Symptoms of alcohol intolerance can range from mild (such as face reddening), to severe (anaphylaxis). Once an intolerance has developed, the only way to eliminate symptoms is to avoid alcohol altogether. Unfortunately, nothing can prevent reactions to alcohol or ingredients in alcoholic beverages. To avoid a reaction, avoid alcohol or the particular substance that causes your reaction. Having a mild intolerance to alcohol or something else in alcoholic beverages might not require a trip to a doctor.

For individuals carrying gene variations that impair alcohol metabolism, the best way to prevent alcohol flush reaction is to avoid drinking or to limit alcohol intake. In fact, hindering alcohol flushing elevates the risk of cancer by enabling higher levels of alcohol consumption and thus higher acetaldehyde production. People may be unable to drink alcohol without feeling sick as a result of a hangover, lack of sleep or food, or alcohol intolerance. An alcohol intolerance occurs when someone’s body lacks the enzymes to suitably digest alcohol. As a result, a person may experience facial flushing and skin and digestive issues. However, alcohol allergy occurs when someone’s immune system reacts to alcohol, causing the body to attack it.

Genetics or lifestyle factors

Doctors also tend to rule out alcohol allergy before diagnosing alcohol intolerance. Genetic tests can also evaluate if there are problems with the genes that make alcohol dehydrogenase. It is important to remember that for someone with alcohol intolerance, avoiding alcohol is more than just not drinking alcoholic beverages. Alcohol in cough syrups or some kombucha could trigger alcohol intolerance. Some people may be sensitive enough that even alcohol-based hand sanitizers can trigger their alcohol intolerance. Avoiding alcohol includes being aware of any potential exposure to alcohol.

This may impair its ability to function normally but means it is still present at normal levels. Some people with ADH enzyme variants may not even notice any symptoms, while others will have the same symptoms they would have with ALDH2 deficiency. The acetaldehyde that builds up and causes alcohol intolerance is a major contributing factor in hangovers. While hangovers are often not exclusively due to high acetaldehyde levels, they play a large role. Someone who has alcohol intolerance is more likely to have a hangover, and hangovers that do occur will be more severe than they would have been otherwise. When doctors diagnose alcohol intolerance, they typically use the immediate symptoms it causes.

Is it possible to be allergic to alcohol?

An intervention from loved ones can help some people recognize and accept that they need professional help. If you’re concerned about someone who drinks too much, ask a professional experienced in alcohol treatment for advice on how to approach that person. If in any doubt, or if you are worried about symptoms, what causes alcohol intolerance seek advice from your doctor. People of other races and ethnicities, however, can also carry these variations. If trace amounts of any of the above compounds are consumed in a drink by someone with a sensitivity, they will develop symptoms. Alcohol allergies produce rashes, severe stomach cramps, and nausea.

Alcohol intolerance is an inherited metabolic disorder that will cause unpleasant sensations and digestive upset. When alcohol is consumed, those who have alcohol intolerance will experience a variety of symptoms that tax their bodies. Combining heavy alcohol use or addiction with alcohol intolerance can result in painful and potentially long-term effects on the body. If alcohol intolerance is due to a disease or medication use, successfully treating that disease or stopping the medication will often help resolve alcohol intolerance.

Alcohol Intolerance

In fact, your body might have an inability to process other constituents of alcohol, such as histamine, yeast, grains, sulfites, or preservatives. Alcohol intolerance is different to having a ‘low tolerance’ to alcohol. The latter term is generally used in social settings to describe someone who experiences the effects of drinking alcohol much quicker than others. Also, if your symptoms seem to be linked to an allergy or a medication you’re taking, see your doctor. Treatment for long COVID, including symptoms like alcohol intolerance, typically involves a multidisciplinary approach aimed at managing specific symptoms and improving overall well-being.

Symptoms include a rash, itchy skin, swelling and crippling stomach cramps. The most common cause of alcohol intolerance is inheriting a gene that affects how alcohol is broken down. This is most common in people of Asian descent but can be present in anyone.

Delayed Symptoms

Simply avoid alcohol, limit how much you drink or avoid certain types of alcoholic beverages. You may develop an allergy to some of the ingredients in alcoholic beverages that cause you to develop an alcohol intolerance. According to Sandra Parker, alcohol abuse coach and founder of Just The Tonic Coaching, alcohol intolerance is a genetic metabolic disorder where the body can’t break down alcohol properly. This can result in an uncomfortable reaction with symptoms ranging from redness and itchiness, to a blocked nose and nausea. People who experience the alcohol flush reaction and who drink alcohol are at higher risk for cancer, including esophageal and breast cancer. The reason for this increased risk is that acetaldehyde is itself carcinogenic.

  • For example, an person who typically plays darts sober would likely experience impairment in performance if intoxicated.
  • If it’s important to you to continue to drink on occasion, you can try different types of beverages to see if any work.
  • This can result in an uncomfortable reaction with symptoms ranging from redness and itchiness, to a blocked nose and nausea.
  • Alcohol intolerance caused by genetics is diagnosed through genetic testing.
