Asthma

Asthma is a long-term condition where the airways become inflamed and narrow, making breathing harder. It usually shows up as wheezing, a tight chest, breathlessness and a cough that often gets worse at night or with exercise. Symptoms come and go, and a sudden worsening is called a flare-up or attack. With the right routine, most people keep asthma well controlled and stay active.

What triggers asthma

Triggers vary from person to person. Common ones include dust mites, pollen, pet dander, cold air, chest infections, smoke and exercise. Across much of Asia, two factors stand out: high outdoor air pollution in cities like Bangkok, Jakarta, Delhi and Manila, and the seasonal haze that drifts over Singapore, Malaysia and Indonesia. Humid indoor conditions also favour dust mites and mould, both frequent culprits. Knowing your own triggers and reducing exposure where you can makes day-to-day control easier.

How asthma is treated

Treatment usually pairs two kinds of inhaler. A reliever such as salbutamol opens tight airways quickly during symptoms. A preventer, taken every day, lowers the underlying inflammation so flare-ups happen less often; these are inhaled steroids like budesonide, fluticasone and beclometasone. For asthma that needs more, a long-acting opener such as salmeterol is often combined with a preventer, and theophylline is used as an add-on in some cases. You can see the full range on our respiratory health pages.

When to seek help

See a doctor if you need your reliever more than a few times a week, if symptoms wake you at night, or if your usual inhaler is not easing an attack. Struggling to speak in full sentences, blue lips or a reliever that brings no relief are emergency signs and need urgent care.
