COPD (Chronic obstructive Pulmonary disease) is a major cause of disability, and it's the third leading cause of death in the United States and in a country like India, it's emerging as a highly deadly disease. Currently, millions of people are diagnosed with COPD. Many more people may have the disease and not even knowing it. COPD develops slowly. Symptoms often worsen over time and can limit ones’s ability to do routine activities.

Severe COPD may prevent you from doing even basic activities like walking, cooking, or taking care of yourself. Most of the time, COPD is diagnosed in middle-aged or older adults. The disease isn't passed from person to person; you can't catch it from someone else. Treatments and lifestyle changes can help you feel better, stay more active, and slow the progress of the disease.
