Ask the Researcher: Sulphite Allergy

Have you ever done any research on asthma and sulphite allergies? Have you heard of these two being related?

Sulphite sensitivity has been extensively studied.  Although rare, it is more frequently associated with severe asthma. Sulphite allergy is rarely associated with a rash. An allergist can help determine if symptoms are caused by a sulphite allergy by doing a "sulphite challenge".  During a sulphite challenge, the allergist will give the patient some foods with sulphite and observe the patient's response. This can help identify the casue of the symptoms the patient is experiencing.
