Hi there.

COPD is when air flow into and out of the lungs is obstructed for one reason or the other.

The following are causes;
chronic bronchitis
chronic obstructive airways disease
chronic airflow limitation
some cases of chronic asthma

Clinical features of COPD include:
productive cough with wheeze and breathlessness
frequent infective exacerbations with purulent sputum
symptoms are worsened by cold, foggy weather or atmospheric pollution in advanced disease breathlessness may occur on minimal exercise, e.g. dressing
weight loss
poor chest expansion.

Asbestosis is the fibrosis which happens in the lung tissue due to exposure to asbestos. This causes restriction to the exof the lung due to reduced elasticity of the tissue and has nothing to do with obstruction of the airways. Asbestosis may then be followed by a cancer called mesothelioma.

I hope you found this information helpful and if that is the case please click accept. (positive feedback and bonuses will be most welcome.)

Thank you.

Hi again

An Xray can not distinguish the 2. A Chest CT Scan can because the fibrosis caused by asbestosis may show up on it.
