Alcohol Allergies and Intolerance

Allergy tests such as skin prick or blood tests may also be conducted to identify specific allergens. Yes, it is possible to develop alcohol intolerance later in life. This can occur due to changes in enzyme production, such as reduced levels of aldehyde dehydrogenase, or due to other health conditions like liver disease or medication side effects.

How is alcohol allergy diagnosed?

• If someone believes they have an alcohol allergy or intolerance, they should stop drinking alcoholic drinks and visit their healthcare provider for testing and advice.
• In people with true alcohol allergy, as little as 1 milliliter (mL) of pure alcohol can trigger an allergic reaction.
• People often call alcohol intolerance an alcohol allergy, and vice versa.

It is unclear if that number reflects the general population. Avoiding alcohol is the only sure way to prevent an alcohol-related reaction. If your body can’t do this well enough, you will have a reaction.

Alcohol Intolerance vs. Alcohol Allergy

Alcohol has long been a staple in social gatherings, celebrations, and even in some medicinal practices. However, many people are unaware of the surprising connection between alcohol and allergies. In this blog post, we will explore how alcohol can trigger allergic reactions, what symptoms to look out for, and how you can manage these reactions. By understanding this connection, you can make informed decisions about alcohol consumption and protect your health.

If you suspect a sulfite allergy, consider consulting an allergist for testing and avoid alcohol with high sulfite content, such as red wine. However, people with alcohol intolerance often have a genetic variant that causes ALDH to work less effectively. As a result, acetaldehyde builds up in their body, leading to uncomfortable symptoms. This accumulation can cause facial flushing, nausea, rapid heartbeat, and headaches – the telltale signs of alcohol intolerance. If you have symptoms after drinking beer, but not after drinking wine or other alcoholic beverages, it’s not alcohol intolerance.

Why am I allergic to beer?

Another enzyme, aldehyde dehydrogenase (ALDH), then allergies after drinking alcohol turns acetaldehyde into non-toxic acetic acid (vinegar). What we understand as a ‘hangover’ is made up of a particular set of symptoms – usually a thumping headache, nausea, intense thirst, tiredness and brain fog. This is all happens as a result of drinking alcohol, or more specifically, the series of bodily processes it sets in motion.

Examples of conditions that can cause alcohol intolerance or sensitivity are outlined below. Because the condition is inherited, there is no way to cure or treat it. Your healthcare provider can recommend ways to limit unpleasant symptoms. 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. Alcohol allergies are rare, but if you do have one, it doesn’t take much to trigger a reaction.

Alcohol intolerance is a problem with the specific enzyme that helps your body metabolize alcohol. Even drinking a small amount of alcohol (ethanol) causes unpleasant symptoms. Your face may turn pink or red (alcohol flush) and feel warm. Most people who have a reaction to alcohol aren’t allergic to it. They don’t have one of the active enzymes needed to process alcohol — alcohol dehydrogenase (ADH) or aldehyde dehydrogenase (ALDH).
