🟢 Introduction
Peanut allergy is one of the most common and serious food allergies globally. It occurs when the immune system mistakenly identifies peanut proteins as harmful, triggering an allergic reaction that can range from mild symptoms to severe, life-threatening conditions like anaphylaxis.
Even a tiny amount of peanuts can provoke a reaction in sensitive individuals, making awareness and prevention crucial.
🥜What Is a Peanut Allergy?
A peanut allergy is an immune system overreaction to proteins found in peanuts. Normally harmless, these proteins are treated as dangerous invaders, leading to the release of chemicals such as histamine that cause allergy symptoms.
🔎 Important note:
Peanuts are legumes, not tree nuts, although both can trigger allergic reactions.
🔴 Symptoms of Peanut Allergy
Symptoms usually appear within minutes after exposure but may vary in severity.
Mild to Moderate Symptoms:
- Skin rash or hives
- Itching or tingling in the mouth
- Swelling of lips or face
- Abdominal pain, nausea, or vomiting
- Runny nose or sneezing
Severe Symptoms (Anaphylaxis):
- Difficulty breathing
- Swelling of throat and tongue
- Drop in blood pressure
- Rapid pulse or dizziness
- Loss of consciousness
⚠️ Anaphylaxis is a medical emergency and requires immediate treatment with epinephrine.
🟡 Causes of Peanut Allergy
The exact cause is not fully understood, but it involves:
- Immune system misidentification of peanut proteins
- Release of antibodies (IgE) and chemicals like histamine
- Exposure through:
- Eating peanuts
- Cross-contamination
- Inhalation of peanut particles
