Asthma: Causes, Symptoms, and Management

Understanding Asthma

Asthma is a chronic condition in which the airways become inflamed and narrowed, making breathing difficult. It affects people of all ages and can range from mild to severe.

What Causes Asthma?

The exact cause of asthma is not fully understood, but it involves a combination of genetic predisposition and environmental factors. Common triggers include allergens (pollen, dust mites, pet dander, mould), respiratory infections, cold air, exercise, air pollution, tobacco smoke, and strong emotions or stress.

Recognising the Symptoms

Asthma symptoms vary from person to person but commonly include wheezing (a whistling sound when breathing), shortness of breath, chest tightness, and coughing — especially at night or early in the morning. Symptoms may flare up during an asthma attack, when the airways constrict suddenly and significantly.

How Asthma Is Managed

While there is no cure for asthma, it can be effectively managed with the right treatment plan. This typically includes controller medications (such as inhaled corticosteroids taken daily to reduce inflammation) and reliever medications (such as short-acting bronchodilators used during flare-ups). An asthma action plan, developed with your healthcare provider, outlines what to do when symptoms worsen. Identifying and avoiding personal triggers is also essential.
