Signs and Symptoms of Peanut Allergies

When a child with a peanut allergy consumes or comes into contact with peanuts, they may experience a range of symptoms, such as:

  • Itchy skin, hives, or redness
  • Swelling of the face, lips, or tongue
  • Difficulty breathing or wheezing
  • Stomach pain, nausea, or vomiting
  • Dizziness or fainting

In severe cases, a child may experience anaphylaxis, a life-threatening reaction that requires immediate medical attention.

Diagnosing Peanut Allergies in Children

If you suspect your child has a peanut allergy, consult with an allergist or pediatrician. They will perform a series of tests, including a skin prick test, blood test, or oral food challenge, to confirm the diagnosis.

Managing and Treating Peanut Allergies

There is no cure for peanut allergies; however, parents can take several steps to manage their child’s allergy:

  • Educate your child about their allergy and the importance of avoiding peanuts and products containing them.
  • Read food labels carefully to identify potential allergens and hidden sources of peanuts.
  • Create an allergy action plan with your child’s healthcare provider, including instructions on administering emergency medication such as an epinephrine auto-injector (EpiPen).
  • Inform caregivers, teachers, and other adults in your child’s life about their allergy and the necessary precautions.
  • Encourage your child to carry their EpiPen and wear a medical identification bracelet or necklace.

Preventing Peanut Allergies: What We Know So Far

Research has shown that early introduction of peanuts in an infant’s diet may help reduce the risk of developing peanut allergies. Consult your pediatrician for guidance on when and how to introduce peanuts to your child safely.

Living with a Peanut Allergy: Practical Tips

Children with peanut allergies can lead normal lives by following some practical guidelines:

  • Teach your child to politely refuse food from others unless they are sure it’s safe.
  • Keep safe snacks on hand for your child to enjoy at parties or events where peanuts may be present.
  • Be cautious when dining out, as cross-contamination can occur in restaurant kitchens.
  • Educate your child’s friends and their parents about the allergy and the necessary precautions.
