Causes of alcohol allergy


Allergies caused truly by alcohol are very rare. Alcohol allergy is mostly caused by the various components used in its making.  These components are the potential allergens present in alcoholic beverages. These common allergens present in alcohol are- grapes, yeast, rye, barley and wheat.
Alcohol intolerance is more common that its allergy. When your digestive system is unable to break down the alcohol taken it, it gives rise to alcohol intolerance. Mostly people think alcohol allergy and alcohol intolerance are the same and therefore, use these terms inter changeably.

In all allergies it is the immune system that reacts with the allergen and due to this a reaction takes place. Same is the case with alcohol allergy, when alcohol enters the body, the immune system sees it as a threat to the body. To fight against it, the immune system releases anti-bodies. This causes an allergic reaction.  Alcohol allergy is a type1 or IgE mediated allergy. IgE also known as immunoglobulin E is the anti-body released by immune system to fight against alcohol.

Alcohol can also be related to histamine intolerance. Histamine can be found in various foods and drinks including alcohol drinks like wine and beer. Our body produces diamine oxidase (DAO) which is an enzyme produced by the body to break down histamine present in food and beverages. Histamine also occurs naturally in the body. Histamine intolerance takes place when your body is not able to produce enough DAO to breakdown the histamine that is present in your body. The excess histamine which is not broken down reacts with your body.

Red wine is more potential to cause histamine intolerance as it contains high levels of histamine. The symptoms of histamine intolerance are somewhat same as an allergy and include- redness of skin, irritated and itchy skin, abdominal pain, cramps, hives, diarrhoea, difficulty in breathing. People who suffer from eczema, histamine intolerance can increase their problem.

If you observe any symptoms after the consumption of alcohol it becomes necessary to get diagnosed to determine the cause and type of allergy. Proper diagnosis also helps the doctor to determine whether the symptoms arise due to alcohol allergy or alcohol intolerance. Once it is determined the doctors can easily proceed with medications. The best way to avoid any of the both conditions is to simply avoid alcohol or anything that contains alcohol.
