Chronic obstructive pulmonary disease (COPD) include a group of diseases that cause progressive lung damage. They include chronic bronchitis, asthma and emphysema.
Patients with emphysema have shortness of breath, chronic mild cough and wheeze.
Smoking is the main cause. The disease progress gradually and usually evident clinically by the age of 50.
The disease is treated mainly by smoking cessation in addition to other supportive measures like bronchiodilators mucolytics and steroids.
Oral steroids showed success to treat outpatients with acute exacerbation; after stabilization gradually withdrawal should be done to avoid adverse effects. Some doctors recommend to keep steroid responder on long-term inhaled steroids.
Small Isolated bullae with normal lung that do not interfere with lung functions are treated by conservative measures. Giant bullae in otherwise normal lung affecting lung function may benefit from surgical excision of the bullae.
