There are a number of different types of allergies out there. You can find out more about them here at Piri Allergy.

Brief episodes of airborne allergies


(Intermittent allergic rhinitis)

Hay fever is an example of this type of allergy. It is triggered by airborne allergens such as pollen during spring, summer and autumn. Grass pollen is considered to be the most common cause of hay fever in the United Kingdom.

Conditions like global warming are leading to longer growing seasons, which have led to a rise in the number of hay fever sufferers.

Urticaria or hives

Hives on skin

This condition is characterised by raised red skin welts, also known as nettle rash. This rash may appear anywhere on the face or body and is accompanied by itching. It is caused by direct contact with the allergen or due to an immune response to a food substance.







Allergic contact dermatitis
