Continuing to drink alcohol while knowing you are intolerant (or allergic) can also have severe health consequences. If a person develops a mild intolerance to alcohol or an ingredient in beverages, they may be able to manage it themselves simply by avoiding or limiting alcohol or certain drinks. Alcohol intolerance may cause a person to experience immediate reactions after they drink alcohol, or they may develop it hours after, the day after, or even later in life. A person may experience sickness after drinking alcohol due to an intolerance or sensitivity to an ingredient.
- If you have an allergy, your immune system over-reacts to contact with a trigger or “allergen.” If you have an alcohol allergy, your immune system treats alcohol as a threat.
- Also, if your symptoms seem to be linked to an allergy or a medication you’re taking, see your doctor.
- Even drinking a small amount of alcohol (ethanol) causes unpleasant symptoms.

The immune system overreacts to this exposure in the body, treating alcohol as a threat. The body produces antibodies, and when they encounter alcohol, they set off a systemic allergic reaction. An alcohol allergy occurs when the immune system overreacts to alcohol entering the body.
Can You Develop a Sudden Intolerance to Alcohol?
Symptoms such as facial flushing, hives, nasal congestion, and nausea after alcohol consumption may indicate underlying health issues contributing to alcohol intolerance. Seeking medical advice is crucial for accurate diagnosis and management. The primary cause of alcohol intolerance is a genetic condition that affects the body’s ability to metabolize alcohol efficiently. One of the key enzymes involved in alcohol metabolism is aldehyde dehydrogenase 2 (ALDH2). In severe reactions or if symptoms persist, seeking medical attention is crucial.
Signs and symptoms
If you have a true alcohol allergy, the only way to avoid symptoms is to avoid alcohol entirely. Read the ingredient lists of foods and drinks, ask restaurant staff for information about menu items, and avoid products that contain alcohol. If you have an alcohol allergy, your immune system over-reacts to alcohol. If you have alcohol intolerance, your digestive system doesn’t process alcohol properly.
ADH enzyme variants are genetic changes that alter aldehyde dehydrogenase. 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.
Moderating Your Drinking
Symptoms include a rash, itchy skin, swelling and crippling stomach cramps. In rare instances, an unpleasant reaction to alcohol can be a sign of a serious underlying health problem that requires diagnosis and treatment. If you drink a beverage that causes a mild reaction, over-the-counter antihistamines might help relieve symptoms. However, for a severe skin reaction, weak pulse, vomiting or trouble breathing, seek emergency help right away, as you could be having an anaphylactic reaction. It won’t go away, but by taking some precautions, you can avoid the symptoms and enjoy a healthy, active life.
Let’s talk about your recovery
Avoiding alcohol is always the best option for those with alcohol intolerance, as the increased acetaldehyde levels increase your cancer risk. Avoiding alcohol also helps you to avoid the unpleasant symptoms that alcohol https://ecosoberhouse.com/article/recommended-vitamins-for-recovering-alcoholics/ intolerance can create. Alcohol intolerance caused by genetics is diagnosed through genetic testing. More commonly, however, it is diagnosed solely based on the occurring symptoms and their connections to alcohol.
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. In some causes of alcohol intolerance cases, they might use an oral challenge test to diagnose an allergy or intolerance. In this procedure, they will ask you to consume a sample of your suspected trigger.
