Vitamin B12 Deficiency (Overview)

B12 deficiency can be due to a lack of absorption or intake from diet. Since B12 is primarily found in animal products (e.g., dairy, egg, meat, etc.) vegetarians are more at risk. A deficiency is suspected when rbcs increase in size (e.g., high MCV and/or MCH in cbc) and can cause megaloblastic anemia. Symptoms can include fatigue and neuropathy. It is best corrected with methyl B12 by injection.

As a matter of fact yes: I cannot go into the complex details, but I had two young patient's years ago, both of whom had elevated blood levels of vitamin B12. But both of them also had evidence of thiamin deficiency that would result in deficiency of energy. I concluded that vitamin B12 was collecting in the blood and not being used in metabolism.

Been suffering with lhermittes for a month (mris brain&c ok). Could a 5 year addiction to nicotine gum (15x2mg daily) cause vitamin B12 deficiency?

Been suffering with lhermittes for a month (mris brain&c ok). Could a 5 year addiction to nicotine gum (15x2mg daily) cause vitamin B12 deficiency?
