When ALDH2 is insufficient, acetaldehyde builds up in the bloodstream, causing symptoms such as flushing, headaches, nausea, vomiting, and, in some cases, hives or anaphylaxis. While a blood allergy test can help identify an allergy to certain components in alcoholic beverages, it won’t confirm alcohol intolerance. It’s important to consult with a healthcare provider, who can provide appropriate testing and treatment options based on a detailed medical history and observation of symptoms. Alcohol intolerance refers to the body’s inability to process and metabolize alcohol efficiently. Unlike alcohol allergy, which involves an immune response, alcohol intolerance primarily stems from enzymatic deficiencies or sensitivities to specific components in alcoholic beverages. To diagnose or test for alcohol intolerance, healthcare providers conduct an ethanol patch test or evaluate symptoms and reactions that occur after alcohol consumption.
Risk factors
In contrast, an alcohol allergy tends to be more serious, and if left untreated, can be life-threatening. Symptoms include a rash, itchy skin, swelling and crippling stomach cramps. In addition to carrying an epinephrine autoinjector, persons with an alcohol allergy should wear a medical-identification bracelet highlighting their condition. It is estimated that as many as 50 million Americans may suffer from some type of allergy.

Causes of Sudden Alcohol Intolerance
Additionally, certain medical conditions, such as liver disease or gastrointestinal disorders, will make individuals more susceptible to alcohol intolerance. For those who do not wish to abstain, limiting intake and choosing alcoholic beverages that are lower in congeners and chemicals that might trigger reactions could help manage the condition. Individuals with this condition lack sufficient levels of the enzyme aldehyde dehydrogenase 2 (ALDH2), which is necessary for breaking down ethanol in alcohol. If you’re not sure if you have alcohol intolerance or an alcohol allergy, talk to your doctor.

- The best way to prevent an adverse reaction is to avoid any item containing alcohol.
- Alcohol intolerance can happen the first time you drink alcohol, or it may come on suddenly later in life.
- The most common cause is starting a new medication that inhibits the enzymes needed to metabolize alcohol, leading to new intolerance symptoms.
- Whether you or a loved one is struggling with addiction, our expert team is here to guide you every step of the way.
- It’s crucial to carefully read labels and be aware of hidden sources of alcohol to ensure complete avoidance.
Diet and Lifestyle Changes
Alcohol intolerance occurs when your body doesn’t have the proper enzymes to break down (metabolize) the toxins in alcohol. You may be more likely to have reactions to alcohol if you have any of these factors. If you ever have trouble breathing or an itchy rash with alcohol, you likely have an allergy. If you sometimes get symptoms with certain drinks but not with others, then you are more likely to have an allergy. For those seeking addiction or mental health treatment, alcohol intolerance symptoms The Recovery Village Indianapolis Drug and Alcohol Rehab stands as a beacon of hope. It is important to note that there are no specific diagnostic tests for alcohol intolerance.
Other Underlying Health Conditions
- Taking the first step can feel overwhelming, but it’s also the start of a healthier, more fulfilling future.
- Two key factors to consider are Asian descent risk and age-related sensitivity.
- As individuals age, their ability to metabolize alcohol decreases due to reduced enzyme activity 4.
- Alcohol intolerance occurs when your body cannot effectively break down or process certain compounds in alcoholic beverages.
Your healthcare provider will ask you about the symptoms and reactions that occur after you drink alcohol. In people with alcohol intolerance, a genetic mutation (change) makes ALDH2 less active or inactive. Acetaldehyde starts to build up in your blood and tissues, causing symptoms.
