Does the liver eliminate alcohol from bloodstream?

Yes, the liver eliminates alcohol from the bloodstream through a process called liver metabolism. When you drink alcohol, it is absorbed into the bloodstream through the stomach and small intestine. The blood carries the alcohol to the liver, where it is broken down into harmless substances.

The liver uses a variety of enzymes to break down alcohol. The main enzyme involved is called alcohol dehydrogenase (ADH), which converts alcohol into acetaldehyde. Acetaldehyde is then converted into acetate by another enzyme called aldehyde dehydrogenase (ALDH). Acetate can be further broken down into carbon dioxide and water, which are eliminated from the body through the lungs and kidneys.

The rate at which alcohol is broken down by the liver varies from person to person. Some people may have a higher level of ADH and ALDH activity than others, which means they can break down alcohol more quickly. Others may have a lower level of these enzymes, which means they may be more sensitive to the effects of alcohol.

Factors that can affect the rate of alcohol breakdown include:

* Age: The liver's ability to break down alcohol decreases with age.

* Sex: Women tend to break down alcohol more slowly than men.

* Weight: People who are overweight or obese may break down alcohol more slowly than people who are of a healthy weight.

* Race: Certain ethnic groups, such as Asians, may have a lower level of ADH and ALDH activity than other groups.

* Medical conditions: Certain medical conditions, such as liver disease, can slow down the rate of alcohol breakdown.

* Medications: Some medications can interact with alcohol and slow down its breakdown.

If you are concerned about how alcohol may affect you, talk to your doctor.
