Asthma is a chronic condition that affects the airways in the lungs, making them inflamed and narrowed. This can lead to breathing difficulties, wheezing and coughing. Understanding what asthma is and its triggers is crucial in managing symptoms and preventing serious complications.
The condition can affect people of all ages and varies in severity. Some individuals experience only mild symptoms, while others may suffer from chronic asthma attacks or acute severe asthma.
With proper diagnosis, treatment and lifestyle modifications, it is possible to live a healthy and active life despite having asthma.
Recognising the symptoms is the first step in controlling the condition:
In people with exercise-induced bronchoconstriction (EIB), symptoms usually begin within minutes of starting activity and may peak 5–10 minutes after stopping.
People may experience only a persistent cough without other symptoms. Children with symptoms may appear to have frequent bronchitis or difficulty breathing during play.
An asthma attack (or acute exacerbation of asthma) occurs when symptoms worsen rapidly.
Asthma attack symptoms include severe shortness of breath, chest tightness and the inability to speak in full sentences.
These asthma triggers can vary from person to person. Genetic and environmental factors both play a role in the pathophysiology of asthma, especially in the development of inflammation and airway hyperresponsiveness.
Getting an accurate asthma diagnosis involves several steps to confirm the condition and rule out other causes of breathing difficulties. Since asthma symptoms can vary and mimic other respiratory issues, a thorough and multi-step evaluation is important:
A clear diagnosis not only confirms asthma but also helps develop a personalised treatment plan and identify lifestyle factors or environmental triggers that may worsen symptoms.
This form of asthma presents primarily with a chronic dry cough, often without the usual wheezing or shortness of breath. It may be worse at night, after exercise or when exposed to cold air or allergens.
Because the symptoms are subtle, it can often be mistaken for a lingering cough or post-nasal drip, leading to delays in diagnosis. If left unmanaged, cough-variant asthma can progress into classic asthma with more obvious breathing symptoms.
People with this form of asthma may feel fine most of the time and show no signs of wheezing, coughing, or breathlessness between flare-ups. However, their airways are still sensitive and may suddenly react to triggers like dust, smoke, exercise or illness.
This type of asthma can be risky because people may not realise their lungs are inflamed until a severe attack occurs. Regular check-ups and lung function tests are important for ongoing management.
This condition combines features of both asthma and chronic bronchitis. It involves inflammation of the bronchial tubes (as in bronchitis), alongside asthma-related symptoms like wheezing, chest tightness and breathlessness.
People may experience frequent coughing with mucus production, especially in the mornings or in polluted environments. Treatment usually includes bronchodilators and anti-inflammatory medications, along with managing environmental triggers.
Similar to asthmatic bronchitis, this condition is marked by asthma symptoms that develop during or after a bout of bronchitis, usually caused by a viral or bacterial infection.
People may experience prolonged coughing, wheezing and fatigue, even after the infection clears. The term is sometimes used interchangeably with asthmatic bronchitis, but it can highlight a triggered flare-up due to an infection, rather than a long-standing chronic issue.
This refers to an asthma attack that becomes severe and does not improve with initial inhaler treatments. It is a medical emergency, and symptoms may include:
Immediate care in an emergency department is essential. Oxygen therapy, nebulisers and sometimes corticosteroids or even mechanical ventilation may be required.
This is a life-threatening, prolonged asthma attack that does not respond to standard treatments like inhalers or nebulisers.
People in this state may experience:
Hospitalisation is necessary, and patients may need aggressive interventions, including intravenous medications and intensive care support. This condition can develop suddenly or build up after poorly managed asthma symptoms.
Asthma management focuses on preventing symptoms and handling flare-ups.
Ask your doctor how to use an inhaler to ensure proper technique. If you are in Singapore, your doctor may recommend an asthma inhaler brand that is readily available locally.

Without proper treatment, asthma may result in:
Asthma is often linked to other conditions like COPD. The GOLD criteria for COPD are used to assess and manage patients with overlapping symptoms.
While asthma may not be completely preventable, you can reduce your risk and avoid flare-ups:
A good care routine helps slow progression and reduces emergency visits.
Asthma is a common chronic condition that affects both children and adults, leading to episodes of breathlessness, chest tightness, wheezing, and coughing. The severity can vary widely, from mild cases that are easily controlled to severe asthma that significantly impacts daily activities.
Environmental triggers such as dust, pollution and respiratory infections are frequent contributors in an urban setting, making early awareness and management important.
Managing asthma in Singapore often begins with a consultation with a general practitioner or respiratory specialist. Patients undergo lung function tests and a detailed review of their symptoms and triggers. Treatment typically involves inhalers, preventive medication and lifestyle modifications to reduce flare-ups.
With ongoing care, patients receive regular check-ups to monitor lung health and adjust treatment when necessary. This step-by-step care ensures that individuals can manage their asthma effectively and maintain a good quality of life.
It is important to seek medical attention for asthma in Singapore if symptoms become more frequent, interfere with sleep or physical activity, or if inhalers are no longer providing relief. Severe warning signs, such as difficulty speaking, persistent wheezing, or a sudden drop in peak flow readings, require immediate medical care. Early intervention helps reduce the risk of complications and ensures that patients receive the right treatment at the right time.
You don’t have to manage asthma alone. A specialist can help assess your symptoms, provide an accurate diagnosis, adjust medication and offer strategies for managing triggers and preventing flare-ups.
