Question

What are the causes of pleural effusion

Answer 1

This type is caused by fluid leaking into the pleural space as a result of either a low blood protein count or increased pressure in the blood vessels. Its most common cause is congestive heart failure.

Answer 2

A wide range of things can cause a pleural effusion. Some of the more common ones are:

Leaking from other organs. This usually happens if you have congestive heart failure, when  your heart doesn't pump blood to your body properly. But it can also come from liver or kidney disease, when fluid builds up in your body and leaks into the pleural space.

Cancer. Usually lung cancer is the problem, but other cancers that have spread to the lung or pleura can cause it, too.
