Vitamins After Weight Loss Surgery

Why Vitamins?
After a weight loss operation, you will be eating smaller portions. Your body still needs its full daily requirement of vitamins and minerals, however. Plus, because certain nutrients (like calcium or iron) may not be well-absorbed after gastric bypass or duodenal switch, it is necessary to take additional supplements.

Each operation requires different supplements. And, each and every patient's nutritional requirements are different. Your surgeon and nutritionist will work closely with you to create a regimen that address your specific needs. These needs are not constant and may change over time.

The following guides are given as a rough overview of vitamin supplementation after weight loss surgery. These tables are for informational purposes only and are not intended to replace a personalized supplement plan from your nutritionist and surgeon!

Remember, weight loss surgery is a tool! Vitamins are only 1 aspect of how you need to care for yourself after surgery. It is also critically important to make sure that you are eating a healthy diet after weight loss surgery. To make sure that you are getting enough protein, vitamins, and minerals, you will need to meet with one of our team's nutritionists before and after surgery!
