This condition is most common in those of Asian descent but can affect anyone, regardless of their ethnic background. This genetic condition will cause alcohol intolerance throughout a person’s life. Alcohol intolerance, also known as alcohol sensitivity, is often caused by a change that affects an enzyme called alcohol dehydrogenase. This enzyme is part of the body’s process for breaking down alcohol and changes a chemical called acetaldehyde to another chemical called acetate.
Mild symptoms include rash, but more dangerous symptoms include swelling in the face and throat, which can affect the ability to breathe. If you suspect you or someone you know is having a severe allergic reaction, immediately call 911. what causes alcohol intolerance True alcohol allergy is thought to be rare, while alcohol intolerance is more common. Some people may incorrectly assume they are allergic to alcohol, when in fact they are actually reacting to other components of alcoholic drinks.
What is alcohol intolerance?
If someone experiences a severe allergic reaction, they should go to the emergency room immediately. If they do not have an epinephrine injection to treat anaphylaxis right away, it could be fatal. We will also look at what causes alcohol allergies and review the differences between alcohol allergy and intolerance. Some types of sulfites might also trigger an asthmatic attack if you have asthma. Normally your body produces an enzyme called diamine oxidase (DAO) to break histamine down.
They can also lead to life-threatening reactions like anaphylaxis. With a serious illness, it’s better to abstain from alcohol to avoid further taxing the body. Doing so will also give it the best chance of fighting the illness effectively. Some people may find that their alcohol tolerance becomes higher with time. This is likely due to “practice” as they continue to use alcohol regularly.
What to expect from your doctor
People who have asthma, hay fever, or other allergies to foods may have a higher risk of developing an alcohol intolerance. Headaches caused by alcohol intolerance may remind you of headaches felt during a hangover. However, these are usually brought on immediately after you drink alcohol rather than the next day.
Symptoms of an allergic reaction to LTP usually appear within minutes and include swelling, itchiness, digestive problems, breathing difficulties and, in extreme cases, anaphylaxis. If you regularly played darts or pool at the pub prior to lockdown, a loss of learned tolerance could mean that you don’t play as well as you used to when you have a game after a few drinks. Over a decade later, research is still being conducted into alcohol intolerance. A 2010 German questionnaire surveyed 4,000 people and found that self-reported wine intolerance specifically was present in 5.2% of men and 8.9% of women. However, only around 20% of those surveyed completed and returned the questionnaire.

If you develop any signs of a severe reaction, you should receive one or more doses of epinephrine. It’s available in preloaded syringes, known as epinephrine auto-injectors (e.g., EpiPen). If your doctor prescribes an epinephrine auto-injector, you should carry it with you at all times. Then go to your nearest emergency department for follow-up care. If you develop symptoms after drinking alcohol, make an appointment with your doctor.
- Some people may be unable to drink alcohol without experiencing immediate feelings of sickness, or they may develop this over time after a prolonged period of drinking.

There, they will perform a skin prick test, during which a drop of alcohol is applied to the surface of your skin before being pricked with a fine needle and observed for a potential reaction. If any of these are positive, it would mean you have an allergy to alcohol. Dr Deborah Lee of Dr Fox Online Pharmacy stresses that, if you ever have any of the allergy symptoms after drinking alcohol, you should call 999 without delay. You need to get to the nearest A&E department as this can be a life-threatening medical emergency. In some individuals, variations in the ALDH enzyme can lead to a higher or lower tolerance to alcohol. For example, an inherited lack of an ALDH variant called ALDH2, common in people of Asian descent, often results in alcohol intolerance.
