Your vitD is a little below range so might be worth asking GP about that.

You are being treated for an iron deficiency.

Although the title of this forum includes the word anaemia PA is actually a condition that leads to problems absorbing a particular vitamin B12, and one of the results in a particular type of anaemia - macrocytic anaemia, in which red blood cells are larger and rounder than normal - but this isn't a defining characteristic and this type of anaemia is quite different from an iron based anaemia.

However, having said that, it can be quite common for absorption problems that lead to B12 deficiency to also lead to iron deficiency but interpreting whether there is a B12deficiency from blood results in the presence of microcytic (iron based) anaemia can be very difficult - particularly as the test for B12 - serum B12 - is a rough guide at best.

B12 deficiency tends to develop over a very long period of time - also overlaps with symptoms of folate deficiency and a number of conditions. folate deficiency tends to manifest much quicker.

symptoms of B12 deficiency can be found here


suggest that you ask for copies of your blood tests - and if B12 and folate haven't been tested ask if they can be tested.
