Food allergy, also known as food intolerance and food hypersensitivity is caused when the body’s immune system finds a food item as harmful and reacts by causing symptoms. Some of the most common symptoms of food allergy including abdominal pain, vomiting, diarrhoea, itching, swelling, sneezing, cough, etc. Foods that cause allergic reactions are known as allergens. In Australia, food allergy occurs in around 1 in 20 children and in about 2 in 100 adults. Peanuts, cow’s milk, egg, fish, shellfish, seafood, wheat are some of the common food items that cause allergies.
Some food allergies can be very severe and may lead to life-threatening reactions known as anaphylaxis. The signs of severe allergic reaction to foods can be difficult breathing, swelling in throat, swelling of tongue, hoarse voice, persistent dizziness, wheeze, pale and floppy, etc. The life-threatening situation from food allergies can be prevented by careful allergen avoidance measures and immediate administration of an adrenaline autoinjector.
A food allergy test in Australia such as hair analysis test, Skin prick test, blood test, etc., can be really useful to confirm the suspected allergies to foods, so that appropriate avoidance steps can be taken.
