Facebook Twitter LinkedIn Table of Contents Ever wondered why a dusty room can leave one person perfectly fine while another starts coughing and wheezing? Or why exercise, cold air or even a strong perfume can suddenly make breathing harder? The answer may lie in understanding asthma causes and triggers. Asthma is more than occasional breathlessness and knowing what affects your airways can make it easier to recognise symptoms, seek the right care and manage the condition.

In this blog, we’ll explore asthma causes and triggers, common symptoms, who may be at greater risk, what happens during an asthma attack, how asthma is diagnosed and treated, and practical ways to manage it every day. We’ll also tackle some common asthma misconceptions and look at when breathing difficulties require urgent medical attention. What is Asthma? First question: What actually happens when someone has asthma? Asthma is a chronic condition that affects the airways, the tubes that carry air into and out of the lungs. When asthma symptoms occur, the airways can become inflamed and narrowed, while the muscles around them tighten. Some people may also produce more mucus. Together, these changes can make it harder for air to move freely. The result? Wheezing Coughing Shortness of breath Chest tightness These symptoms can come and go. Some people experience them occasionally, while others may have persistent or more severe symptoms. And asthma isn’t limited to one age group. Children, teenagers and adults can all develop asthma. It cannot currently be cured, but appropriate treatment and ongoing management can help control symptoms and allow many people to lead active, everyday lives. Asthma affects 363 million people globally, with around 442,000 deaths recorded in 2023, according to the WHO. In the Caribbean, approximately 496,235 people were living with asthma in 2021, with around 3,360 asthma-related deaths and 2.03 million DALYs reported. Country-level estimates also show asthma prevalence of 9.2% in Barbados, 9.1% in Jamaica and 8.7% in Guyana, highlighting the continuing respiratory health burden across the region. FACT CHECK Q: Is asthma simply “having weak lungs”? A: Not quite. Asthma involves inflammation and variable narrowing of the airways. Its symptoms can fluctuate considerably over time, which is one reason identifying individual patterns and triggers matters. What Causes Asthma? Is there one single cause of asthma? No. There isn’t one universal explanation for why someone develops asthma. Instead, a combination of genetic, environmental and immune-related factors may contribute. A family history of asthma can increase the likelihood of developing the condition. People with allergic conditions such as eczema or hay fever may also have a higher risk. Environmental exposures can matter too. These may include: Air pollution Tobacco smoke Dust mites Mould Pollen Animal allergens Chemical fumes Workplace dust and irritants Respiratory infections Early-life factors and recurrent viral respiratory infections may also influence asthma risk. This brings us to an important distinction. Cause vs trigger: Are they the same thing? No. A cause or risk factor may contribute to someone developing asthma. A trigger, on the other hand, is something that can provoke or worsen symptoms in someone who already has asthma. That distinction is important when thinking about asthma causes and triggers. Common Symptoms of Asthma Could that persistent cough actually be asthma? It could be, but coughing alone doesn’t automatically mean someone has asthma. Common symptoms include: Wheezing – a whistling or squeaky sound when breathing, particularly when breathing out Coughing – asthma-related coughing may be particularly noticeable at night or early in the morning Shortness of breath – you may feel unable to get enough air or find yourself becoming unusually breathless Chest tightness – some people describe this as pressure, heaviness or a feeling that their chest is being squeezed Symptoms can vary considerably in frequency, intensity and duration. They may become more noticeable at night, during exercise, during respiratory infections or after exposure to certain triggers. FACT CHECK If symptoms disappear, does that mean asthma is gone? Not necessarily. Asthma symptoms can fluctuate. A person may feel completely well between episodes while still having underlying airway inflammation or a tendency towards variable airflow limitation. If recurring respiratory symptoms are affecting your sleep, exercise or everyday activities, speaking with a healthcare professional is important.

Can something as ordinary as dust or cold air really trigger asthma? Yes. Triggers are different for different people. One person’s trigger may barely affect someone else. Common triggers include: Trigger How It May Affect Asthma Dust and dust mites Can irritate or provoke allergic airway responses Pollen May trigger symptoms in people with pollen allergies Mould Can act as an allergen or airway irritant Pet dander May provoke symptoms in people who are sensitive to animal allergens Smoke and air pollution Can irritate and inflame the airways Strong smells & chemical fumes Perfumes, cleaning products and workplace chemicals may trigger symptoms Respiratory infections Colds and other viral infections can worsen asthma Cold air/weather changes Sudden environmental changes may provoke symptoms Exercise Can trigger symptoms in some people, particularly when asthma is not well controlled Stress and strong emotions Emotional stress can contribute to worsening symptoms These are all
