Asthma - Reversible Lung Disease and Cosmetic Surgery


Please tweet and retweet


Obstruction to airflow in the lungs can be due to
  1. fixed or irreversible lung disease (COPD)
  2. reversible (responsive to medications) obstruction due to heart failure
  3. reversible (responsive to medications) obstruction due to asthma
The obstruction can be due to just one of the factors or any combination of 2 or more factors.

In asthma the walls of the breathing tubes into the lungs swell (become inflamed), muscles surrounding the tubes contract squeezing the tubes and then increased mucus secretions inside those tubes plugs them. This results in obstruction to airflow with audible wheezing and a tight feeling in the chest as the individual tries to get the air through narrowed plugged tubes. Attacks can be mild resolving quickly with medication or severe and life threatening.
