How Is Alcohol Metabolized in the Body?

Alcohol metabolism in the body primarily occurs in the liver. Upon consumption, alcohol quickly enters the bloodstream and travels to the liver for metabolic processes.

The main enzyme responsible for alcohol metabolism is alcohol dehydrogenase (ADH). This enzyme breaks down alcohol into a toxic substance called acetaldehyde, which can cause various negative effects. Acetaldehyde is then further metabolized into acetate by acetaldehyde dehydrogenase (ALDH). Finally, acetate is broken down into carbon dioxide and water, which are subsequently eliminated from the body.

The rate at which alcohol is metabolized varies depending on several factors, including age, sex, body weight, and overall health. On average, the liver can process approximately one standard drink (containing 14 grams of pure alcohol) per hour. Consuming alcohol in excess of this rate can lead to an accumulation of acetaldehyde and its associated adverse effects, such as headaches, nausea, and impaired judgment.

It is crucial to be aware that other substances, like Phentermine medication, can impact alcohol metabolism. Combining Phentermine with alcohol may elevate the risk of side effects and might not be advised.
