I am a 65 year old male in good health. I don't smoke, don't take drugs (I even minimize prescriptions), am not overweight and don't eat "fast foods". Each day, though, I have a couple of drinks before dinner (1.2-1.4 oz. alcohol content). On 8/22/14, I went in for an annual physical and found there were two flags on my CBC: MCV 100.9 & RBC 4.65. My doctor tested for vitamin B12 and the level came back 1090. TSH was 2.08. Folate was not tested, but was 18.13 on 11/17/2010. My doctor has told me that either alcohol consumption or myelodysplasia can cause macrocytosis. She wants me to cut down to 2 drinks a week for a month to eliminate alcohol as a factor, then check on myelodysplasia. I don't mind doing this, but everything I have read indicates moderate alcohol use is not a factor. Since myelodysplasia seems more serious, wouldn't it be better to stop wasting time on alcohol and concentrate on other, possibly more serious, conditions?
Thanks for your help.
