Asthma is a chronic lung disease which narrows and inflames your airways. If you are having any cough, chest tightness, difficulty breathing during or after exercise, you may have asthma.  While mostly controllable, asthma does have the potential to complicate other health conditions, reduce quality of life, and even be fatal when left untreated.

Lung cancer is caused by a growth of abnormal cells in the lungs. These groups of cells are known as a tumor. As the tumor grows, the abnormal cells destroy the healthy lung tissue around them. This will impair the normal function of the lungs.

Pulmonary fibrosis is when your lungs are damaged or scarred. The scarred lung tissue cannot be repaired and it causes a tissue buildup. This  buildup leads to the lungs having to work harder than normal.

Pulmonary hypertension is a blood pressure that is high in the blood vessels that go to the lungs. It can eventually cause damage to the right side of your heart. The walls of the vessels become thick, allowing very little blood to flow through.
