WHAT IS COPD?
Chronic obstructive pulmonary disease (COPD) is a chronic lung disease that includes chronic bronchitis, emphysema, or both. COPD affects the lungs and causes reduced airflow, which makes it hard to breathe. It’s also:
- Progressive (it gets worse over time)
- Different for everyone
- Manageable with treatment
What are the common types of COPD?
COPD can include emphysema and chronic bronchitis. Click on each below to see how they're different:
Emphysema develops over time and involves the gradual damage of lung tissue, specifically the tiny air sacs called the alveoli.
This damage decreases lung surface area and significantly reduces your ability to release the normal amount of air from the lungs resulting in:
- oxygen being prevented from moving through the bloodstream
- difficulty breathing
Bronchitis is when the airways in your lungs, your bronchi, become inflamed. This can lead to severe coughing spells causing:
- excess mucus production
- chest pain
- shortness of breath
Bronchitis is considered chronic (or long term) if you cough and produce excess mucus most days for at least 3 months per year for 2 consecutive years.
Can COPD symptoms get worse over time?
COPD is a progressive condition and symptoms can get worse over time. That’s why it’s important to talk to your healthcare provider if you notice a change in any of the symptoms listed above—and to make sure you’re on a treatment that's right for you.
A COPD flare-up (or exacerbation) occurs when your symptoms are severe for several days or weeks (not just when you need your rescue inhaler for sudden symptoms).
Everyone experiences flare-ups differently. Keep in mind that each time you have a flare-up, it may cause damage to your lungs that can be permanent.
Smoking (firsthand and secondhand)
Chemical fumes at work and at home
Outdoor air pollution
Indoor air quality
There are varying stages of COPD, such as: mild, moderate, severe, or very severe. To find out what stage you’re experiencing, your doctor will examine you; consider your medical history, including symptoms and previous flare-ups; and give you a breathing test (spirometry). The breathing test will tell the doctor if your airflow is limited and where you fall in the GOLD* classification—a scale that measures COPD severity. There are 4 grades or stages in the GOLD classification, with 4 being the most severe.
