An allergy is a reaction the body has to a particular food or substance.
They're particularly common in children. Some allergies go away as a child gets older, although many are lifelong. Having an allergy can be a nuisance and affect your everyday activities, but most allergic reactions are mild and can be largely kept under control. More information around allergies can be found here.
Common symptoms of an allergic reaction include:
- sneezing and an itchy, runny or blocked nose (allergic rhinitis)
- itchy, red, watering eyes (conjunctivitis)
- wheezing, chest tightness, shortness of breath and a cough
- a raised, itchy, red rash (hives)
- swollen lips, tongue, eyes or face
- tummy pain, feeling sick, vomiting or diarrhoea
- dry, red and cracked skin
