What is COPD?

Overview

COPD (Chronic Obstructive Pulmonary Disease) is a progressive lung disease that makes breathing difficult. Symptoms include shortness of breath, wheezing, chest tightness, and coughing. COPD is the fourth leading cause of death in the United States, and it affects more than 16 million Americans.

Types of COPD

There are two main types of COPD:

• Emphysema - This type of COPD damages the alveoli, the tiny air sacs in the lungs that allow oxygen to pass into the bloodstream. Emphysema can cause shortness of breath, wheezing, and chest tightness.
• Chronic bronchitis - This type of COPD causes inflammation and narrowing of the bronchi, the tubes that carry air to and from the lungs. Chronic bronchitis can cause coughing, wheezing, and chest tightness.

Causes of COPD

COPD is most commonly caused by smoking. Other risk factors for COPD include:

• Exposure to secondhand smoke
• Exposure to air pollution
• Occupational exposure to dust and chemicals
• A family history of COPD

Symptoms of COPD

The symptoms of COPD can vary depending on the severity of the disease. Common symptoms include:

• Shortness of breath
• Wheezing
• Chest tightness
• Coughing
• Fatigue
• Weight loss
• Swelling in the feet and ankles

Diagnosis of COPD

COPD is diagnosed based on a physical examination, a spirometry test (a test that measures lung function), and a chest X-ray. Your doctor may also order other tests, such as a blood test or a CT scan, to rule out other conditions.

COPD is a serious disease, but it can be managed with treatment. Treatment options for COPD include:

• Medications
• Pulmonary rehabilitation
• Oxygen therapy
• Surgery

COPD is a progressive disease, which means that it will get worse over time. However, with proper treatment, you can manage your symptoms and improve your quality of life.
