COPD

Chronic obstructive pulmonary disease (COPD) is a group of lung diseases, including chronic bronchitis and emphysema, that blocks airflow to your lungs, making breathing difficult. COPD typically causes coughing, wheezing, shortness of breath, and chest tightness, and your lungs might also bring up more mucus while coughing.

COPD is a progressive disease — meaning that no cure is available and it worsens over time — but treatment can help manage symptoms and improve your quality of life. Lifestyle changes like quitting smoking and taking medications as prescribed can also help slow the progression of COPD.

Common Questions & Answers

What is the life expectancy of someone with COPD?

Life expectancy varies based on the severity of COPD, overall health, and whether the person continues to smoke. With treatment, many people live for years with COPD. Discuss ways to avoid flare-ups with your doctor.

The Social Security Administration recognizes severe COPD as a disabling condition if it limits your ability to work or perform daily activities. However, a diagnosis alone won’t qualify you, and medical evidence of impairment is necessary to claim benefits.

Doctors classify COPD into four stages based on lung function: mild (stage 1), moderate (stage 2), severe (stage 3), and very severe (stage 4). The results of a forced expiratory volume (FEV1) test define which stage you have.

As a progressive disease, COPD is irreversible and will continue to get worse over time. However, you can help slow its progression and reduce the risk of related diseases like lung cancer with treatment, medication, and lifestyle changes like smoking cessation.

End-stage COPD is the most severe stage and leads to extremely limited lung function. You may experience severe shortness of breath — even at rest — and need supplemental oxygen to support breathing.
