Sporty_g saidI am one of those "light weights" that suffers genetically from "ALCOHOL FLUSH" http://en.wikipedia.org/wiki/Alcohol_flush_reaction....I lack the physical capacity to metabolize alcohol in a more "normal" or "average" quantity. Plus, when I had Weight Loss Surgery, my digestive track was forever altered and I have a very difficult time handling sugars (alcohol).
The normal man can process 1 oz of alcohol per hour, it takes me 4 hours to process that same ounce of alcohol....so I get drunk faster on less alcohol and I stay drunk longer and it actually registers a BAC different from the little chart that is used by the police to calculate the number of drinks you had vs your weight and the BAC reading.......the only alcohol found in consumed drinks is supposed to be ethanol...
Those are two separate things you're talking about. "Alcohol flush" which you mention at the beginning, is a genetic thing which is a problem with the acetyldehyde dehydrogenase cycle, not the alcohol dehydrogenase cycle. When you later talk about not being able to metabolise alcohol(ethanol) and getting drunk faster, it has nothing to do with the genetic 'alcohol flush' aspect since acetyldehyde doesn't make you drunk, only ethanol does. So if you now find yourself getting more drunk faster, it must be entirely due to the surgery, not the genetic condition.
What's more, as a matter of statistics, the main populations which are studied with regards to the miscoded ALDH2 condition are of oriental decent where 50% actually have a ADH cycle which is MORE efficient; meaning they convert ethanol to acetaldehyde more quickly, losing the 'drunk' feeling faster. Unfortunately oriental groups suffer about 85-90% ALDH2 miscoding which results in a cycle which is only 25% as efficient as normal, so not only does the drunk feeling go faster, acetaldehyde is being produced much faster along with a greatly reduced ability to convert it further to carbon dioxide and water, increasing the symptoms we normally associate with a hangover. So in most documented population studies and statistics, the people suffering from 'alcohol flush' in fact don't get more drunk, but less drunk on the same amount of alcohol, because these populations which are studied are of oriental descent.
We covered this topic in detail at a Master of Wine seminar a couple of years ago and it busted the myth for a lot of attendees who were experts in their own right.
