Facial Flushing and Redness
Facial flushing usually develops within minutes of drinking alcohol and can occur even after a small amount. The face turns red and warm due to an increased blood flow as the result of dilated capillaries.
Stomach Pain and Nausea
People with an alcohol allergy often experience stomach pain and nausea. These painful cramps and discomfort can develop soon after consuming alcohol and persist for several hours.
Rapid Heartbeat
Following alcohol ingestion, an individual may experience tachycardia, a condition where the heart rate exceeds the normal resting state. This can induce feelings of discomfort or unease.
Shortness of Breath
Difficulty breathing or shortness of breath after alcohol consumption is another symptom of an alcohol allergy. It is typically accompanied by a tightness in the chest and can be a sign of a severe reaction that requires immediate medical attention.
Skin Reactions
Generalized skin reactions such as hives, inflammation, or rash can occur. These may itch, sting, or burn and may be localized to certain areas or spread across the body.
Nasal Congestion
Alcohol allergy can cause nasal congestion, leading to a runny nose or sinus congestion. These symptoms are due to the dilation of blood vessels in the nasal cavity, which is a common allergic reaction to alcohol.
