Hello and welcome to HCM forum.
Asbestosis,a condition that affects the lungs ,usually occurs after high intensity and/or long-term exposure to asbestos (particularly in those individuals working on the production or end-use of products containing asbestos) and is therefore regarded as an
occupational lung disease .
The primary symptom of asbestosis is generally the slow onset of breathlessness , especially on exertion.It may manifest from years to decades after the exposure .
In my opinion your condition may not be beacuse of asbestosis ,rather your
Tracheobronchomalacia (TBM) and
bronchiectasis could be the main culprits.
An Xray can confirm the finding of fibrosis caused by asbestosis .
You may need
Oxygen therapy if your breathing does not improve with Nebulised Albeuterol and
Glutathione .Some people might need surgical correction of TBM which a clinical examination and Pulmonary function tests should help in assessing .
There is not much chance of reversing the changes in your lungs ,it can mostly be managed .
I would like you to go through this link which is greatly helpful to most patients .
