I had my 6 month check-up and was surprised to learn that my A1C (5.9) has not changed at all since before surgery so I am still pre-diabetic. I have lost 54 pounds so this really surprised and disappointed me. Anyone have insight why this might occur? Thanks.

Maybe not enough weight is off yet. Or like my mother they could have thought it was type 2 and it turns out it is type 1 and not too much weight related. Congrats on the 54 pds I hope you solve this issue!

Get them to check your serum insulin level. An A1C doesn't tell everything.

A1c takes a while to change. The error of those tests can be as much as + or - 0.5! There are other things that can make it falsely high, like low iron. Was you iron panel normal?

Iron serum was 35 (normal is 35-155) . Is serum glucose the same as serum insulin? My serum glucose was normal- 82.

A serum glucose (blood sugar) test is not the same as a serum insulin test. Serum insulin is a better measure to determine if someone is developing full blown diabetes. People can actually have a fairly normal A1C and a very high serum insulin level, in which case oral diabetic meds won't help; those people would need insulin injections to control their glucose levels. Your iron level is on the lower end of normal, but it's still normal. Take your supplememts and if your new sleeve can handle red meats, try to include more in your intake.

My understanding is the re-routing of the intestinal track with gastric bypass gives you the best scenario for pre or diabetes reversal. In fact, the duodenum switch is done for just that reason in patients with severe diabetes (metabolic syndrome) but without a weight loss requirement. With the sleeve, you are dependent on weight loss alone. Of course, weight loss plays a huge role on diabetes but for reasons not yet understood by the medical community the duodenum when bypassed in RNY seems to offer a better result. There is a good chance the situation will improve for you but there are no guaranties not even for RNY patients. Also, don't forget that a healthier weight will have an affect on the progression of diabetes. You may never get to the full blown phase or it will slow it down. Either way you are way better off. i too have lost 50 lbs as you know with the weight gone we feel so much better. That alone is reason for celebration.
