I had an appointment with my GP yesterday as a follow up after my loading doses. (A little background, I had a B12 blood test done and was told my results were normal but when I asked for a copy these were just above the threshold for deficient so the GP agreed to give me the loading doses and see how I felt) I discussed with my doctor yesterday that I had felt some improvement although nothing drastic but definitely a noticeable improvement.
She advised that she was willing to prescribe B12 injections 3 monthly for 1 year and then review after this with blood tests. I voiced my concerns that after having the injections my B12 would be high so may not show up on a blood test straight away. She said that B12 deficiency is either caused by dietry or PA and as I was not aneminc it wouldn't be PA, I pointed out that you do not have to be anemic to have PA. I asked for the IF test to see if I had PA but she said she is not sure if the lab would do this as I was not anemic but would contact me.
So I am just wondering if because I have had the loading doses (4weeks ago was my last) if this will affect the IF test if she agrees to give me this?
She advised that as it is unlikely I have PA and each B12 injection is enough for 1 years supply that after having 4 more injections I should not be deficient but I am worried that I will slowly start to decline again.
Is there any logic in what she is saying and can anyone give me any pointers of what to do next for the next time I speak to her.
