b12 and hashimotos

hello everyone

my b12 was tested in the summer and it came back as 113 so I had loading injections my parietal cell and intrinsic factor antibodies were negative. could it be that my thyroid is the culprit for the low b12 as I have hashimotos and I have just read that this can make your b12 low. is that right? If so are there any tests I should have to find out or any action I can take to make sure it does not happen?

Thank's for any help

Parietal and IFA tests are even less accurate in diagnosing that B12 serum so negative results don't mean that you don't have PA.

There are also a number of other things that can cause an absorption problem with B12 which (unless you genuinely don't have any B12 in your diet) are the general cause of a deficiency.

Unlikely that the hashimotos is causing the problem though there may be a correlation as the chances are that if you have one auto-immune disease then you will have 2 ... or more.

It is also possible that supplementing B12 may affect your thyroid levels so worth getting those monitored.

Thanks Gambit that's helpful looks like why my b12 was low will remain a mystery. I eat lots of meat so that shouldn't be it. Thanks for the help
