The Nutritional Advantages of Adjustable Band Bariatric Surgery One of the issues that bariatric surgical patients deal with after a malabsorptive-type procedure like a gastric bypass operation are the micronutrient deficiencies that need to be followed very carefully. Those could be vitamin D and calcium and B12 and iron and folate deficiencies that cause various medical problems. These medical problems can be serious and patients need to follow-up with their physicians on a regular basis to make sure that they don’t develop those medical problems. The banding procedures have an advantage over these kinds of malabsorptive operations and that there is no malabsorption associated with the banding procedure. In any other case, we do ask our patients to take multivitamins on a regular basis and we do measure those same micronutrient levels on a yearly basis in the office. However, it’s very rare for a banding patient to develop serious iron deficiency or B12 deficiency or deficiencies in calcium and vitamin D due to malabsorptive issues. That’s one of the major advantages to a purely restrictive operation like the adjustable gastric banding operations.
