Does anyone understand about B12 deficiency. Aibu about this doctor?

[Rufusbear]

Last year I was tested and diagnosed with very low B12, vitamin D, low folic etc and was feeling really rotten.
It had been picked up before but not treated. I was given loading doses and then three monthly jabs of B12 and tablets for the others.
Because I had neuro symptoms I have been put on 8 week jabs and tablets.

Saw doctor today for a well known related issue and was told I didn't have a B12 deficiency because b12 was stored in the body and as I was having injections I was not deficient of it therefore couldn't have symptoms of it.

Aibu to not agree with this and think it's like telling someone with diabetes that when they take their insulin they aren't diabetic as insulin is in their body?

Ah yes, sorry, missed that post!

I think 10000ug of oral B12 is the suggested high dose, although a pp said they were on higher to control their signs. I guess what your doctor was trying to say (though maybe not very clearly...) is that with a combination of the injections and an appropriate oral supplement (that should actually work on its own anyway) that it really is very unlikely you would be showing any clinical signs relating to low B12. For me the big question is why you are so low in it, are your other symptoms due to the underlying condition? Could there be other things you are deficient in that they haven't/can't check for? As they don't think it's pernicious anaemia then B12 isn't going to curing anything, just correcting one consequence of an underlying problem. I would definitely be pushing more investigations, especially into your bowels.
Good luck, sounds miserable for you.
