A 43-year-old member asked:

what is the simplest definition of chronic obstructive pulmonary disease (copd)?

Dr. Sue Ferranti
Internal Medicine 29 years experience
COPD...: COPD is a disease characterized by the presence of chronic, irreversible airway obstruction as measured by pulmonary function testing. The disease is incurable but there are treatments available so see your doctor for diagnosis and treatment. The most important treatment is smoking cessation since smoking is the main etiology of this disease.

What is the outlook for a child diagnosed with pulmonary atresia (pa)?

Depends: Depends on whether there is also an intact or open ventricular septum (vsd) and how quickly and effectively the pulmonary valve can be opened after birth, if necessary. There's no good "one answer" to this question without a lot more information about the specific case.

Dr. Aaron Milstone

Definately: Smoking is the number one risk factor for the development of emphysema. Other risks include family history, a genetic predisposition (such as Alpha one antitrypsin deficiency) and occupational exposure (usually related to dusts). If you have no desire to develop emphysema do not smoke.

Does cold weather worsen emphysema symptoms?

Dr. Aaron Milstone
Pulmonology 27 years experience
Not necessarily: Some patients with emphysema do better in colder air/cooler temperatures and find extreme heat more difficult. Each patient is an individual and there are no broad recommendations from any organization to avoid cold/heat. It really depends on how you as an individual feel in extremes of temperature.
