Alcohol allergy also known as alcohol intolerance is a rare condition where a person experiences unpleasant reaction after consuming alcohol. It is a genetic disease where the body fails to break alcohol. It is caused by the absence of enzyme aldehyde dehydrogenase and mostly common in people of Asian origin.

The immune system reaction to allergen or irritation varies from one person to another. And therefore, the alcohol allergy symptoms may also differ in different people. Some people are able to end irritations beyond certain levels ie until it becomes allergen. Alcohol allergic reaction rarely occurs among people with strong physique and if it does occur, it is usually mild. Additionally, the reaction is depended on the immunity of the person

This condition is a rare occurrence in the US but it is a common occurrence in Asian countries. People with allergic reactions of any kind are at more risk of developing alcohol allergy compared to those who do not have an allergy. Alcohol intolerance can cause an instant adverse effect on an individual as it enhances the production of histamines but reduces the capacity of the body to break it down.
