed so they can be absorbed by a water soluble method after the DS procedure. Vitamin D seems to be the vitamin that can become deficient the easiest, followed by Vitamin A. Take these vitamins away from dietary fat.
In some cases, patients may need injectable Vitamin A or D to improve vitamin levels.
Many DS surgeon’s do not recommend Children’s vitamins or chewable vitamins unless there is a specific reason or need for them.
