The World Health Organization (WHO) estimates that there are currently about 235 million people worldwide who suffer from asthma, and that in 2016 there were 383 000 deaths due to this disease.

Controlling asthma

An asthma attack occurs when the lining of the bronchial tubes swell. This causes the airways to narrow, which reduces the airflow in and out of the lungs.

According to the WHO the strongest risk factors for asthma are a combination of genetic predisposition with environmental exposure to inhaled substances and particles.

Asthma can be controlled with the help of medication and by avoiding triggers that irritate and inflame the airways.  

How severe is your asthma?

The treatment of your asthma is based on your severity level. This means that your doctor will assess and classify the severity according to the latest guidelines for the management of asthma in either adults and adolescents or children.

Asthma treatment involves a two-pronged approach: targeting chronic airway inflammation and relieving acute bronchial spasms.

Determining the severity

The following tables will help you (and your doctor) determine the severity of your or your child's asthma symptoms:
