Those with genetic mutations affecting enzyme activity are more prone to adverse reactions, especially in environments rich in potential triggers. Alcohol intolerance mainly stems from genetic factors that affect how the body processes alcohol. The most common cause is a deficiency or reduced activity of the enzyme aldehyde dehydrogenase 2 (ALDH2). This enzyme is crucial for breaking down acetaldehyde, a toxic substance generated when the body metabolizes alcohol. Furthermore, alcohol intolerance can aggravate pre-existing respiratory conditions. For example, people with asthma may notice worsening symptoms after drinking alcohol.
- Over time, drinking shifts from enjoyment to coping with withdrawal, marking the start of alcohol dependence.
- For some, alcohol intolerance is simply a sign that their body doesn’t process alcohol well.
- People with alcohol intolerance could still consume alcohol, although they will likely experience side effects.
- It’s important to note that managing alcoholic intolerance may require a combination of approaches tailored to each individual’s specific needs.
- Histamine is a chemical signal that opens up your blood vessels, constricts your airways and gastrointestinal (GI) tract, and creates mucus.
- The risk is elevated due to the accumulation of acetaldehyde, a known carcinogen.
Alcohol Allergy vs. Alcohol Intolerance
Treatment for food intolerances usually involves avoiding foods or beverages that cause your symptoms. To test what you can safely eat, you stop eating any possible triggers for a few weeks. If you haven’t had symptoms in that time, you start adding them back in one by one. If you start having a reaction to certain foods or combinations of foods but not others, you can avoid only the ones that make you react.

Chronic fatigue syndrome (CFS) is a chronic condition involving pain, insomnia, and severe fatigue that does not improve with rest. A 2023 study found that individuals with CFS are more likely to experience alcohol intolerance. Alcohol intolerance is an immediate unpleasant reaction to consuming alcohol. It typically occurs because of a genetic difference that makes the body unable to break down alcohol efficiently. If you’re allergic to another ingredient contained in certain alcoholic products, switching to a different drink might be an option.
Medications: Use antihistamines or other drugs to manage mild symptoms
Additionally, individuals with existing allergic conditions, such as hay fever or food allergies, may experience cross-reactivity with alcohol, leading to an allergic reaction. If alcohol is causing more harm than good in your life, seeking professional treatment can be the best solution. Many people with alcohol intolerance develop a pattern of excessive drinking despite their body’s negative reactions. This can lead to dependency, increasing the risk of serious health complications.
The primary treatment for alcohol intolerance is avoidance of alcohol, as there is Alcohol Intolerance currently no cure. This is especially important for those experiencing severe reactions, as continued consumption can worsen symptoms and increase health risks. Alcohol intolerance presents unique challenges in diagnosis due to symptom overlap with conditions like alcohol allergy and histamine intolerance.
- Additionally, certain medical conditions, such as liver disease or gastrointestinal disorders, will make individuals more susceptible to alcohol intolerance.
- Understanding that process makes it easier to judge your own risk and decide whether alcohol still has any place in your life.
- If exposure occurs, OTC antihistamines can help alleviate symptoms.
- It’s important to differentiate between these two conditions because they require different treatments and management strategies.
- It’s advisable to keep a food diary to identify any specific triggers or patterns related to your symptoms.
Consistent Genetic Polymorphism
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. As a result, liver tissue can become inflamed, leading to fibrosis, and ultimately cirrhosis and liver failure. There is also an increased risk of liver cancer if you continue to drink while intolerant. Alcohol intolerance is different to having a ‘low tolerance’ to alcohol.
If you’re taking medication, check with your doctor to see if it’s OK to drink alcohol while you take it. In a few cases, alcohol intolerance can be a sign of a more serious problem. If you think you have it, talk with your doctor and find out what’s causing it. Alcohol intolerance happens when the body cannot properly break down alcohol. Alcohol allergy happens when the immune system mistakenly identifies alcohol as a threat and launches an attack that can affect the entire body. Ask your doctor for more information about your diagnosis and treatment options.

A well known pattern appears in people whose face turns red after just a few mouthfuls of alcohol. This reaction often traces back to a change in the ALDH2 gene that limits how well the enzyme removes acetaldehyde. Many people of East Asian heritage carry this change, though it shows up in other groups as well. These include foods that involve an aging or fermentation process like wine, beer and cheeses.
It’s also found in many foods and beverages, especially fermented products. For example, aged cheese, smoked meats, sauerkraut, wine, and beer tend to be high in histamines. Read beverage labels for the ingredients or additives you know cause a reaction, such as sulfites or certain grains. For many people who struggle to metabolize alcohol, the safest level is none. That is especially true if you have an ALDH2 variant, chronic liver disease, a history of certain cancers, or medicines that carry strong warnings against mixing with alcohol.
