The New Year party is over and so is binge drinking. Hangover episodes are only worth mentioning on Facebook and your liver, after breaking down alcohol and eliminating it from your body, is back doing its routine stuff.
While you gulped down drink after drink at the New Year party, did you think about how much time and energy the liver spends while performing the manunoth task of removing traces of toxic alcohol from your system?This dark reddish-brown organ – responsible for over 500 vital functions to get you going – is behind the elimination from the body of nearly 90 percent of ingested alcohol through metabolism. The remaining alcohol is eliminated through breath, urine, sweat and saliva.
Let’s hear straight from health experts so that you do not need to Google this.
“Approximately one-two percent of alcohol is absorbed directly through the mucosal lining of the mouth; two-four percent is broken down by our lungs via breath; two-six percent by our sweat glands; two-four percent by our kidneys and nearly 90 is broken down by our liver,” explained Dr. Sanjay Singh Negi, Director (HPB Surgery and Liver Transplant) at BLK Super Specialty Hospital.
“All the alcohol from one drink may well be absorbed within 3o minutes. However, if your stomach is relatively full, the alcohol will stay longer. The absorption process will be slower and may take up to 90 minutes,” Singh told IANS.
How much time does the liver take to break down alcohol – say from one 3o ml peg of whisky, 350 ml of beer (five percent alcohol) or one glass of red wine?
According to Dr. Sanjay Singh Negi, a healthy person’s liver can metabolise alcohol at a fairly consistent rate. “As a standard rule, a person can eliminate one average chink of 5 oz (15 nil) of alcohol per hour. However, there are several other factors that influence this rate,” Singh added.”Alcohol is generally cleared from the body at the rate of 15 ml per hour. So if a person consumes 3o ml (one small peg) of alcohol, it is cleared in around one-two hours. Beer (350 ml) will be cleared in two-three hours,” noted Dr. Sanjay Singh Negi, Director (HPB Surgery and Liver Transplant) at BLK Super Specialty Hospital.
According to Dr. Sanjay Singh Negi, Director (HPB Surgery and Liver Transplant) at BLK Super Specialty Hospital., the rate hi the rise of blood alcohol concentration (BAC) is influenced by how quickly alcohol is emptied from the stomach and the extent of metabolism during this first pass through the stomach and liver.”BAC is influenced by environmental factors (such as the rate of alcohol drinking, the presence of food in the stomach and the type of alcoholic beverage) and genetic factors,” Lahotin told IANS.The alcohol elimination rate varies widely among individuals and is influenced by factors such as chronic alcohol consumption, diet, age, smoking and time of day.
Let us briefly understand the mouth-to-elimination process.
Once taken, alcohol is absorbed very quickly by our body and through blood, it spreads very easily to all the organs. Alcohol molecules are very tiny and they dissolve very easily in water and fat which are prime components of the human body.
The entire process of drinking can be broadly categorised into three stages.
In the first stage, alcohol is absorbed from all parts of the gastrointestinal tract largely by simple diffusion into the blood. In a fasting individual, around 10-20 percent of alcohol is absorbed from the stomach (the volume of alcohol affects the absorption) and 75-80 percent is absorbed from the small intestine.
“Because of this, peak blood alcohol concentrations (BACs) are achieved in fasting people within 3o minutes to two hours, while non-fasting people exhibit peak alcohol concentrations within one hour and, in extreme cases, up to as much as four hours,” Singh explained.In the second phase, called distribution, absorbed alcohol is rapidly carried throughout the body in the blood and once its absorption is complete, equilibrium occurs in such a way that blood across the body contains approximately the same concentration of alcohol.
In the third and crucial elimination stage, the liver conies into the picture.
“The liver contains an enzyme called alcohol dehydrogenase which converts alcohol to acetaldehyde. Another enzyme – aldehyde dehydrogenase (ADH) – converts acetaldehyde to acetic acid, which is further converted into CO2 and water which are then excreted from the body,” professor Negi explained.
