DEFINITION

Peanut allergy is a common cause of severe allergic reactions. Symptoms can range from mild to life-threatening, requiring immediate medical attention.

SYMPTOMS

Symptoms of peanut allergy can include runny nose, skin reactions, itching in the mouth and throat, digestive issues, and more severe symptoms like tightening of the throat and difficulty breathing.

Anaphylaxis: A life-threatening reaction

WHEN TO SEE A DOCTOR

CAUSES

Peanut allergy occurs when the immune system mistakenly identifies peanut proteins as harmful and releases chemicals that cause allergic reactions. Exposure can happen through direct contact, cross-contact, or inhalation.

RISK FACTORS

Risk factors for developing peanut allergy include age (more common in children), past allergies to peanuts, other allergies, family history of allergies, and conditions like atopic dermatitis.

COMPLICATIONS

Complications of peanut allergy can include anaphylaxis, especially in individuals with severe allergies.

Being prepared for a reaction

Carrying an epinephrine autoinjector at all times and knowing how to use it is crucial for individuals with peanut allergies.
