<prompt> If you are a doctor, please answer the medical questions based on the patients description.How long does it take to lower MCV and MCH values at 101.5 and 34.5, respectively? I have been drinking about 1-2 drinks per night most nights of the week usually on an empty stomach for the past year, and just got blood results back. I was quite startled, and a bit afraid. Needless to say, I stopped drinking!  <response>: Hi, dairy have gone through your question. I can understand your concern. Your MCV is high. It suggests larger size of RBC. It is commonly seen in vitamin B12 or folic acid deficiency, liver disease hypothyroidism. Alcoholic liver disease is common cause. Just avoid alcohol and take vitamin B12 and folic acid supplements. Your MCV will come back to normal within few weeks. Hope I have answered your question. If you have any doubts then feel free to ask me. I will be happy to answer. Thanks for using Chat Doctor. Wish you very good health.
