Sorry for the long winded post in advance!
I was diagnosed with a vit b12 deficiency in October last year (level was 144). The only test done to check why was for Intrinsic factor which came back negative. I'm 33 years old and had suffered with awful vertigo all of my life which would leave me incapacitated for days as I was so dizzy & sick. Over the last 10 years or so I've visited the doctor complaining of awful bloating & gut pain (was fobbed off with it's probably IBS although I do not suffer with any of the other symptoms) plus I fell very ill & ended up in hospital for a week. I was exhausted & my mouth was covered in hundreds of ulcers so I couldn't eat or drink & ended up on a drip & steroids. I now find out my b12 level was 66 at this point & yet no one did anything!
Anyway, my new gp discovered the b12 issue by chance on a blood test which was done to try & find out why I cannot seem to fight off a viral rash called molluscum that I've had for over 2 years now.
My IGA level also came back as 'high' - gp didn't know why so just ignored it.
My white blood cell levels are bang on the very lowest end of normal.
My question is could a gut issue be causing the b12 deficiency? My nephew suffers with SIBO and had similar symptoms - would this explain high IGA levels?
Could having this affect my immune system as I seem to have awful trouble fighting anything off especially this rash.
The b12 injections have given me acne & patches of dry skin so you can probably appreciate I feel like cr*p at the moment!
I now have a swollen lymph node which is rock hard behind my right ear.
I've booked another doctors appointment but any advice would be appreciated as I feel that you need to tell them what is wrong & how to treat it otherwise you get no where
