What causes alcohol flush reaction? – Image The alcohol flush reaction is a type of alcohol intolerance—not an “alcohol allergy”—and is a condition predominantly due to inherited variations in genes of certain enzymes, causing people to metabolize alcohol less efficiently. During alcohol metabolism, the enzyme alcohol dehydrogenase (ADH) converts alcohol to acetaldehyde, a toxic molecule.
- The resulting acetaldehyde is metabolized to nontoxic molecules by another enzyme called aldehyde dehydrogenase (ALDH).
- If acetaldehyde is not metabolized efficiently, it can cause release of histamine and thereby trigger flushing and other unpleasant symptoms.
- Variations in the alcohol dehydrogenase gene, ADH1B, and the aldehyde dehydrogenase gene, ALDH2, are well-known variations that lead to higher acetaldehyde levels due to altered alcohol metabolism and are more common among people of East Asian ancestry.
People of other races and ethnicities, however, can also carry these variations. People who take certain medications that alter alcohol metabolism can also experience the alcohol flush reaction. Such medications include those used to treat diabetes, high cholesterol, and infections.

Is it bad if my face gets red when I drink?
Although this condition involves symptoms that are similar to allergies, it is important to understand that most cases of face reddening are not evidence of an allergy to alcohol. The genetic condition is a form of alcohol intolerance, and the effect it produces is referred to by clinicians as alcohol flush reaction.
Why do I get hot when I drink alcohol?
Effects on the heart and blood vessels – Alcohol affects the body in many ways, and this includes its effects on the heart. It can cause the heart rate to become too fast or the heart rhythm to become irregular, With alcohol intake, the blood vessels in the skin tend to widen when the heart rate speeds up.
This process is called vasodilation, Dilated blood vessels cause the skin to feel warm and flushed, which can trigger the release of sweat. This sweating could occur at any time of day. However, as many people drink alcohol in the evening, night sweats are common. While many people feel warm after drinking alcohol, the core body temperature drops as blood moves from the core to the skin through dilated blood vessels.
Sweat also removes heat from the body. People may not realize that because of this, they are at risk of hypothermia in cold weather. During hot weather, they may begin to experience nausea and dizziness with dehydration in addition to sweating.

Enzyme deficiency. Many Asian populations have a deficiency in alcohol dehydrogenase, the enzyme that breaks alcohol down. “Alcohol is toxic to cells, and when it gets into the cells of your blood vessels, it makes them dilate,” he says. “This reddens the skin and can make you feel warm.” Without enough of this enzyme, alcohol reaches toxic levels much earlier in your cells.
Rosacea. Fair-skinned people of Northern European backgrounds who flush when they drink may have some degree of rosacea. “This very common skin condition is marked by vasomotor instability or hyperactivity,” explains Dr. Vij. “That means lots of things can dilate your blood vessels: alcohol, chocolate, hot beverages and spicy foods — basically, all the good things in life.”

When should I be worried about a red face?
– Flushed skin occurs when the blood vessels just below the skin widen and fill with more blood. For most people, occasional flushing is normal and can result from being too hot, exercising, or emotional responses. Flushed skin can also be a side effect of drinking alcohol or taking certain medications.
What is the best thing to drink after being drunk?
Electrolyte solutions (such as sports drinks) and bouillon soup are good for replacing the salt and potassium you lose from drinking alcohol. Get plenty of rest. Even if you feel good the morning after heavy drinking, the lasting effects of alcohol reduce your ability to perform at your best.
