Alcohol is absorbed differently.
Why does alcohol get into the bloodstream so quickly?
Alcohol is absorbed very quickly by the blood and spreads easily to all the organs. That’s because alcohol molecules are very tiny. They don’t have to be broken down by digestive enzymes to get into the blood, and they dissolve easily in water and fat, both of which are prime components of the human body.
Why is alcohol absorbed more quickly when the stomach is empty?
Alcohol moves quickly from the mouth to the stomach and on to the intestines. Some of it is absorbed directly through the mucosal lining of the mouth and oesophagus; some is absorbed through the walls of the stomach and the rest is absorbed by the intestines, mainly the small intestine.
If there is no solid food in the stomach or intestines, the alcohol will come into contact with the intestinal walls more easily and pass quickly into the blood. All the alcohol of one drink may well be absorbed within 30 minutes.
However, if your stomach is relatively full, the alcohol will stay there longer. The absorption process will be slower and may take up to 90 minutes.
Why is stronger alcohol absorbed more slowly?
Beverages that are more than 20% alcohol irritate the lining of the stomach. This slows the opening of the pyloric valve, through which the contents of the stomach pass into the small intestine. Drinking several shots of spirits one after the other in the hope of getting drunk quickly may actually produce a delayed reaction.
Why does alcohol go to your head so quickly?
Once it’s in the bloodstream, the alcohol spreads to all parts of the body and is distributed in all tissues containing water. Because alcohol is carried by the blood, it follows that it will be delivered particularly quickly to organs with many blood vessels, such as the brain, the lungs and the liver.
