What influence a blood alcohol concentration?

* Gender: Women tend to have higher blood alcohol concentrations (BACs) than men after drinking the same amount of alcohol. This is because women have a lower proportion of body water than men, so the alcohol is more concentrated in their blood.

* Weight: People who weigh less tend to have higher BACs than people who weigh more. This is because alcohol is distributed throughout the body, so people who weigh more have more volume to distribute the alcohol over.

* Age: Older people tend to have higher BACs than younger people. This is because the body's ability to metabolize alcohol decreases with age.

* Food: Eating food before or while drinking alcohol can help to slow the absorption of alcohol into the bloodstream, resulting in a lower BAC.

* Medications: Certain medications, such as antibiotics, antidepressants, and pain relievers, can interact with alcohol and increase the risk of a high BAC.

* Genetics: Some people have a genetic predisposition to higher BACs. This is because they have a reduced ability to metabolize alcohol.
