Some individuals think that flushing is a sign of being allergic to alcohol but it is really a manifestation of alcohol intolerance. This alcohol flush reaction is more common in those of Asian descent, due to genetic difference associated with the foods they eat, particularly rice. Facial flushing is a side effect of alcohol consumption in some individuals.
Signs and symptoms of an alcohol allergy can include abdominal cramping, respiratory distress and extreme skin rashes. Alcohol allergies can induce urticaria (hives) and may aggravate symptoms if you already have hives.
- Nose And Mouth Swelling: A person allergic to histamines may experience nasal swelling and congestion.
- Stomach cramps and nausea
- Heart rate elevates
- Alcohol might increase the reaction to food allergies
- Hives: A person allergic to sulfites may experience hives or anaphylaxis.
- Migraines: Drinking alcohol can trigger migraines in some people, possibly as a result of histamines contained in some alcoholic beverages. Your immune system also releases histamines during an allergic reaction.
More often, alcohol exacerbates underlying conditions such as asthma, urticaria and rhinitis because it opens up blood vessels. Sensitive people may get wheezy, headaches and skin flushes.
