Chronic obstructive pulmonary disease (COPD) is a long-term lung condition that makes breathing harder over time. It develops when the airways become inflamed and the tiny air sacs in the lungs are damaged1. In Singapore, COPD is among the top 10 causes of death2, yet many people who have it may not know3.
Because early signs, such as a lasting cough, phlegm or breathlessness, can develop slowly, they are often brushed off as ageing, being unfit, or asthma1. While existing lung damage cannot be reversed, COPD can be managed. With the right treatment and support, many people can breathe more comfortably, reduce flare-ups and stay active for longer.
What is COPD?
COPD is an umbrella term for a group of long-term lung conditions that block airflow and make breathing difficult. The two most common are:
- chronic bronchitis, where the airways become inflamed and produce excess mucus, and
- emphysema, where the air sacs at the ends of the airways are damaged, reducing how well the lungs take in oxygen.
COPD is progressive, meaning it tends to worsen over time, particularly if exposure to smoking, fumes or other lung irritants continues1. Acting early can slow its progression, ease symptoms and improve day-to-day breathing.
Symptoms of COPD
COPD symptoms usually develop gradually and become more noticeable over time. Common symptoms include:
- A persistent cough that does not go away
- Coughing up phlegm or mucus, especially in the mornings
- Breathlessness, particularly during physical activity
- Wheezing
- Chest tightness
- Frequent chest infections
If you find yourself getting breathless while doing things that did not trouble you before, or you have a cough that has lasted for months, it is worth speaking to a GP rather than assuming it is just age.
Who Is More Likely to Develop COPD?
COPD can affect anyone, but some factors can increase your risk:
- Smoking, which is the leading cause of COPD
- Exposure to second-hand smoke
- Long-term exposure to dust, fumes or chemicals at work
- Long-term exposure to air pollution
- Being over the age of 40
- A rare inherited condition called alpha-1 antitrypsin deficiency
You do not have to be a current smoker to develop COPD — many people who develop it are former smokers, and some have never smoked at all, developing it due to occupational or environmental exposure3. If any of these apply to you and you have ongoing respiratory symptoms, it is worth getting checked.
Talk to a Healthway Medical GPHow COPD is Diagnosed
If you have a long-standing cough, phlegm or breathlessness, your GP will usually start by asking about your symptoms, your smoking history, and any exposure to dust, fumes or pollution. They may also check your breathing and overall health.
The main test used to confirm COPD is spirometry, a simple breathing test where you blow into a machine that measures how much air you can breathe out and how quickly1. Your GP may also arrange a chest X-ray to rule out other causes of your symptoms. Because COPD is often under-diagnosed, getting tested is the most important step if you are at risk3.
Managing COPD
The goals of COPD management are to ease symptoms, reduce flare-ups, slow disease progression and help you stay active. Your GP can help tailor a plan based on your symptoms and overall health and arrange regular reviews to keep it on track.
How COPD is Managed
Depending on your symptoms, your care plan may include:
- Stopping smoking, which is the most effective thing you can do. If you smoke, quitting slows the disease and improves how you feel, no matter how long you have smoked1 2. Your GP can support you with this. Read our guide on how to quit smoking.
- Inhalers, usually bronchodilators that relax and open the airways, and sometimes inhaled steroids to reduce inflammation. These should be used correctly and reviewed regularly2.
- Vaccinations, such as the influenza and pneumococcal vaccines, to lower your risk of chest infections that can trigger flare-ups.
- Pulmonary rehabilitation, a supervised programme of exercise and education that helps you breathe and move more easily, where appropriate.
- Regular reviews to check your symptoms, inhaler technique and overall health.
Used consistently, these steps can help keep symptoms and flare-ups under control and maintain a good quality of life.
What can Trigger a COPD Flare-Up
A flare-up, or exacerbation, is when COPD symptoms suddenly worsen over a few days, often beyond your usual day-to-day breathlessness. Flare-ups are commonly triggered by1:
- Chest infections, including colds and flu
- Air pollution and haze
- Cigarette smoke, including second-hand smoke
You can lower your risk by keeping up with vaccinations, staying indoors and using an air purifier or mask when haze is bad, avoiding smoke, and taking your medication as prescribed. Flare-ups should be taken seriously, as untreated ones can worsen quickly and lead to serious complications1.
When to Seek Urgent Medical Attention
Most COPD symptoms can be managed day to day with your GP, but some flare-ups need prompt care. Seek medical attention urgently if you experience:
- Breathlessness that is severe or getting rapidly worse
- A flare-up that is not improving with your usual treatment
- Blue or grey lips or fingertips
- Confusion, drowsiness or difficulty staying awake
If breathing becomes very difficult or you cannot speak in full sentences, call 995 for an ambulance or go to the nearest emergency department.
COPD Care at Your GP
A GP is a suitable first point of care for COPD, whether you are worried about ongoing symptoms, have just been diagnosed, or are managing the condition long term. As a long-term condition, COPD is well suited to ongoing management in primary care2.
Your GP can support you by:
- Assessing your symptoms and arranging spirometry to confirm whether you have COPD
- Helping you tell COPD apart from asthma or other causes of breathlessness
- Starting and adjusting inhaler treatment, and checking your inhaler technique
- Supporting you with smoking cessation
- Keeping your vaccinations up to date to help prevent flare-ups
- Coordinating care if you also have heart disease, diabetes or other conditions
- Referring you to a respiratory specialist if your symptoms are difficult to control or more detailed assessment is needed
For stable, routine reviews and repeat prescriptions, telemedicine may also be a convenient option. If your breathing symptoms are new, worsening or difficult to control, an in-clinic review is recommended.
Using MediSave for COPD Care
COPD is one of the conditions covered under Singapore's Chronic Disease Management Programme, also known as CDMP. Eligible Singapore Citizens and Permanent Residents may use MediSave to offset eligible outpatient COPD treatment costs at accredited GP clinics, subject to prevailing scheme limits and eligibility criteria.
From 1 February 2024, patients enrolled in Healthier SG with a CDMP condition may use MediSave to fully pay for treatment at their enrolled clinic, up to prevailing withdrawal limits, with no 15% cash co-payment required4.

COPD can't be cured, and existing lung damage can't be reversed — but it's a very manageable condition. With the right treatment and support to stop smoking, most people can ease their symptoms, reduce flare-ups and slow the condition down. The earlier it is picked up, the more can be done.
COPD and asthma can cause similar symptoms, such as breathlessness and wheezing, but they are different conditions. COPD is usually caused by long-term smoking or exposure to lung irritants and tends to develop later in life, with airflow that is largely fixed. Asthma is often linked to allergies, can start in childhood, and tends to vary day to day. Because the two can be hard to tell apart, a GP can assess your symptoms and use a breathing test to work out which you have.
Yes. While smoking is the leading cause, COPD can also result from second-hand smoke, long-term exposure to dust, fumes or chemicals at work, air pollution, or a rare inherited condition. If you have ongoing respiratory symptoms, it is worth getting checked even if you have never smoked.
Yes. Stopping smoking is an effective way to slow COPD, and it helps at any stage, no matter how long you have smoked. It will not undo existing damage, but it slows further decline and improves how you feel. Your GP can help you quit.
In many cases, yes. Keeping up with influenza and pneumococcal vaccinations, taking your medication as prescribed, avoiding smoke and protecting yourself during haze can help reduce the risk of flare-ups. Your GP can help you put a plan in place and advise you on what to do if symptoms worsen.
