Recognising asthma symptoms: A guide to early detection
Asthma is a common respiratory condition that affects the airways, making breathing more difficult. While many people are familiar with the more obvious symptoms, asthma can also present in less typical ways.
In this article, consultant in respiratory medicine and allergy Dr Raghu Raju outlines the key symptoms of asthma, how to recognise common triggers, and when to seek medical advice.
What is asthma?
Asthma is a chronic condition that causes inflammation and narrowing of the airways, making it difficult to breathe.
It can be triggered by allergens, respiratory infections, cold air, exercise, or irritants like smoke or pollution.
Key symptoms of asthma
Below are some of the most common symptoms that may indicate asthma, though they can vary in severity and frequency from person to person:
Breathlessness
Shortness of breath is one of the most recognisable symptoms of asthma. It may occur during physical activity, when exposed to triggers, or at night.
This sensation may come on suddenly or gradually worsen over time. It’s often described as feeling like you can’t get enough air.
Persistent cough
A frequent dry cough, particularly at night or early in the morning. This type of cough tends to linger and doesn’t improve with over-the-counter treatments.
In children, a persistent cough may be the only sign of asthma.
Wheezing
Wheezing is a high-pitched whistling sound when exhaling. It occurs as a result of narrowed airways and may be more noticeable during or after exercise or when exposed to pollen or dust.
Chest tightness
Asthma may also cause a feeling of tightness or pressure in the chest, which can feel quite distressing.
This may be worse after physical activity or during the night and can sometimes be mistaken for anxiety or heart issues.
Identifying patterns and triggers
Asthma symptoms often follow a pattern. You might notice they worsen in certain situations, such as:
- At night or early in the morning
- During or after physical activity
- In cold, damp, or windy weather
- After exposure to allergens (pollen, pet dander, dust mites or mould)
- Following a respiratory infection, like a cold or flu
- After exposure to smoke, pollution, or strong odours
Understanding your personal triggers is a vital step in managing asthma effectively.
When to seek medical advice
It’s important to seek medical advice if you or your child are experiencing any of the symptoms mentioned above, especially if they are frequent or interfering with daily life.
Early diagnosis can make a significant difference in how well the condition is controlled. In some cases, symptoms may escalate and require urgent medical attention.
Signs of an asthma attack include:
- Severe shortness of breath or rapid breathing
- Lips or fingers turning blue (cyanosis)
- Difficulty speaking due to breathlessness
- No improvement after using a reliever inhaler
These are signs of a serious asthma attack and should be treated as a medical emergency.
Recognising the early signs and understanding your personal triggers are key to managing asthma.
