COPD, or Chronic Obstructive Pulmonary Disease, describes lung and airway diseases that restrict breathing.
In COPD there is irreversible damage to the lungs and airway that makes it hard to breathe.
Some of the changes in your lungs and airways due to COPD can include:
- Loss of elasticity in the airways and air sacs of your lungs
- Inflammation and/or scarring (fibrosis) and narrowing of the airways
- Thick mucus in your airways
- Damage to the walls between the air sacs in your lungs
What are the types of COPD?
Two types of COPD are emphysema and chronic bronchitis. People with COPD often have features and symptoms of both.
Emphysema
Chronic bronchitis
Understanding COPD
Take a virtual tour of the lungs to understand how COPD impacts lung function and overall respiratory health.
What are the symptoms of COPD?
What are COPD flare-ups?
People with COPD often get flare-ups, also known as exacerbations, which are worsening symptoms. These can include severe difficulty breathing, thicker mucus, wheezing, and cough. Severe exacerbations can require hospitalization.
As COPD gets progressively worse over time, flare-ups can become more severe and happen more often. Progression usually occurs over the course of years. However, for some patients COPD can worsen more quickly.
What causes COPD?
The most common cause of COPD is damage to the lungs from smoking. Other causes may include:
- A genetic disorder called alpha-1 antitrypsin deficiency that can cause lung damage
- Secondhand smoke
- Environmental factors such as toxins in the air
- Occupational factors such as dust and fumes at your job
How is COPD managed and treated?
There is no cure for COPD. Treatment focuses on improving symptoms and reducing the risk of flare-ups. You will work with your health care team to come up with a treatment plan that best meets your needs.
