What are Lung diseases that obstruct the flow of blood through lungs most likely to cause?

Lung diseases that obstruct the flow of blood through the lungs are most likely to cause pulmonary hypertension, which is a condition characterised by abnormally high blood pressure in the arteries leading to the lungs. This can lead to a number of symptoms, including chest pain, shortness of breath, fatigue, and dizziness. Pulmonary hypertension can also cause damage to the heart and lungs, and can eventually lead to death.

Some of the lung diseases that can cause pulmonary hypertension include:

- Emphysema: This is a condition in which the air sacs in the lungs are damaged, leading to difficulty breathing.

- Chronic bronchitis: This is a condition in which the airways in the lungs become inflamed and narrowed, making it difficult to breathe.

- Pulmonary fibrosis: This is a condition in which scar tissue forms in the lungs, making it difficult to breathe.

- Asthma: This is a condition in which the airways in the lungs become inflamed and narrow, making it difficult to breathe.

These are just some of the lung diseases that can cause pulmonary hypertension. If you have any of these conditions, it is important to talk to your doctor about the risk of developing pulmonary hypertension.
