How Does COPD Affect Your Lungs?
Healthy lungs work like an elastic sponge: with each breath in, they expand and take in air; with each breath out, they contract and release it. In COPD patients, this mechanism is damaged in two main ways: the bronchi thicken and narrow (chronic bronchitis), and the elasticity of lung tissue weakens (emphysema). As a result, air becomes "trapped" in the lungs and is hard to breathe out — causing shortness of breath even with small efforts.
It's important to understand: COPD is different from asthma. While asthma airway narrowing is usually reversible (with the right medications), in COPD the blockage is mostly permanent. Treatment doesn't restore lung function to its former level, but can significantly slow the decline and improve quality of life.
"Quitting smoking is the most critical step. Even if the disease is already diagnosed — someone who quits smoking significantly slows its progression."
— Dr. Israel Israeli, Leading Pulmonologist
Who's at Risk?
Most COPD patients are smokers or former smokers. But there are additional risk factors to be aware of, especially if you have persistent breathing symptoms without a smoking history.
First Warning Signs
Many patients don't know they're sick in the early stages. Symptoms start mildly and are sometimes attributed to "age" or "being out of shape." Early detection is key — the sooner treatment begins, the more we can slow the disease's progression.
In any case of chronic cough (over 3 months), shortness of breath during activities that weren't previously challenging, or increased sputum — it's worth seeing your family doctor for evaluation. A simple lung function test (spirometry) can confirm or rule out the diagnosis within minutes.
