COPD
(Chronic obstructive pulmonary disease)
is a progressive disease that keeps your lungs from functioning
normally. It is characterized by a gradual loss of lung function.
The airways in your lungs are blocked, and breathing takes more
effort.
COPD includes chronic bronchitis, emphysema, and chronic asthma,
or some combination of these conditions. It is usually the result
of smoking, exposure to second-hand smoke and exposure to occupational
dusts.
ASTHMA
is a chronic lung disease in which the
linings of the airways become inflamed and swollen, and muscle
spasms restrict the flow of air
to the lungs. Asthma symptoms may include difficulty breathing,
a tight feeling in the chest, coughing, and wheezing. There is
no known cure for COPD or Asthma. Treatment is usually supportive
and designed to relieve symptoms and improve quality of life
through appropriate use of drugs, medical supplies and disease
management techniques. |
