Food allergies are caused by an immune response by the body to a protein, or allergen, within the food that the body sees as threatening. The body releases histamine, which can lead to symptoms including vomiting, diarrhoea, rashes or breathing difficulties. Having a food allergy can be extremely unpleasant, and in some cases, life threatening, and having a diagnosis can be important in ensuring you remain well. At Touchwood Pharmacy we offer affordable, convenient food allergy testing appointments that you can book online with just a few clicks. Priced at £149, our experienced pharmacists can offer you advice that is priceless.
