Macrocytosis: or large red blood cells, can be caused by excessive alcohol intake, even with normal levels of folic acid and B12. The mechanism whereby alcohol ingestion causes macrocytosis is unknown, but is though to be due to alcohol byproducts like acetaldehyde. The equivalent of 1 bottle of wine per day for 6 or more months can cause. Reverses after cessation of alcohol usually.
