Pulmonary fibrosis is a group of disorders that initiates general fibrosis and damage to the lungs. People who are experiencing this illness have shortness of breath, dry cough, exhaustion, and weakness. It is also characterized by the scarring of lung tissue, as it becomes less malleable and is incapable of working as good as the healthy tissue. Unfortunately, the scarring of lung tissue is irreversible, and people never fully recuperate from pulmonary fibrosis. Chronic obstructive pulmonary disease is a progressive lung disorder that has no known cure.
COPD can occur in families. Symptoms of COPD involve but are not limited to shortness of breath, wheezing, frequent lung infections, and dry or productive cough. In advanced stages, the patient can become confused, cyanotic, and experience edema in the ankles, feet, and legs. Although COPD can be genetic, it can also be caused by smoking and occupational exposures.
