Experiencing an Asthma Attack
People with severe asthma are at increased risk of asthma attacks. Asthma attacks are a significant worsening of asthma symptoms and lung function over time. Many people will experience multiple attacks over the course of the year, often requiring hospitalisation and oral corticosteroid treatment.
Attacks may result from a gradual worsening of asthma symptoms or following exposure to a disease trigger. They may develop slowly over hours days or weeks or very quickly. Exposures that may trigger attacks include allergen exposure (e.g. pollen) and lung infections.
