What's the difference between COPD and other lung conditions?
COPD is a specific chronic lung disease, not a catch-all term for all lung conditions. While COPD shares some symptoms with other lung diseases like asthma, they are distinct conditions.
Key differences between COPD and asthma:
- COPD typically develops after age 50 and is usually caused by smoking or long-term lung damage
- Asthma often starts in childhood and is triggered by allergies
- With asthma, breathing tests show changes that are mostly reversible with medication
- With COPD, lung damage is permanent and doesn't respond as well to treatment
- COPD generally gets worse over time, while asthma can be well-controlled
Some people have both conditions, which is called asthma-COPD overlap.
Types within COPD:
COPD itself is an umbrella term for lung conditions that block airflow. The two main types are:
- Emphysema: damages the tiny air sacs (alveoli) in your lungs
- Chronic bronchitis: causes inflammation and mucus buildup in your airways
Most people with COPD have both emphysema and chronic bronchitis together.
Understanding which type of COPD you have helps your care team create the best treatment plan for your specific symptoms.
