Introduction

Skin itching after drinking alcohol may be due to an allergy to alcohol. It could also result from an allergic reaction to mold (Aspergillus) used in the brewing process. Individuals with such alcohol allergies may develop itchy rashes after drinking, with severe swelling around the lips and eyelids, and edema spreading to the limbs. Any type of alcoholic beverage can trigger itching symptoms. However, for those allergic to Aspergillus or its byproducts, symptoms vary depending on the specific type of Aspergillus involved.

It is quite common for people to experience itchy skin after drinking alcohol. Many individuals develop red, itchy skin following alcohol consumption. So, what causes skin itching after drinking?

What Causes Skin Itching After Drinking Alcohol?

Skin itching after drinking may be due to an alcohol allergy. It could also result from an allergic reaction to mold (such as Aspergillus) used in the brewing process. Individuals with a true alcohol allergy may develop itchy rashes after drinking, with severe symptoms including swelling of the lips, eyelids, and even limbs. People allergic to alcohol will experience itching regardless of the type of alcoholic beverage consumed, whereas those allergic to Aspergillus or its byproducts may have varying reactions depending on the specific type of mold involved.

Skin itching after drinking may also stem from poor alcohol tolerance. Alcohol itself has a vasodilatory effect on the body. After drinking, some individuals experience facial flushing, sweating, and skin congestion. Those with low alcohol tolerance may find that even small amounts of alcohol cause widespread blood vessel dilation. This can lead to blood leaking from capillaries into the surrounding subcutaneous tissues, stimulating superficial nerve endings and causing itchiness.

To prevent skin itching after drinking, avoid consuming alcohol on an empty stomach. Drinking without food can cause significant harm to the heart, and alcohol is absorbed more quickly under such conditions. Eating something before drinking and having a warm soup afterward can help protect the stomach and intestines and reduce the risk of alcohol-related allergic reactions.
