• This condition causes a reaction to alcohol, like a hangover but occurs almost immediately when using alcohol.

Alcohol intolerance is not an allergy, but an allergy to an ingredient in alcohol can cause similar symptoms. Alcohol allergies are an immune system response, where the immune system overreacts to an ingredient in alcohol. Allergies to grains, such as wheat, rye, or corn, or preservatives such as sulfites, can cause reactions. Allergies can be identified through a blood test, but this will not confirm alcohol intolerance. There are various home-to-laboratory test kits that can help identify sensitivities to common ingredients found in alcoholic beverages.

Prevention and Lifestyle Management

Some health conditions can also cause alcohol intolerance, while others can cause increased alcohol sensitivity. Hangovers are delayed reactions with symptoms like headache and fatigue, not directly caused by an inability to metabolize alcohol’s toxic byproducts.

Although everyone with celiac disease is sensitive to gluten, some people only experience skin symptoms without the common digestive symptoms (10, 11). Some brands advertise alcohol intolerance tests that measure IgG reactions rather than analyzing a person’s genetics.
