Have you ever had hay fever (allergic rhinitis), sinus problems (sinusitis) or been told by your doctor that your irritated nose and eyes are caused by allergy?
An itchy, runny or blocked nose due to allergies can make asthma harder to control.
Up to four out of five people with asthma also have hay fever (allergic rhinitis) - either at certain times of the year or all year round.
You may be asked about when your symptoms first started, whether they are worse at certain times of the year and if they have become better or worse over time.
Treating the symptoms in your nose and throat can also improve asthma symptoms.
Avoid your allergy triggers, if possible, but don’t forget to also take your medication. Common allergy triggers include pollen, house dust mites
