Food allergies occur when the immune system mistakenly identifies certain foods as harmful and triggers an allergic reaction. The symptoms of a food allergy can range from mild to severe and may appear shortly after consuming the allergenic food. Here are common symptoms of a food allergy:
Skin reactions:
Hives (raised, itchy, red welts on the skin)
Itchy rash
Swelling of the face, lips, tongue, or throat (angioedema)
Eczema flare-up (itchy, red, and inflamed skin)
Gastrointestinal symptoms:
Nausea or vomiting
Abdominal pain or cramps
Diarrhea
Respiratory symptoms:
Runny or stuffy nose
Sneezing
Coughing
Wheezing or shortness of breath
Chest tightness
Oral symptoms:
Itchy or tingling sensation in the mouth, lips, or throat
Swelling of the lips, tongue, or throat
Hoarse voice
Cardiovascular symptoms:
Rapid heartbeat
Drop in blood pressure
Dizziness or lightheadedness
In severe cases, a food allergy can lead to a severe allergic reaction called anaphylaxis. Anaphylaxis is a medical emergency and requires immediate medical attention. Symptoms of anaphylaxis may include difficulty breathing, loss of consciousness, a sharp drop in blood pressure, and severe swelling.
It’s important to note that these symptoms can vary from person to person, and even small amounts of the allergenic food can trigger a reaction. If you suspect you have a food allergy or have experienced an allergic reaction after consuming a particular food, it’s essential to consult with an allergist or healthcare professional for proper diagnosis, management, and guidance on avoiding allergenic foods.
