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.
Why do my cheeks turn red when I drink alcohol?

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.”
Why are my cheeks always red not rosacea?
Why cheeks turn red – Rosy cheeks can happen for a range of reasons. When you’re outdoors in cold weather, for example, your blood vessels widen to let more blood into your face, leading to that redness. Embarrassment can bring on similar redness, in the form of blushing.
Why do my cheeks get red and hot?
What is a flushed face? – A flushed face or blushing is the sudden reddening of the face, which can also affect the neck and upper chest, The redness can manifest as red patches or blotchiness, and is caused by increased blood flow to the face, causing blood vessels to enlarge. The enlarged blood vessels cause the face to go red. A flushed face is often the result of anxiety, stress, embarrassment, or even spicy foods, but it could also be the result of an underlying medical condition, such as rosacea, Cushing’s disease, or a niacin overdose, If you experience recurring, unexplained flushing, seek medical attention.
How do you prevent rosacea when drinking?
Alternate Your Drinks With a Glass of Water – Alcohol is a diuretic and promotes urination, so there’s the risk of dehydration from too much alcohol, according to the NHS, And Young says that dehydration can lead to skin sensitivity and compromise the skin’s barrier. Also, “rosacea-affected skin tends to be dehydrated at baseline,” Mudgil continues.
The more dehydrated the skin gets, the more prone it is to flaring. Since alcohol is dehydrating, it’s important to be mindful of your hydration status when you have rosacea.” How can you combat this? Consuming a glass of water between drinks helps dilute the alcohol and prevent some of the pH changes in your system, says Lupo.
In addition, Mudgil says, “Alcohol pushes our body into an acidic state, which is thought to be pro-inflammatory. Drinking water helps to balance the body and draw it closer to an alkaline state, which is anti-inflammatory.” Everyone’s water needs are different, but 2014 recommendations from the National Academy of Sciences, Engineering, and Medicine advises sipping between ½ ounce (oz) to 1 oz of fluid, which includes water, for each pound of body weight you have.
Does drinking water reduce red cheeks?
Drinking water can definitely help limit the symptoms of rosacea. However, it may not fix everything, but it can go a long way in reducing redness. Your body is mostly made up of water, and by drinking enough every day, you help flush out toxins on your skin and in your body.

- In many cases, the cheeks blush for benign reasons, such as trying to warm the skin up in cold conditions.
- However, they can sometimes signify a more severe condition.
- It is important for a person to know the potential causes of rosy cheeks and the other symptoms that may occur alongside them.
