B12 and B1 High?

i just had my one year post-op tests and B12 and B1 were high (values below). Do I need to adjust? What can happen if they are too high?

• B12: 1428 pg/ml (normal = 211-911 pg/ml)
• B1: 192 nmol/l (normal = 70-180 nmol/l)

B12 and B1 toxicity can both cause problems, so I would definitely adjust my intake if I had those numbers.

If I were taking an extra B complex or B1, I'd cut back a little. But most of us don't consider that B12 too high. Not for our community. It can tank pretty quickly, and you really don't want that.

I wouldn't want my B12 below 1,000. I certainly don't want it anywhere near that 200 range. Not a chance.

WHAT GRIM SAID: Your b12 is where I aim to keep mine. I never want to go below 1000 and aim for between 1200 and 1500 -- this is the norm for most progressive bariatric centers.

The b1 is high -- I also would cut back on my B-complex, if I were taking one.

You need to adjust. If you are using patches, start using pills instead. Don't take B12 until your levels go back to normal. Did your doctor not discuss this with you.

I have had my B12 tested 3 times now since April 2016 RNY. My result only shows a value of >1000.

At my six month - provider told me to take it every other day.

Year out 4/2017 result is still >1000. So now I take B12 every third day.

I had a B12 high count at my 1 year post op exam. My surgeon had me change my dosage to taking sublingual B12 3 times a week instead of daily. At my 2 year exam, my B12 levels were normal. In fact, now I'm only taking 2 sublinguals weekly. I'm surprised your doctor didn't tell you what you needed to do to cut back. Good luck. Thank God we have our annual blood work and check ups!

my B12 has always been high. My bariatric clinic didn't suggest I cut back a bit until it went over 2000. I didn't get the impression they thought having it that high was necessarily harmful, just that I probably didn't need to be taking the pills quite as often as I was, because they were clearly working pretty well...

You probably don't need to be supplementing B12 at all, as that's more of an RNY thing than a VSG need - my doc doesn't have it in his supplement regimen at all as he does primarily VSGs and DSs., but it is in there for the legacy RNY patients.

B1 usually isn't supplemented on its own unless a specific deficiency shows up - our normal diets usually are sufficient, though some who are into low carb dieting will show deficiencies and need to supplement it.

Most VSGers I know beed B12. Most of the intrinsic factor was removed with their stomach, and they don't absorb it very well.

The only thibg that matters in the end is what labs say, and adjust.
