Can Change In Diet Cause B12 Deficiency?

Hi

I have just come across this site. Is it free?!! I have had a biopsy of a red rash across my abdomen and arms and I have been told that I have morphea. I have ITP (variable platelet count of between 20 and 80 so no need for regular treatment) and had a B12 deficiency when I was vegan a few years ago but I am now vegetarian again and haven't had my B12 checked for years. Could any of these things be connected? I would be grateful for any advice. thanks O.V.

Hi,
Thanks for asking.
Based on your query, my opinion is as follows.
1. Vegetarians commonly have Vit B12 deficiency, but not necessary always. Vit B12 in vegetarians is usually produced in gut by bacteria.
2. Also, green leafy vegetables are rich in Vit B12.
3. No, all of them are not connected. ITP is secondary to viral infection and affects usually only platelets. It does not affect Vit B12, neither does morphea.
4. Additionally, during deficiency, you can take Vit B12 supplements or injections, which will rapidly improve it. Pernicious anemia will require evaluation, if vit B12 does not get corrected after taking oral Vit B12 for a long time.
Hope it helps.
Any further queries, happy to help again.
