Alcohol intolerance and alcohol allergy are two different things, but they share some serious side effects. Alcohol intolerance is a condition where the body lacks the enzymes to break down the toxins in alcohol. It is a genetic condition that is more common in people of East Asian descent. Alcohol allergy, on the other hand, is when the immune system overreacts to alcohol, treating it as a harmful substance. Alcohol allergies are rare, but they can be dangerous and even life-threatening. If you experience symptoms like difficulty breathing, hives, swelling, or a rapid drop in blood pressure, seek emergency medical attention. To determine whether you have an alcohol allergy or intolerance, it is important to consult a healthcare professional, who can recommend allergy tests, conduct a physical examination, and take a detailed medical history.

What You'll Learn
Alcohol intolerance vs. allergy
Alcohol intolerance and alcohol allergy are two different conditions that share some similar symptoms. Alcohol intolerance is a genetic condition that makes it difficult for the body to process alcohol. It occurs when the body does not have the proper enzymes to break down (metabolise) the toxins in alcohol. This results in symptoms such as a headache, runny nose, upset stomach, skin flushing, and nausea. It is important to note that there is no cure for alcohol intolerance, and the long-term effects of ignoring the symptoms can be severe. The best way to manage this condition is to limit or avoid alcohol consumption.
On the other hand, an alcohol allergy occurs when the immune system mistakenly identifies alcohol or an ingredient in an alcoholic beverage as a threat and launches an attack. This can lead to an allergic reaction, which may include symptoms such as difficulty breathing, coughing, a runny nose, or stomach upset. Alcohol allergies are uncommon, but they pose a serious threat to health. Even small amounts of alcohol can trigger symptoms in individuals with an alcohol allergy.
To diagnose alcohol intolerance, self-observed symptom tracking, medical history, and a physical examination are typically used. For alcohol allergy, a doctor may conduct a physical examination, take a medical and family history, and ask about symptom severity. They may also recommend skin and blood testing. Additionally, an elimination diet may be suggested, where alcoholic beverages are cut out and then reintroduced one by one to identify specific allergens.
It is important to note that both alcohol intolerance and allergy can have serious health consequences. If you are experiencing any negative symptoms after consuming alcohol, it is advisable to consult a healthcare professional. They can help determine whether you have an intolerance or an allergy and provide guidance on managing your condition.
To check if you are allergic to alcohol, it is important to pay attention to any symptoms you experience after consuming alcoholic beverages. These symptoms can vary from mild, such as a stuffy nose or skin flushing, to severe, such as anaphylaxis, a life-threatening allergic reaction. If you experience any severe symptoms, seek immediate medical attention.

Symptoms of alcohol intolerance
Alcohol intolerance occurs when the body cannot break down the toxins in alcohol due to a lack of specific enzymes. This condition is caused by inherited genetic traits most commonly found in people of Asian descent. However, alcohol intolerance can affect individuals of all races and ethnicities.
The symptoms of alcohol intolerance include:
- Skin flushing, such as a red face
- Rapid heart rate
- Headache
- Low blood pressure
- Hives
- Runny nose
- Stomach pain or upset
- Congestion
- Nausea
- Migraines
- Histamine response, such as congestion
These symptoms can occur almost immediately, sometimes within minutes of drinking. They usually resolve when alcohol is metabolized or removed from the system. It is important to note that there is no cure for alcohol intolerance, and overlooking the symptoms may lead to severe health consequences.
While alcohol intolerance and alcohol allergy share some symptoms, they are distinct conditions. Alcohol allergy is an immune system response to the ingredients in alcoholic beverages, such as chemicals, grains, or preservatives. Allergic reactions can be severe and even life-threatening (anaphylaxis), requiring immediate medical attention.

Allergy diagnosis and testing
Alcohol intolerance is distinct from an alcohol allergy, although they share some serious side effects. An allergy occurs when your immune system overreacts to alcohol, seeing it as a harmful substance. When this happens, your body produces antibodies that trigger an allergic reaction. This can cause symptoms such as difficulty breathing, hives, swelling, or even anaphylaxis in extreme cases. On the other hand, alcohol intolerance is caused by a deficiency in an enzyme called aldehyde dehydrogenase (ALDH2), which breaks down alcohol in your body.
If you experience an allergic reaction after consuming alcohol, it is important to consult a healthcare professional. They can provide tailored advice and help determine if you have an allergy or intolerance. A doctor may conduct a physical examination, take a thorough medical and family history, and ask about your symptoms and their severity. They may also recommend skin testing and blood testing to identify specific allergens.
- Skin testing: This involves pricking your skin with a tiny amount of the substance you may be allergic to. If you are allergic, a raised bump will appear at the test spot.
- Blood testing: A blood allergy test, also called a specific IgE test, can pinpoint the allergen causing your symptoms. It measures the concentration of IgE antibodies in the blood, indicating sensitization to a specific allergen.
- Elimination diet: Your doctor may recommend temporarily avoiding all alcoholic beverages and then slowly reintroducing them one by one to identify specific triggers.
- Allergy symptom questionnaire: This helps you organize your symptom notes and guide your conversation with your healthcare provider.
It is important to note that while an alcohol sensitivity or intolerance can be uncomfortable, an alcohol allergy can be dangerous. Always consult with a doctor if you experience severe symptoms, such as throat swelling, difficulty breathing, or a rapid drop in blood pressure, as these could be signs of a life-threatening reaction.

Allergic reactions and treatment
Alcohol intolerance is caused by a deficiency in the enzyme aldehyde dehydrogenase (ALDH2), which is responsible for breaking down alcohol in the body. This can lead to symptoms such as headaches, flushing, nausea, and upset stomach. While alcohol intolerance is not a true allergy, some people may be allergic to other ingredients in alcoholic beverages, such as grains, preservatives, or additives.
An alcohol allergy occurs when the immune system overreacts to alcohol or its ingredients, treating it as a harmful substance. This can cause the body to produce antibodies, leading to an allergic reaction. Alcohol allergies are rare, but they can be dangerous and even life-threatening. Symptoms of an alcohol allergy include hives, swelling, difficulty breathing, throat swelling, a rapid drop in blood pressure, nausea, vomiting, and anaphylaxis.
If you experience any of the above symptoms after consuming alcohol, it is important to seek medical advice. A doctor can help determine if you have an alcohol allergy or intolerance through a physical examination, medical history, symptom evaluation, and allergy testing. Allergy tests may include skin prick tests or blood tests to identify specific allergens.
Currently, there is no cure for alcohol intolerance, and the only way to prevent symptoms is to avoid alcohol or limit consumption. For those with an alcohol allergy, avoiding alcohol and specific substances that trigger a reaction is crucial. In the case of a severe allergic reaction (anaphylaxis), emergency treatment is required, including lying down and administering a shot of adrenaline (epinephrine) if possible.
It is important to note that an allergic reaction to alcohol does not always indicate an allergy to alcohol itself but could be due to an allergy to a specific ingredient. An elimination diet may be recommended to identify specific triggers by reintroducing alcoholic beverages one by one. Consulting with a healthcare professional is essential for accurate diagnosis and tailored advice.

Alcohol intolerance causes
Alcohol intolerance is primarily caused by a deficiency in the enzyme aldehyde dehydrogenase (ALDH2). This enzyme is responsible for breaking down the toxins in alcohol. However, for people with alcohol intolerance, the enzyme is less active, leading to a buildup of acetaldehyde in the blood and tissues, resulting in uncomfortable symptoms.
Alcohol intolerance is often a genetic condition, with inherited traits most commonly found in individuals of Asian ancestry. Between 30-50% of people of East Asian descent experience alcohol intolerance, commonly referred to as "Asian flush" or "Asian glow". However, it is important to note that alcohol intolerance can affect people of all races and ethnicities.
Other ingredients found in alcoholic beverages, particularly beer and wine, can also trigger intolerance reactions. These include grains such as corn, wheat, or rye, as well as preservatives like sulfites. Combining alcohol with certain medications can further exacerbate these reactions.
The symptoms of alcohol intolerance typically appear shortly after alcohol consumption and can vary in severity. Common symptoms include a stuffy nose, skin flushing, headaches, an upset stomach, and diarrhoea. It is important to note that there is currently no cure for alcohol intolerance, and the best treatment option is to limit or avoid alcohol consumption completely.
While alcohol intolerance and alcohol allergy share some symptoms, they are distinct conditions. Alcohol allergy occurs when the immune system overreacts to alcohol in the body, whereas alcohol intolerance is primarily a genetic condition that hinders the body's ability to process alcohol. If you suspect an allergy to a specific ingredient in alcohol, an allergy test, such as a blood test or skin testing, may be recommended for diagnosis.
