COPD: Early Signs That Are Easy to Dismiss

By Dr. Gabriel Grabowski, specialist in internal medicine and pulmonology

I often see how easily gradual changes in breathing can become part of everyday life. A morning cough may feel normal after years of smoking. Walking more slowly uphill may seem like an inevitable part of getting older. Yet these changes sometimes deserve a closer look.

Chronic obstructive pulmonary disease, or COPD, is a long-term lung condition in which airflow is persistently limited. It usually develops gradually. Recognising possible signs is not about assuming the worst; it is about understanding when a medical assessment may be useful.

A cough that becomes part of the routine

An occasional cough is common and does not automatically suggest COPD. However, a cough that persists, keeps returning, or regularly brings up mucus should not simply be accepted as a “smoker’s cough.”

Some people cough mainly in the morning. Others notice that they need to clear their throat frequently or that cough and mucus linger after a respiratory infection. These symptoms can develop so slowly that it becomes difficult to remember when they started.

In my consultations, I ask about patterns rather than just whether someone has a cough:

• How long has it been present?
• Does it happen most days or only occasionally?
• Is there mucus, and has its amount or appearance changed?
• Does coughing disturb sleep or interfere with activities?

Cough has many possible causes, including asthma, reflux, nasal problems and certain medicines. The purpose of an examination is to explore these possibilities, not to label every persistent cough as COPD.

Breathlessness is not always just age

Getting out of breath during strenuous activity can be normal. What matters is a change from your usual level: needing to pause on stairs you previously climbed comfortably, struggling to keep pace on a familiar walk, or avoiding activities because breathing feels harder.

People sometimes adapt without noticing. They take the lift, walk more slowly, or let someone else carry the shopping. These adjustments can hide a gradual loss of exercise tolerance.

Other symptoms worth mentioning include:

• Wheezing or a whistling sound when breathing
• Chest tightness
• Respiratory infections that seem to take longer to settle
• Unusual tiredness during ordinary tasks

None of these symptoms is specific to COPD. Heart conditions, anaemia, reduced fitness and other lung disorders can also cause breathlessness. I therefore consider the whole picture rather than attributing a symptom to age or smoking alone.

Sudden or severe breathlessness, chest pain, coughing up blood, or new confusion requires urgent medical assessment. These are not symptoms to wait with until a routine appointment.

Why your smoking history matters

Smoking is a major risk factor for COPD, but not everyone who smokes develops it, and COPD can also occur in people who have never smoked. Long-term exposure to dust, fumes or indoor smoke may contribute. Less commonly, inherited factors play a role.

I ask about current and previous smoking without judgement. The number of years smoked, the usual amount, and when someone stopped all help put symptoms into context. Doctors sometimes summarise this exposure in “pack-years”: smoking one pack of 20 cigarettes daily for 20 years equals 20 pack-years.

Stopping smoking is important at any age. It can slow the loss of lung function associated with COPD, although it does not reverse established lung damage. If stopping is difficult, a clinician can discuss suitable support and medication options. Previous attempts are useful information, not a reason for criticism.

Spirometry: checking how air moves

Symptoms and smoking history can raise suspicion, but they cannot confirm COPD on their own. Spirometry is a breathing test that measures how much air you breathe out and how quickly you can exhale it.

During the test, you take a deep breath and blow forcefully into a mouthpiece. Several attempts are usually needed for reliable measurements. Testing is commonly repeated after an inhaled medicine that opens the airways, to check whether airflow limitation persists.

I interpret the results alongside symptoms, exposure history and the clinical examination. Depending on the findings, other investigations may be appropriate. Spirometry also helps distinguish between possible causes, although no single result explains every breathing problem.

If you have a persistent cough, increasing breathlessness or a relevant smoking history with symptoms, arrange an assessment. Beforehand, note when symptoms occur, how activity has changed, your smoking history and your current medicines. This can make the discussion more focused.

Consultations are possible at the three practices in Nürnberg, La Cala de Mijas and Estepona. The appropriate next steps depend on an individual medical assessment.
