Because the condition is inherited, there is no way to cure or treat it. Your healthcare provider can recommend ways to limit unpleasant symptoms. People of East Asian descent are more likely to have the inherited genetic mutation that causes alcohol intolerance, so they develop the condition at higher rates. Anyone can have the enzyme problem that causes alcohol intolerance.
Risk factors
Alcohol intolerance happens when your body reacts in an unpleasant way to alcohol, but the process doesn’t involve your immune system. You may develop many symptoms, but you won’t have an anaphylactic reaction. In addition, older adults also experience a change in their renal function and balance of water and sodium, which raises their risk of dehydration. This suggests that if they drink alcohol, they may become dehydrated quicker and feel the effects more. If you experience any of these symptoms after consuming alcohol, seek immediate medical care.
- Do you suffer from terrible hangovers or feel unwell after drinking just a small amount of alcohol?
- You may also have other symptoms, such as nausea, vomiting, diarrhea, dizziness, heart flutters, and a stuffy or runny nose.
- Even if neither parent exhibits symptoms, they can still transmit a mutated gene that leads to this condition.
- Symptoms may occur within seconds or minutes of alcohol exposure and could trigger after exposure to even tiny amounts of the allergen.
- Yeast is used in all fermented alcoholic beverages, including beer, wine, hard cider, and sake.
Recognizing Immediate Symptoms of Alcohol Intolerance
ALDH turns aldehyde into acetic acid, a nontoxic substance that doesn’t cause any harm. Some people don’t have enough of an enzyme called aldehyde dehydrogenase (ALDH). People can develop an alcohol intolerance for a couple of reasons. Over time, a person’s tolerance may also change due to changes in metabolism, body mass, and bodily functions as they age. Alcohol intolerances are usually genetic but may also occur without a known cause.
- Although not a true allergy, in some cases, what seems to be alcohol intolerance might be your reaction to something in an alcoholic beverage — such as chemicals, grains or preservatives.
- Histamine (found in red wine) and salicylates (found in wine, beer, rum, and sherry), are common examples.
- Equally, increased alcohol consumption during lockdown could lead to increased metabolic tolerance, where a greater amount of alcohol is needed to feel intoxicated.
- Over a decade later, research is still being conducted into alcohol intolerance.
Alcohol Withdrawal Symptoms: What Does Detoxing Feel Like? A Timeline
However, people with alcohol intolerance often have a genetic variant that causes ALDH to work less effectively. As a result, acetaldehyde builds up in their body, leading to uncomfortable symptoms. This accumulation can cause facial flushing, nausea, alcohol intolerance symptoms rapid heartbeat, and headaches – the telltale signs of alcohol intolerance. Symptoms of alcohol intolerance appear within minutes of alcohol consumption. Common signs include facial flushing, nausea, rapid heartbeat, headache, and nasal congestion.
Health topics
Symptoms of an alcohol allergy include rashes, itchiness, swelling and severe stomach cramps. Allergy symptoms are often more painful and uncomfortable than alcohol intolerance symptoms. In rare cases, if untreated, an alcohol allergy can be life-threatening. In some cases, sudden onset alcohol intolerance is triggered by the presence of a new disease. People with the ALDH2 deficiency are at higher risk for certain types of cancer, including liver cancer.9 Because alcohol is a carcinogen, drinking already increases cancer risk. In particular, many people with alcohol intolerance wonder how to prevent the alcohol flush reaction, because they consider it embarrassing or unattractive.
- Alcohol intolerance can cause immediate, uncomfortable reactions after you drink alcohol.
- Furthermore, excessive alcohol use is a consistent risk factor for blood or brain vessel blockage diseases, such as coronary artery disease and cerebrovascular disease.
- These models address both the immediate symptoms of intolerance and the broader health implications of alcohol consumption.
- In other cases, people can be intolerant to the chemicals that give alcoholic drinks their flavour and colour, not the alcohol itself.
- Additionally, people may seek support from family and friends or advice from a medical professional if they require longer-term support.
- Red wine contains high levels of histamine and may cause headaches, congestion, and itching in people with histamine intolerance.
- The difference between the two has to do with how the body reacts to alcohol.

What is the Difference Between Alcohol Intolerance and Alcohol Allergy?
- Additionally, maintaining a healthy diet and staying hydrated can support overall well-being and reduce the impact of accidental alcohol exposure.
- This condition is characterized by an immediate, uncomfortable reaction to alcohol consumption, which ranges from mild to severe.
- Even so, if you have a severe corn allergy, you may want to avoid corn-based spirits, most especially bourbon.
