Asthma is defined as chronic inflammatory disorder of the airways, characterised by reversible airway narrowing with obstruction of airflow to the lungs. Asthma is very common, affecting 1 in 4 children, 1 in 7 teenagers and 1 in 10 adults in Australia.
Individuals with asthma have hyper-responsive airways, which overreact to stimuli that do not affect other people. During an acute episode of asthma or an “asthma attack” exposure to a trigger causes three main changes to occur within the airways: the lining of the airways become inflamed and swollen, the thin layer of muscle within the wall of the airways constrict and excessive mucous is produced. The airway narrows, and causes individuals to experience one or more of the following symptoms.
shortness of breath
difficulty with breathing
a feeling of tightness in the chest
a persistent, dry, irritating cough
Allergens are by far the most common of asthma triggers, with over 80% of asthma sufferers having underlying allergies. Allergic asthma is usually caused by the inhalation of such aeroallergens as dust mites, pollens, moulds and animal dander. Food allergies can also stimulate the onset of asthma symptoms in susceptible individuals.
At Allergy First Gold Coast and Allergy First Brisbane we provide the Allergy Tests for those potential Asthma triggers (Aeroallergens).
