How Long Does It Take for Alcohol to Leave Your System?

When it comes to alcohol metabolism, the liver tends to receive most of the attention. But have you ever wondered how fast your body can break down alcohol and whether there are ways to speed up this process? A hepatologist, or a doctor who specializes in liver health, explains how your body eliminates alcohol and shares insights on what affects this process.

The liver plays a crucial role in metabolizing alcohol, converting it into a toxic substance that is then excreted by the kidneys. The amount of time it takes for alcohol to leave your system depends on various factors, such as how much you've consumed, your body weight, and overall health.

For instance, if tested in hair samples, especially at the root, alcohol can be detected up to 90 days after a person has stopped drinking. In contrast, breath tests can detect alcohol for around 12 to 24 hours, while saliva tests can also identify it during this same timeframe.

Urine tests, on the other hand, are capable of detecting phosphatidylethanol (PEth), a biomarker that reflects recent alcohol intake, up to 14 days after consumption. Additionally, urine tests can detect alcohol itself in cases where an individual has been drinking excessively, with detection times ranging from 12 to 130 hours.

It's essential to remember that these times are approximate and may vary depending on individual factors. Furthermore, it's important to note that alcohol can still be present in your system even after you've stopped drinking, which is why it's crucial to drink responsibly and be mindful of the amount of alcohol you consume.
