Yes, the B12: B12 deficiency is the most common complication of gastric bypass because the stomach produces intrinsic factor which your body needs to absorb B12. Usually you can count on receiving B12 supplementation for the rest of your life following gastric bypass. Because the problem is the lack of intrinsic factor, oral B12 doesn't always work and you need shots. Not sure what the "sharp zaps" in toes are
