B12 too high?

Posted by siouxzan71 @siouxzan71, May 17 1:21pm

I’ve been a laryngectomee for 24 years . I have Graves Disease, no thyroid, fibromyalgia, connective tissue disease, COPD, & osteoporosis. Now my Dr is concerned about my B12 level. It’s 2000. It’s been that since 2021. She doesn’t know what’s causing it. Any ideas will help. Thanks!

Well, you’re now in the normal range according to typical lab values. Every lab has a slightly different range but a 200-900 range is typical. My doc says he like his patients around 500-600.

I’m guessing here, but I suspect your neurologist gave you high-dose B12 injections or oral supplements to get your levels up. He now may likely suggest a lower dose oral supplement to help you maintain your level so your levels don’t drop.

I guess. I’m waiting his instruction. I apparently don’t absorb it well. Neither does my mom and brother. Genetic or autoimmune. B12 deficiency is a lot more complicated than I ever thought. It’s serious too. I’m very concerned about the damage it’s caused me.

It’s relatively easy to raise B12 levels by injection and/or oral supplements. The somewhat harder part is maintaining your now normal level of 700. I suspect your doctor will retest your B12 level in a few months to see if it stays normal or not. If it drops too low again you may need to consider daily oral B12 supplementation or periodic injections.

Many people don’t absorb B12 from foods for a variety of reasons. Low stomach acid, lack of intrinsic factor, lack of B12 in foods from vegetarian/vegan diets, certain medications that block B12 absorption (proton pump inhibitors, H2 blockers, antacids, etc.) to name a few.
