Plus, avoiding alcohol lowers your risk for cancer and other serious diseases. If you have alcohol intolerance but still find yourself drinking excessively, despite the pain and discomfort, talk to your healthcare provider. In this case, individuals may still be able to enjoy some forms of alcohol that don’t contain the specific ingredient they are reacting to. Genome-wide association studies (GWAS) have identified specific genetic variants that contribute to alcohol intolerance and alcohol use disorder (AUD). Variants in the alcohol dehydrogenase (ADH) gene, crucial in alcohol metabolism, influence how individuals react to alcohol consumption. Certain alleles in the ADH1B gene can lead to the accumulation of acetaldehyde, a toxic byproduct causing symptoms of alcohol intolerance.
What Causes Alcohol Intolerance?
Some people may even have reactions to grapes or corn used to make wine and distilled liquors. Tolerance is an important factor in understanding our drinking habits. It’s also important to remember that drinking as much as you used to after a period of drinking less (or not at all) could lead to greater intoxication, blackout and accidents. So if you plan to head back to the pub with friends now that lockdown is over, be mindful of how your drinking has changed so you can stay safe and enjoy that first tipple.
Your Guide to Alcohol Intolerance
A true allergic reaction happens when your immune system goes into overdrive to attack something it sees as a threat. Allergic reactions can cause hives, facial swelling, nausea, and vomiting. They can also lead to life-threatening reactions like anaphylaxis. People with an alcohol intolerance or sensitivity can start feeling sick after just a few sips of alcohol.

- There are genetic tests that can tell you if you have an ALDH deficiency.
- Your healthcare provider will ask you about the symptoms and reactions that occur after you drink alcohol.
- It is possible for a person’s tolerance to certain ingredients to change over time, and an intolerance may just happen suddenly due to genetics.
- However, people with alcohol intolerance often have a genetic variant that causes ALDH to work less effectively.
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. Alcohol intolerance can result from a genetic condition where the body cannot break down alcohol to digest it correctly.
This enzyme deficiency is most common in people of East Asian descent. An allergy is when your immune system has an unusual reaction to a substance, like dust or nuts. Alcohol intolerance is linked not to your immune system, but to your metabolic system. With alcohol intolerance, your body isn’t reacting to the presence of alcohol; it’s simply taking a long time to break alcohol down and flush it from the body. Alcohol intolerance means it’s difficult for your body to break down (metabolize) alcohol. This allows toxins to build up, resulting in facial flushing and other alcohol intolerance symptoms.
Alcohol intolerance occurs when the body does not have the correct enzymes to break down the toxins in alcohol. Some people may find relief with diamine oxidase (DAO) supplements, which may assist your body in breaking down histamines. Sulfites interact with stomach acid to release an irritant gas called sulfur dioxide, which can cause airway irritation in susceptible individuals. Alcohol contains metabolites, which are substances produced during metabolism. Doctors have found that a problem with ALDH2 (the enzyme that helps break down the byproduct of alcohol) is genetic. Therefore, it is likely that your family members are at risk for the same problem.

Although red wine is especially high in histamines, all alcoholic beverages have high levels of histamine. A reaction to high-histamine foods could be a sign of histamine intolerance. Your body has two enzymes that are supposed to break down histamine, but sometimes they don’t work as well as they should. By employing these strategies, individuals with alcohol intolerance can maintain an active social life while managing their condition.
How Do You Prevent Alcohol Intolerance?
For mild intolerances, you should either avoid alcohol, limit how much you drink or avoid certain types of alcohol with ingredients that may cause a reaction. However, if you have a serious allergy-like reaction following alcohol intolerance symptoms drinking alcohol, consult a medical professional. Alcohol intolerance can cause immediate, uncomfortable reactions after you drink alcohol. The most common signs and symptoms are stuffy nose and skin flushing.
- A compromised liver struggles to process alcohol efficiently, leading to adverse reactions after consumption.
- Individuals with enzyme deficiencies or underlying health conditions contributing to alcohol intolerance should consult healthcare providers for personalized treatment plans.
- As a result, acetaldehyde builds up in their body, leading to uncomfortable symptoms.
- One bad night doesn’t necessarily mean you are intolerant to alcohol.
- In fact, alcohol intolerance can develop at any stage of life, and it’s something that can happen to anyone.
