I am 16 days post op, i went and got a B12 shot in Aug, and then again in Sep. But my primary care doc required me to do a lab test to see what my levels are at. I was just wondering if they did it wrong, They gave me the then sent me to the lab for the test. wouldnt it of made more sense to test on another day or before giving the shot?

Today I got the lab results back and its says my B12 is 2000 and my PCP wants me to stop doing the shots. Because to him its way to high. I though i read some where that 1500-2000 are the best numbers for gastric patients.

So i guess my question is did getting the shot right before the lab work done effect the test?

Yes, that may have affect the results. In addition, you should not stop B12 altogether, though you may not need shots as often or may not need the dose you've been taking. The ASMBS says all RNY patients need to supplement B12 because we lack intrinsic factor in our pouch. Perhaps your PCP isn't aware of that.

Hi Kelly - excess levels of B-12 aren't dangerous, right? I thought we just peed out what we didn't need. Unlike D-3 that can get toxic if we overdo it... Am I right? Thanks :)

Correct.

So you're taking 80,000 IU a day? That may be too much. I think it's the vitamin D Council that says toxicity is unlikely to occur unless you take more than 100,000 IU a day, but I would be surprised if anyone needed 80,000 IU a day. What's your vitamin D level?

I won't know til my 3 month check in November so since I take my calcium 3X a day and you should be taking D3 with it I take 2 with each of my calcium ....I thought because of the malabsorbtion that would be best ....should I cut it down to one with each ...oh and it is 60 000 not 80 000 my mistake ......getting the vitamin thing down hasn't been easy

I personally wouldn't take that much unless you get labs done that show you need it. It's not necessary to take D3 with each dose of calcium. It is necessary to have a vitamin D level of at least 80 (as measured with a blood test) in order to absorb calcium properly. But you don't need to take them at the same time. Most post ops seem to need between 10,000 IU and 25,000 IU daily in order to maintain a level of at least 80. Personally, I wouldn't take more than 10,000 IU until you get labs done to see what your level is. You can, if you want, ask your doc to order a vitamin D level now so you can see where you stand instead of waiting until November.

Thanks Kelly I just assumed that that is what they wanted us to do as they wanted us to take the calcium citrate with vitamin d and I bought them separate .....I will just take it once with my first dose. I wish they has clear cut rules across the board.

Excess B12 levels will give you similar symptoms to a deficit. There may also be a link to excessive B12 supplementation and certain cancers.

It is NOT recommended that anyone have levels at 2000+. Anyone with medical training would attest to that and it is why the OP's PCP is concerned ...

If you or anyone else doesn't trust their doctors, look at the research for yourself and don't trust what anyone tells you on here ... I agree that not all doctors are au fait with nutrition and vitamins etc, but being able to google doesn't make anyone here an expert either!
