In addition, stapling the stomach to reduce its size or removing part of the stomach will also effect the digestion of vitamins. In prior posts, I have addressed vitamin deficiencies that can follow gastric bypass surgery: vitamin B12 deficieny , vitamin D deficiency , trace minerals deficieny , thiamine deficieny , protein deficiency , and iron deficiency.
