Having been diagnosed with B12 deficiency last December because of low serum B12 and neurological damage, my tiredness, etc was resolved with B12 supplementation (injections and daily sublingual). I felt much better.
After complications developed suggesting Crohns or SIBO, my gastroenterologist did further tests and Folate had dropped almost to the bottom of the range. This was resolved with Folic Acid supplementation.
Crohns and SIBO now dismissed and non specific B12 deficiency diagnosed.
I keep with the 2 monthly injections and daily oral.
Tiredness has again crept in.
Following an incident in London on 1st September, I was admitted to St Thomas's and referred by my gastroenterologist to a cardiologist.
Further tests done. My heart is in fantastic order and Vasovagal episode confirmed with unknown cause.
Now my free Iron levels are below normal.
Any ideas what the heck is going on?
Iron 11.3 micromol/litre range 10.6-28.3
TIBC 68 micromol/litre range 41-77
Transferrin Saturation 17% range 20-55 male
Ferritin 162 microgrammes/litre range 30-400
B12 levels are high normal, as too are Follate. Not tested on this occasion. I have a very healthy meat and fish rich diet, inc liver.
Although B12 serum levels were very low, I never showed signs of megaloblastic anaemia and now the numbers indicate iron deficiency anaemia but no other haematological measures show anaemia.
