Hi Chirley,

Thanks for posting this. Many who have undergone weight loss surgery ended up vitamin and mineral deficiencies. B12 being one of the most missed. They ended up with multiple issues as you noted. If caught early enough, many of the problems can be reversed.

The absorption of B12 is very small when taken orally. That's why the larger doses are needed and it usually works best if taken on an empty tummy.

I'm glad they're treating your B12. For many though, one shot a month is not enough to get the levels up. Many doctors will do loading doses to get the level up and then go on a maintenance dose. There have been many studies confirming oral B12 supplementation is just as effective as injection.

Anyone with serum B12 below 500 is suspect and should be investigated.

Saw your other post...glad you're doing better.
