Is GP aware that there are auto-immune diseases including PA in your family?

Article about PA family link


Some of your symptoms can be found on lists of B12 deficiency symptoms. See links below.

Are you in UK?

If you're in UK, I'd suggest reading the complete "BSH Cobalamin and Folate Guidelines".

It's a UK B12 document that came out in 2014 and gives guidance to doctors on diagnosis and treatment of B12 deficiency and PA. click on box that says "Diagnosis of B12 and Folate Deficiency" should be on page 3 of listed guidelines.

Link below to flowchart in BSH Cobalamin and Folate Guidelines

The flowchart makes it clear that a patient who is symptomatic for B12 deficiency should have an IFA (Intrinsic Factor Antibody) test and start initial B12 treatment before results of IFA test are known.
