Allergies commonly run in families, and these are referred to as ‘atopic’. Such families have higher than average incidences of asthma, eczema, hayfever and food allergies.
Visiting your GP
Allergy UK has the following advice when it comes to helping your doctor diagnose your child: try to think of when your child started having symptoms and note the date, time of year and how long they lasted. Think back to your child’s diet and what activities they were doing, and try to record all these details so the doctor can get a clear picture of what has happened. Some doctors may give you a symptom diary to fill in, where you can record all this information, as these clues can lead to a quicker diagnosis. For more information, read the childhood food allergy information published by Allergy UK.
Once your GP has completed their assessment, they will recommend the next course of action – this may be referral to a specialist, an allergy test or an elimination diet. If your child needs either of the latter approaches, it is important that they be performed by an appropriate healthcare professional with the competencies to select, perform and interpret the results and/or guide you through any dietary changes. Speak to your GP or a registered dietician for advice.
Allergies and food groups
Foods can be grouped into problem families that might not seem immediately obvious. For instance, some foods have similar proteins to pollen, such as kiwi, apples, potatoes and soy beans. This means that if someone has hay fever, they may react to these foods due to a cross-reaction of similar compounds, referred to as pollen food syndrome or oral allergy syndrome. This can make diagnosis of what’s causing the problem difficult unless symptoms are very obvious.
Cow’s milk allergy is one of the most common to affect babies and young children, and probably one of the most awkward. Thankfully, by the time most children start school, they should have outgrown their milk allergy, although for a small number the allergy stays with them into adulthood. Any immediate reactions to milk requires medical action, as it can be severe. Going dairy-free can mean making changes for the whole family. This may sound daunting, but read our spotlight on dairy-free diets for advice on ingredients and how to make dairy-free swaps.
An egg allergy is more common in children than adults and can cause severe symptoms, but thankfully most children grow out of it. A child’s allergy to egg may be quite specific, such as to raw egg only or to all forms of egg (cooked, loosely cooked and raw) – this emphasises the importance of seeing an allergy specialist so that unnecessary foods or ingredients are not eliminated from the diet.
An allergy such as a peanut or tree nut allergy, can be severe and lifelong. If your child is living with a peanut and/or tree nut allergy, our spotlight on nut-free diets gives an overview of nut allergies, including foods to avoid, how to read labels and suggested recipes to try. If you suspect your child has a peanut or tree nut allergy, you should consult your GP immediately.
Your GP or healthcare professional will advise on the best course of action, which may include:
- Total avoidance of the allergen
- Antihistamines to use when the reaction is mild
- Adrenaline, such as the EpiPen, Emerade and Jext – brand names of adrenaline auto-injector devices available in the UK. These are used for severe reactions and can be lifesaving for inadvertent exposure to food allergens
In a number of instances (such as hay fever, asthma and eczema) you can try making changes to your diet and lifestyle to reduce the overall allergenic ‘load’ placed on the immune system. This may help to improve overall quality of life, although you would still need to avoid the food to which you are allergic
