Alcohol intolerance mechanism involves the deficit of a gene code that conditions the production of Aldehyde dehydrogenase (ALDH2) enzyme. This enzyme is necessary for the digestive breakdown of alcohol into acetic acid for absorption in the body. The deficit of the gene code required to produce this enzyme is genetic and is the main cause for Asian alcohol allergy.
- The term alcohol intolerance is used for those who cannot process alcohol in the normal way.
- However, asthma experts warn sufferers to choose their drinks carefully, because even low-sulphite wines will contain some sulphites.
- If this is you, you can consider drinking potato-based or grape-based vodka.
- Why some people experience allergic reactions to alcohol – when small amounts are already produced by the body naturally – is yet unknown to researchers.
- Alcohol allergy is an immune system response — your immune system overreacts to an ingredient in alcohol.
An allergy or intolerance to alcohol is not always responsible for symptoms occurring after drinking alcohol. An allergic reaction might not occur the first time a person encounters an allergen. However, they can come on suddenly, and a person could develop an alcohol allergy health topics at any point in their life. In people with alcohol intolerance, a genetic mutation (change) makes ALDH2 less active or inactive. As a result, your body can’t convert acetaldehyde to acetic acid. Acetaldehyde starts to build up in your blood and tissues, causing symptoms.
What’s the difference between alcohol allergy and alcohol intolerance?
If you have an alcohol allergy, make sure to have epinephrine shots with you at all times and wear a medical ID bracelet that tells health professionals you have an allergy. If you’re taking medication, check with your doctor to see if it’s OK to drink alcohol while you take it. If a person is allergic to a particular ingredient found in some drinks, they could switch to drinks that do not contain it. However, some people with Hodgkin lymphoma experience pain in their lymph nodes after consuming alcohol. Hodgkin lymphoma is a blood cancer that can affect a person’s lymphatic system.
However, only around 20% of those surveyed completed and returned the questionnaire. As a result, the study’s findings may be an under-representation. It is difficult to establish a full picture of the prevalence of alcohol intolerance, though. They can range from mild to severe, according to Richmond, and may include runny nose, coughing, wheezing, itching or hives. More severe symptoms include swelling of the face, mouth, or tongue; nausea and vomiting; diarrhea; or lightheadedness.

This is caused by inherited (genetic) traits most often found in Asians. Neither Schaffner nor Rahman could explain why light drinkers have a lower risk of all-cause mortality than nondrinkers. But they agreed that alcohol is a major public health challenge, not only in the U.S. but around the world.
When we drink alcohol, an enzyme in our bodies called alcohol dehydrogenase (ADH) breaks it down into a compound called acetaldehyde. Another enzyme, aldehyde dehydrogenase (ALDH), then turns acetaldehyde into non-toxic acetic acid (vinegar). According to the Cleveland Clinic, alcohol intolerance is caused by a genetic metabolic disorder that prevents the body from producing the enzymes necessary to process alcohol. Alcohol allergy symptoms are caused by the presence of an “allergen” in the substance which provokes an immune response in the body. The immune system perceives alcohol as a treat to the body due to the presence of allergens, and this triggers the production of counter antibodies called Immunoglobulin E (IgE). The product of the interaction between antigens and allergens is an allergic reaction.
What is alcohol intolerance?
People of other races and ethnicities, however, can also carry these variations. “Alcohol and sulphites tend to evaporate away during cooking, so the potential for intolerances is certainly reduced,” Dr Watts says. However, if you’re allergic to an ingredient found in certain alcoholic drinks, dishes which contain that drink are not safe to eat.
In some cases, reactions may also result from an allergy to a grain such as corn or wheat in alcoholic beverages. If a person combines alcohol with certain medications, this may also cause a reaction. An intolerance may arise when the body is lacking an enzyme that is needed to properly digest and eliminate a food or substance (or in this case, the alcohol itself).
You might also react to certain alcoholic beverages if you have a histamine or sulfites intolerance. In very rare cases, reactions to alcohol may be a sign of Hodgkin’s lymphoma. People may be unable to drink alcohol without feeling sick as a result of a hangover, lack of sleep or food, or alcohol intolerance.
Milder reactions to alcohol may also occur
Alcohol intolerance is caused by a genetic condition in which the body can’t break down alcohol efficiently. The only way to prevent these uncomfortable reactions is to avoid alcohol. The study, which included nearly 5 million people, found that low-volume drinkers had a significantly lower mortality risk than did lifetime abstainers. To begin, alcohol intolerance is a genetic condition characterized the most common causes of bruising after drinking alcohol by the inability to process alcohol efficiently. Dr. Steven explains that there are two enzymes involved in metabolizing ethanol, an intoxicating agent that exists in different amounts across wine, beer, and spirits. Dr Fox explains that the science behind this is that dangerous levels of enzymes are accumulating in the cells of your body when you drink alcohol, and they cannot be broken down.
Changes in alcohol tolerance over time
That’s because in the UK, alcoholic drinks manufacturers don’t have to put an ingredients list or nutrition information on the label. So, Dr Sim urges anyone who knows they’re allergic to certain foods, particularly grains, to be aware they could be in drinks, too. In other cases, people can be intolerant to the chemicals that give alcoholic drinks their flavour and colour, not the alcohol itself. Histamine (found in red wine) and salicylates (found in wine, beer, rum, and sherry), are common examples. Other allergens present in alcoholic beverages in high quantity include; wheat, barley, hops, grapes, egg protein, yeast, sodium metabisulphites, rye, and gluten. The higher the presence of each of this allergen in an alcoholic beverage, the more chances there are of an intolerance reaction.
Common Food Allergens in Alcoholic Beverages
In addition to this, studies have identified a link between alcohol consumption and an increased risk of certain cancers. Research suggests that the more alcohol a person consumes, or the more frequently it is consumed, raises their likelihood of developing cancers such as breast, head and neck, oesophageal and more. If you continue to drink alcohol and suffer from alcohol intolerance, this is likely to cause liver damage. It is important to seek specialist advice if your suspect some sort of alcohol intolerance, as alcohol intolerance and alcohol allergy are commonly confused and misdiagnosed. People who experience low tolerance can continue to consume alcohol as long as they know their limits and do not exceed the recommended units per week – around 14 units per week for men and women.
