Why does lungs fill up with fluid when having pancreatitis?

This article explains a huge question I've had for a long time. My teenage daughter unfortunately is having pancreas problems for the first time. I have had it on and off for years myself. And, still didn't know the answer to this problem, we both have pancreas issues and asthma. It's hard trying to explain to doctors and ER staff what your symptoms are, when all you can say is that you have this crazy pain that's above your stomach that seems to reach right through to your back, oh and you seem to not be able to breathe either.

Dear, Anon.

Thank you for your post.

Your pancreas is a long, teardrop-shaped organ located deep in your upper abdomen, just beneath your diaphragm and lungs. Its broader end is sandwiched between your stomach and backbone, and its “tail” stretches toward your left kidney. Acute pancreatitis is a sudden swelling and inflammation of your pancreas. Pancreatic inflammation can spread to nearby organs and may even involve organs in other areas of your body. One potential complication of acute pancreatitis is a pleural effusion, a collection of fluid at the bases of your lungs.
