About 44 million people in the Asia Pacific region suffer from asthma. The numbers are on the rise especially in China and India where there is rapid industrialisation and urbanisation. Dr Mariko Koh, Director of the Pulmonary Function Laboratory and Asthma Programme at Singapore General Hospital, tells us more about adult asthma:
 Asthma explained
1. Chronic inflammation of the airways
When the airways are inflamed, mucus forms, obstructing airflow, causing breathlessness, wheezing and tightness in the chest.
2. Common triggers
Exposure to allergens such as dust mites, cockroaches, pets and pollen can trigger asthma. Tobacco smoke, respiratory infections, exercise and some medications like aspirin and beta blockers are also possible triggers.
3. There is no cure
There is no cure but asthma can be controlled with medication. The mainstay of asthma treatment is inhaled corticosteroids to reduce inflammation and obstruction of the airways. Reliever medications may be used to treat acute symptoms. Take note: It is not too late to take medication after an asthma attack.
4. Take medication daily
To ensure good control over asthma, medication must be taken daily on a long term basis to prevent attacks. Also, go to your doctor for regular checkups.
5. Quality of life
Asthma sufferers can lead a normal active life as long as the symptoms are well controlled. Taking medication as directed and avoiding triggers can make a big difference to their quality of life.
