Which supplements are important after bariatric surgery (i.e., weight loss or stomach-reducing surgery)? Are there any I should avoid?
Weight loss surgeries such as gastric bypass, gastric sleeve, and gastric band procedures, reduce the amount of food and liquid a person comfortably digest in one sitting, leading to smaller meals and potentially, inadequate nutrient intake. Gastric bypass (re-routing around the stomach) and gastric sleeve surgery (removing a portion of the stomach) also reduce stomach acid and normal digestive action, leading to reduced absorption of various vitamins and minerals. The use of supplemental vitamins and minerals is recommended for gastric bypass and gastric sleeve patients, and sometimes for gastric band patients. However, for bypass and sleeve patients, the changes in digestion and nutrient absorption also mean that some supplements may not be tolerated or absorbed as well as others.
