With an alcohol allergy, a person’s immune system overreacts to alcohol. Alcohol intolerance is a genetic condition where an individual’s digestive system cannot properly break down the substance. If people experience symptoms after drinking alcohol, they should speak with a doctor for further advice. If someone has a true allergy to alcohol, they should avoid the substance entirely. People with alcohol intolerance could still consume alcohol, although they will likely experience side effects.

It has the possibility to yield false positives for individuals whose answers reflect temporary or situational drinking. Additionally, the CAGE questionnaire focuses on alcohol use and does not capture nuanced drinking patterns or context, such as social or cultural norms. The system is designed to be a quick, initial screening tool but does not provide a definitive diagnosis, necessitating follow-up evaluations for a comprehensive assessment. Higher scores, such as 3 or 4, indicate a stronger likelihood of severe alcohol dependency or problematic drinking patterns.

Alcohol intolerance tests and how they work

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. But the hallmark symptom of alcohol intolerance is flushing of the skin of the chest, neck and face.

Hydrogen breath testing is primarily used for lactose intolerance but may also be used for conditions such as small intestine bacterial overgrowth (SIBO). Elevated levels suggest that your body recognizes those foods as a threat and causes intolerance. The only way to prevent alcohol intolerance symptoms is to avoid alcohol completely.

Alcohol Intolerance: Sudden Onset & Allergy-Like Tolerance Changes

Seeing an allergist can help you figure out what you’re allergic to. When you have an allergic reaction to alcohol, your immune system is overreacting to an ingredient in the drink. If you have other allergies, you are more likely to have an allergy to alcohol, according to research from Switzerland. An alcohol allergy means you’re allergic to an ingredient in the drink. For example, you may be allergic to red grapes in red wine, preservatives like sulfites, or to gluten in some beers. Antihistamines like Allegra (fexofenadine) and Zyrtec (cetirizine) can help alleviate histamine intolerance symptoms.

One such challenge is the difficulty in establishing a clear definition due to the vague and non-specific nature of the conditions 39. This, in turn, may cause physicians to overlook the condition or clinically misdiagnose it. This not only leads to delays in addressing and treating the condition but may also add to the psychological toll that histamine intolerance has on patients. Moreover, approaches like strict dietary treatments can negatively influence the quality of life of patients and result in poor adherence. This is further complicated by the fact that there is limited specialist expertise and inadequate awareness of the condition among the public. Histamine intolerance comes with a unique set of challenges across various areas, like diagnosis, comorbid condition complexity, and data scarcity, among others.

An allergy to alcohol has a very different cause from alcohol intolerance. Someone with an alcohol allergy has an allergic reaction when exposed to alcohol or to a component of alcohol. Often, it is not actually an allergy to alcohol itself but to a component of the alcohol, like grapes or hops. The symptoms are caused because the body’s immune system becomes overactive and attacks something found in the alcohol.

The only way to prevent these uncomfortable reactions alcohol intolerance is to avoid alcohol. A food allergy activates the immune system rather than the digestive system. A food allergy may cause hives and other rashes, difficulty breathing, wheezing, and, in severe cases, anaphylaxis. Food allergies can be life-threatening if untreated.2 In contrast, a food intolerance may cause significant discomfort and impact your quality of life, but it is unlikely to be life-threatening.
