This occurs because of a buildup of acetaldehyde, a toxic byproduct of alcohol metabolism, resulting from enzyme deficiencies in some individuals. If you feel unwell or experience unpleasant or uncomfortable symptoms after drinking alcohol, it can be easy to dismiss them as simply the normal effects that come after having a drink. So, if you experience the same discomfort, skin flushes or bloating whenever you have a glass of wine or pint of beer, there’s every chance you have an intolerance to alcohol. It also highlights the need to take care of other aspects of liver health, as the liver plays a significant role in alcohol metabolism. Understanding the impact of alcohol on overall health can further aid in making informed decisions about alcohol consumption. The root cause of alcohol intolerance lies in a genetic mutation affecting the ALDH2 enzyme.

Alcohol triggers blood vessels in our brain to expand, leading to an all-too-familiar pounding pain. Unlike allergies to alcohol, intolerance is largely a genetic issue caused by an inability to metabolize alcohol properly. An enzyme called aldehyde dehydrogenase (ALDH), which (normally) works together with another enzyme — alcohol dehydrogenase — to metabolize alcohol in the liver. The Recovery Village Atlanta offers comprehensive addiction treatment for drug and alcohol addictions and co-occurring mental health conditions.

Alcohol intolerance happens when your body doesn’t have the proper enzymes to break down the toxins in alcohol molecules. This is a caused by a genetic trait that is most often found in people of Asian ancestry. The liver processes ethanol into acetaldehyde, a toxic metabolite that can cause cellular damage if not further metabolized efficiently. Another enzyme, aldehyde dehydrogenase 2 (ALDH2), converts acetaldehyde to acetic acid (vinegar), which is nontoxic in the body.
