COPD Ignored by Doctors and Patients
New Approach Needed in Detecting and Treating Nation's No. 4 Killer: COPD
Nov. 6, 2003 (New York) -- The term COPD may not strike fear in the hearts of most Americans like SARS or cancer, but that may soon change if the nation's lung specialists have their way.
"COPD is the fourth leading cause of death in the U.S., yet it is a disease that very few people know anything about, and it is increasing alarmingly in the U.S. and throughout the world," says A. Sonia Buist, MD, professor of medicine at Oregon Health & Science University in Portland.
At a time when other major causes of death such as heart disease and cancer are declining, the death rate for COPD, or chronic obstructive pulmonary disease, has skyrocketed by 163% in the last 30 years, and Buist says a rapid rise in COPD deaths among women is fueling that increase.
In an effort to reverse those disturbing trends, Buist and other COPD experts announced Thursday a new national campaign to increase awareness and detection of COPD among physicians and their patients at a briefing in New York City, sponsored by the American Medical Association.
What Is COPD?
COPD is a term that was introduced in the 1960's. It's an umbrella term for diseases of the lung, such as emphysema and chronic bronchitis, which result in a progressive and abnormal decline in lung function.
Most of the estimated 16 million people in the U.S. with COPD suffer from a combination of these diseases that cause inflammation and destruction within the lungs and make it difficult to breathe.
Smoking causes up to 90% of COPD cases in the U.S., but air pollution is also major contributor it in developing countries.
Researchers say everyone begins to experience a natural decline in the amount of air their lungs can hold (lung capacity) after about age 35. Nonsmokers lose about an average of two tablespoons of lung capacity per year. But smokers lose three to four times of their lung capacity annually, which dramatically increases their risk of death and disability caused by COPD.
Experts say confusion about the variety of terms used to describe the conditions involved in COPD has made it difficult for the public as well as the medical community to understand this very common disease.
