Identifying symptoms quickly is essential in managing food allergies. These symptoms vary from mild to severe:

Mild Symptoms:

• Redness around the mouth or eyes

• Mild swelling of the lips or face

• Slight discomfort or fussiness

• Aversion/dislike of the food just eaten

Moderate Symptoms:

Mild symptoms and:

• Vomiting or diarrhoea shortly after eating

• Persistent coughing or wheezing

• Altered behaviour, e.g. noticeable irritability or prolonged restlessness

• Nasal symptoms include congestion or a runny nose, often accompanied by profuse nasal discharge and repeated sneezing.

Severe Symptoms (Anaphylaxis):

A combination of the above symptoms and:

• Generalised pink/red colour with hives, intense scratching.

• Difficulty breathing, noisy or wheezing breath, altered voice, wheezy cough or wheezing

• Severe swelling, especially of the face, lips, digits or tongue

• Weakness, limpness, lethargy, or unusual, sudden-onset sleepiness

• Intense abdominal pain

• Pale or bluish skin colour

• Loss of consciousness, floppy or suddenly sleepy.

If severe symptoms arise, immediately treat them as an emergency and seek medical assistance without delay.

Immediate Actions: Detailed Step-by-Step Guide

Acting quickly and clearly is crucial when a baby shows signs of an allergic reaction. Follow these immediate, practical steps:

Stay Calm & Remove the Allergen:

• Immediately discontinue feeding the suspected allergenic food.

• Gently and carefully clean your baby's face and mouth with a soapy, damp cloth or a wet wipe to remove any traces of the allergen.

Administer Prescribed Medication Promptly:

• Give your baby an antihistamine if previously prescribed by your paediatrician for mild reactions, strictly following dosage instructions. If your baby vomits, repeat the dose.

• In cases of severe reactions, immediately administer an epinephrine auto-injector (such as an EpiPen or Neffy nasal adrenaline device when available), if your doctor has prescribed one.

Monitor Your Baby’s Condition Closely:

• Watch your baby’s breathing, skin, behaviour, and responsiveness carefully to detect any worsening symptoms promptly.

Call Emergency Services Immediately if Symptoms Intensify:

• If your baby’s symptoms escalate or you notice breathing difficulty, call emergency services (999 in the UK or 911 in the USA) without hesitation.

When to Seek Emergency Help

Anaphylaxis is a severe and potentially life-threatening allergic reaction that requires immediate medical intervention. According to the NHS, if your baby exhibits severe symptoms such as difficulty breathing, severe swelling, or faintness, emergency services must be called immediately. Rapid response can save lives, and every second counts.

Aftercare: Essential Steps After an Allergic Reaction

Once your baby is stabilized and safe after an allergic episode, consider these important follow-up actions:

• Schedule an appointment with an allergist or pediatrician to accurately identify and confirm the allergen through London Food Allergy Testing.

• Create a detailed allergy management plan in collaboration with healthcare providers, tailored specifically to your baby’s needs.

• Educate all caregivers, babysitters, family members, and anyone regularly involved in your baby's care about recognizing allergy symptoms and responding effectively.

• Always keep prescribed medications accessible and inform caregivers where these medications are located.

Preventing Future Allergic Reactions

Proactive measures can significantly lower the risk of future allergic episodes:

• Introduce potential allergenic foods carefully and gradually, one at a time, monitoring closely for reactions.

• Maintain a detailed food diary to help identify triggers quickly.

• Regularly consult and update your approach with pediatric allergy specialists, such as those at London Allergy Consultants, ensuring your allergy treatment strategies remain effective and current.

• Educate yourself continuously about the latest developments and recommendations in allergy prevention and treatment.

Frequently Asked Questions:

• What foods commonly cause allergies in babies?

  Common allergenic foods for babies include milk, eggs, sesame, peanuts, tree nuts, wheat, soy, fish, legumes and shellfish.

• Can babies outgrow food allergies?

  Many babies outgrow allergies to milk, eggs, wheat, and soy by the time they enter school i.e. at around 6 years of age. However, allergies to these foods may persist in some patients, and in most patients, allergies to peanuts, tree nuts, fish, and shellfish typically persist into adulthood.

• How quickly can an allergic reaction occur?

  Allergic reactions usually appear rapidly, within minutes, and usually within the first hour. After initial symptoms, eczema may flare over hours.

• Should allergenic foods be completely avoided for babies?

  No, current guidelines recommend early introduction of allergenic foods around 4-6 months of age. Studies such as the LEAP and EAT Studies, which Dr’s Du Toit and Dr Foong were involved with, have led to these dietary changes. Feel free to consult with them to get the very latest advice in this regard. There is a Blog on this topic on this website.

• How are food allergies diagnosed in babies?

  Allergists typically use clinical history (if previously exposed to the allergen) skin prick tests, blood tests, elimination diets, and supervised food challenges to accurately diagnose food allergies.
