The disease caused by inhalation of asbestos dust is:
Open in App
Solution
The correct option is A Emphysema
Asbestosis is a chronic lung disease characterized by a scarring of lung tissues, which leads to long-term breathing complications. Interstitial lung disease from asbestos exposure can take 10 to 30 years to appear from the time of the initial exposure. The inflammation causes thickening and scarring of the interstitium, the air sacs (alveoli) also become thicker and they begin to lose their elasticity as in emphysema. Gradually, the air sacs lose more and more of their capability to put oxygen into the blood and remove carbon dioxide. Therefore, the correct answer is option A.
