Alcohol intolerance Symptoms and causes

An alcohol allergy and alcohol intolerance are two different conditions. Alcohol intolerance can be caused by anything that affects the function of alcohol dehydrogenase. Incorrect function in alcohol dehydrogenase enzymes can be caused by genetic changes, chemical changes or heredity.

You may notice that even after alcohol intolerance a small amount of alcohol, you don’t feel great. These might be signs of alcohol intolerance, an inherited disorder. While there is no cure for this condition, avoiding alcohol helps you stay symptom-free. When people have alcohol intolerance, it’s because the ALDH2 enzyme is less active or completely inactive — the result of a genetic mutation. This mutation means that the harmful acetaldehyde will build up in the blood and tissues. This action is why people with alcohol intolerance will experience facial flushing. Rarely, severe pain after drinking alcohol is a sign of a more serious disorder, such as Hodgkin’s lymphoma.

Alcohol flushing syndrome is a major sign of alcohol intolerance. Your face, neck and chest become warm and pink or red right after you drink alcohol. But the hallmark symptom of alcohol intolerance is flushing of the skin of the chest, neck and face. People often confuse alcohol intolerance and alcohol allergy, but they aren’t the same condition. Alcohol intolerance is often mistaken for alcohol allergy, but the former is distinctly different from the latter. An allergy to alcohol occurs when your immune system overreacts to a drink, according to this Healthline report.

Other causes of intolerance to alcohol

Unfortunately, if the body can’t effectively process and break down these histamines, it creates a buildup, which can cause these uncomfortable skin conditions, he explains. You’ll have those same symptoms and a more intense reaction, wheezing, difficulty swallowing, low blood pressure, and heart palpitations, he says.
