What Causes Elevated MCV Levels?

I just had blood tests done and found out I am slightly anemic. My MCV are slightly large too but have been ever since 2011. I saw a hematologist two years ago and he said we needed to simply keep an eye on it. I was not anemic at the time but MCV was high. I changed my diet to gluten free, dairy free and sugar free (for the most part). Could this be causing the anemia? Should I be worried?

Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.

How much your MCV exactly is? there are multiple causes of high MCV like vitamin B12, folic acid deficiency, liver and thyroid problem most commonly. But as you said you have no other problem which means you don't have any liver or thyroid problem. which can bring it down to folic acid and vitamin B12 deficiency. You can either do there levels to confirm, or you can start green leafy vegetables and salad for folic acid deficiency and protein diet for vitamin B12. Or you can take their supplements as well.

Hope I have answered your query. Let me know if I can assist you further.
