Vit B12 and Zinc low

You say your "blood tests show b12 and zinc a bit low."

It would be good if you could get the test results and the ranges <from  - to>.

Sadly the ranges are based on the "average" person and we are not all average.

It seems odd that your B12 level was low having been taking supplements - this suggests that you may have an absorption problem and that could well be something to do with your medication.

But the "crunch line" in your post is that your Mother had P.A. and this can be "inherited". If your doctor does not already know this fact he should be told and then he might well start treating your neurological symptoms in line with the BNF Guidelines as below.

Treatment of cobalamin deficiency

"Current clinical practice within the U.K is to treat cobalamin deficiency with hydroxocobalamin in the intramuscular form outlined in the British National Formulary, BNF, 

Standard initial therapy for patients without neurological involvement is 1000 µg intramuscularly (i.m.) three times a week for two weeks, then every three months. 

The BNF advises that for Pernicious anaemia and other macrocytic anaemias patients presenting with neurological symptoms should receive 1000 µg i.m. on alternative days until there is no further improvement, then 1 mg every 2 months.

However, the GWG recommends a pragmatic approach in patients with neurological symptoms by reviewing the need for continuation of alternative day therapy after three weeks of treatment"

I'm not a medically trained person but one who has had P.A. for 45 years.

I wish you well

interferon alpha can cause latent B12 deficiency to come to the forefront...this is rare...

hope this helps you out...pm and I will research for you...hugs
