In this section you will find information on all types of allergy, such as hay fever, food allergy and house dust mite allergy. If you want to know “What are the symptoms of allergies?” or “What treatments might my doctor give me?”, this section may be able to help you find the answer.  It also covers conditions related to the blood and blood components such as anaemia and blood cancers like leukaemia, lymphoma and myeloma as well as inherited conditions such as sickle cell anaemia and thalassaemia.  You can read all about the symptoms and check the available treatments in our doctor-authored leaflets.
