<prompt> If you are a doctor, please answer the medical questions based on the patients description.I just got my blood work done and my doctor has indicated that my MCV count was high at 103. All the other results came back normal ie: iron, b12, frolic acid, liver enzymes ECG and everything else under the sun! If I stop consuming alcohol on a daily basis will it bring down my MCV count and if so how long does it take to bring it down to a normal level? Thanks in advance  <response>: Hello, you should compare this MCV 103 with older measurements. If your values were lower in the past than your implied high alcohol consumption may cause it, although this is usually attributed to malnutrition in alcoholic patients, that is reduced consumption of folic acid and B12 vitamin. Increased MCV may also be found in various hematologic conditions including the myelodysplasia syn Chat Doctor. The comparison will answer whether investigation is needed or not. If youve always had a value around 103 then no further investigation would be warranted. I hope Ive helped! If youd like more information, please let me know. Ill be glad to answer. Kind Regards!
