Dr Harsha Kariyawasam

Consultant Allergist

I am a Consultant in Allergy and Respiratory Medicine, I am a national expert in hay fever. I have expertise in all things medical associated with the nose and sinuses. I lead the medical rhinology service in the Specialist Allergy and Clinical Immunology Department at the Royal National ENT Hospital, London, part of one of the largest such services in the UK.

Nasal allergy (termed allergic rhinitis or commonly hay fever) is my especial area of expertise. I am the proud author of the treatment section of the National Guidelines for the treatment of rhinitis recommended by the British Society of Allergy and Clinical Immunology. I lecture at national and international levels on this medical condition conducting research that focuses on the immunology and mechanism of nasal allergy.

The aim of this website is to help sufferers of hay fever towards obtaining a definite diagnosis and starting an appropriate and effective treatment.

In my practice as a hay fever expert, year after year I find many patients have not had the correct diagnosis and therefore compelled to live suffering with annoying and troublesome symptoms.

In the next pages I have put together important information to help individuals recognise and understand hay fever. Sufferers can learn to avoid what triggers their hay fever and find the right treatment, after all everyone deserves to enjoy spring and summer.
