What is the relationship between vitamin deficiency and pernicious anemia?

It's the cause. Pernicious anemia is caused by vitamin B12 deficiency, which is most commonly caused by lack of intrinsic factor, which is a protein that's made in your stomach. Other causes of low B12 and other vitamin deficiencies can cause a nearly identical anemia, but then they are not called "pernicious" anemia.
Vitamin B12. Pernicious anemia is caused by lack of vitamin b12. There are a number of causes of that, but in the end, it is due to low B12 levels. The body makes large, immature red blood cells when the B12 level is low. Some people cannot absorb B12 from their stomach, so they get B12 injections, which usually solves the problem.

Positive mthfr heterozygous after multiple miscarriages, known pernicious anemia, what is the likelihood of having other b vitamin deficiencies?

Low Probability. Mthfr - methylene tetrahydrofolate reductase deficiency - has created debate among doctors. Heterozygous means you have one normal copy of the gene and one mutated. Some, but not all believe it is associated with miscarriages. B12 deficiency, pernicious anemia, is usually due to inability to absorb b12, but can happen in strict vegetarians. Likely only B12 would be low and not other b vitamins. Read more...

What is a recommended diet for someone with hypothyroidism, hypercortisolism, pernicious anemia, and a vitamin d2 deficiency?

Gluten free. Possibly gluten and dairy free. Malabsorption can be caused by gluten sensitivity damaging your gut cells. Test thyroid properly. Check free T3 and reverse t3. Ft3 should be in upper range and rt3 in lower range. If your ratio is off, you may need Armour Thyroid or t3, and synthroid (thyroxine) would be the wrong med for you. Read more...
