COPD Symptoms: From Early Signs to the Advanced Stage

Prof. Dr. Yalçın Karakoca · Last updated: 25 September 2026

SHORT ANSWER

The most common symptom of COPD is shortness of breath that gets worse with exertion. A cough that lasts for weeks and phlegm, especially in the mornings, are also common. Wheezing and tiring quickly also occur. The early symptoms are often put down to ageing or a lack of fitness. This is why the diagnosis is delayed. As the disease progresses, shortness of breath can also occur at rest. Frequent infections, low oxygen levels and weight loss can also occur. Anyone who has smoked and has these symptoms should have a breathing test (spirometry).

Early symptoms (often overlooked)

  • Getting out of breath on stairs or hills more quickly than before
  • A cough with phlegm in the mornings, known as “smoker’s cough”
  • Bronchitis that lasts a long time every winter
  • Slowing down when walking, falling behind people of your age
  • Wheezing, chest tightness

Getting a diagnosis at this point is important. Stopping smoking and starting treatment markedly slow the loss of lung function.

Symptoms in the moderate and advanced stages

SymptomCause
Needing to stop when walking on level ground, shortness of breath when getting dressedNarrowing of the airways and air building up in the lungs
Shortness of breath at restAdvanced narrowing, air build-up and low oxygen levels
Frequent flare-ups (two or more a year) or hospital admission because of a flare-upInfections, polluted air; inflammation in the airways
Lips and fingertips turning blueA drop in the oxygen level in the blood
Morning headache, daytime sleepinessA rise in carbon dioxide in the blood
Loss of weight and muscleMore energy spent on breathing, inflammation in the body
Swelling of the anklesStrain on the right side of the heart
Depression, anxietyThe burden of a long-term illness

The type of symptoms guides treatment

In chronic bronchitis-type COPD, cough and phlegm predominate. In these patients, techniques for clearing phlegm are important. If symptoms persist despite medicines and these techniques, balloon treatment may be considered. In emphysema-type COPD, by contrast, shortness of breath and air building up in the lungs predominate. In these patients, options aimed at reducing lung volume, such as a lung valve, are considered.

How do COPD symptoms change with the stages?

COPD symptoms differ from one stage to the next. At the beginning, shortness of breath is usually noticed when climbing stairs or walking fast. As the disease progresses, everyday tasks also become harder. In the advanced stages there may be breathlessness even at rest, and the cough and phlegm become more marked.

The stages are assessed according to the GOLD classification, and symptoms do not follow the same course in every patient. Which stage your complaints correspond to, and how your treatment will be arranged, depends on your doctor’s assessment. You can read more on the COPD stages page.

The assessment usually looks at:

  • How much shortness of breath affects daily life
  • How the cough and phlegm are changing
  • Frequent chest infections
  • Tiredness and weight changes

How is COPD diagnosed?

Diagnosis begins with an assessment of your complaints and risk factors. Your doctor first asks about shortness of breath, cough and phlegm, and about your smoking history. A breathing test (spirometry) is then done; this is the basic test that shows narrowing of the airways.

  • Chest X-ray: requested to assess the general appearance of the lungs and to rule out other conditions.
  • CT scan: used when needed to see structural changes such as emphysema in more detail.
  • Blood gas test: taken to assess your oxygen level and how well you are breathing.

Your doctor decides which tests are needed and interprets the results. For the options once a diagnosis is made, see the COPD treatment page.

What causes COPD, and who gets it?

COPD is a chronic disease that develops when the lungs are exposed to harmful substances for a long time. The most common cause is cigarette smoke and other products of combustion; see smoking and COPD for details. Dust, chemical fumes and particles in the workplace also raise the risk. Air pollution in cities, especially fine particles, can contribute to the disease. In rare cases, a family predisposition also plays a part.

If you have one or more of the following, it is worth talking to your doctor about assessing your lung function:

  • Smoking, or exposure to cigarette smoke
  • Dust and chemicals in the workplace
  • Living in an area with heavy air pollution
  • A family history of COPD

Emergency symptoms — 112

Call 112 immediately in these situations:

  • Shortness of breath that stops you from talking
  • Turning blue or becoming confused
  • Chest pain
  • Shortness of breath that gets worse quickly, with a fever
  • Your oxygen reading dropping well below your usual level

When should you see a doctor if you have COPD symptoms?

When symptoms last a long time, the cause should always be investigated. A cough that does not go away for weeks, phlegm that comes up especially in the mornings, and shortness of breath that increases with effort are among these symptoms. In people who have smoked, these complaints should not be put down to a cold or to ageing.

It is appropriate to see a chest diseases specialist if:

  • The cough and phlegm do not ease for weeks
  • Shortness of breath has started to make daily tasks harder
  • Wheezing, tiring quickly or chest tightness come with it
  • These complaints keep coming back in a person with a smoking history

Talk to your doctor about having a breathing test and starting treatment. You may also find our pages on shortness of breath, advanced-stage COPD and chronic bronchitis helpful.

PRELIMINARY ASSESSMENT

Is it suitable for you?

Book an appointment and bring your breathing test and chest CT scan reports. We decide together at the consultation. If you are coming from outside Istanbul, an online preliminary consultation can be held first.

Please bring: your breathing test, your chest CT scan report and images (CD/USB), your list of medicines and, if you have one, your blood gas test result.

HAVE A QUESTION?

Frequently asked questions

The questions our patients and their relatives ask most often, with answers. We discuss questions about your own situation together at the consultation.

They usually develop slowly over the years. During a flare-up, however, they can get worse within a few days.

There may be shortness of breath even at rest and a constant need for oxygen. Frequent hospital admissions, weight loss and swelling in the feet may also occur. Details: End-stage COPD.

Yes.

Some changes may be visible, but a normal X-ray does not rule out COPD. A breathing test is needed for the diagnosis.

Thick, yellow-green phlegm may be a sign of an infection or a flare-up. If there is blood in your phlegm, be sure to see a doctor.

APPOINTMENT

Book an appointment for a preliminary assessment

To find out whether you are suitable, book a preliminary assessment appointment. Bring your breathing test, chest CT scan report and list of medicines with you.
