What is a peanut allergy?
A peanut allergy is an overreaction of the immune system to peanut proteins, which can lead to mild or severe symptoms, including anaphylactic shock.
This condition requires complete avoidance of peanuts and close medical monitoring to prevent complications.
Causes of a peanut allergy
A peanut allergy results from the immune system's reaction to certain proteins, including:
- Early exposure to peanuts in children prone to allergies.
- A family history of food allergies.
- The presence of other autoimmune diseases such as asthma or eczema.
- Reaction to very small amounts of peanuts or peanut products.
Symptoms of a peanut allergy
Symptoms vary depending on the severity of the allergy, and some of the most prominent include:
- Itching, rash, and redness.
- Swelling of the lips, face, or throat.
- Difficulty breathing or wheezing.
- Nausea, vomiting, and abdominal pain.
How to diagnose a peanut allergy
Diagnosis involves several methods to determine the type and severity of the allergy, such as:
- Skin testing by applying drops of peanut extract.
- Blood tests to detect antibodies.
- Clinical assessment of the patient's history of symptoms and previous reactions.
- Sometimes a food challenge test under medical supervision.
Treatment for Peanut Allergy
Treatment for peanut allergy focuses on prevention and symptom control, including:
- Completely avoiding peanuts and peanut products.
- Carrying emergency medications such as an epinephrine auto-injector.
- Antihistamines to relieve itching and mild symptoms.
- Regular medical follow-up to monitor the treatment response.
When to See a Doctor?
You should see a doctor immediately if you experience any allergic symptoms after eating peanuts, especially if accompanied by throat swelling or difficulty breathing, as these are signs of a life-threatening anaphylactic shock that requires immediate medical attention.

- Reading food labels carefully to avoid peanuts.
- Teaching children and adults with peanut allergies to avoid contaminated foods.
