Overview

Pleurisy (“PLUR-uh-see”) happens when the lining (tissue layer) around your lungs or the lining on the inside wall of your chest swells up. This makes the two layers rub against each other, causing sharp pains. Pleurisy is also called pleuritis.

Your lungs and the inside of your chest are each lined with a thin layer called pleura. The space between them (pleural space) is filled with fluid that allows them to slide smoothly along each other when you breathe, like oil in a machine. When one or both layers become swollen (inflamed), they rub painfully against each other instead.

How do I know if I have pleurisy?

Pleurisy causes chest pain that’s sharp and stabbing. There are lots of different conditions that can cause chest pain, and many of them need immediate medical attention. The only way to know for sure if you have pleurisy is to get checked by your healthcare provider.

How do you get pleurisy?

You can get pleurisy when inflammation from your lungs — caused by a virus, bacteria or other illness — moves into your pleurae, causing them to swell up and rub against each other. This can also happen if there’s a blockage (like a tumor) or damage to your lung.

Who does pleurisy affect?

Anyone can get pleurisy, but you’re at a higher risk if you:

  • Are over 65.
  • Have a condition that causes inflammation in your body (like an autoimmune disease).
  • Take medications that cause inflammation in your body.
  • Have tumors or scarring in your lungs.

How serious is pleurisy?

Pleurisy can be mild or very serious. It depends on what’s causing it and whether you have additional complications.

Complications

Blood clots are a dangerous complication of atrial fibrillation (AFib). Blood clots can lead to stroke.
The risk of stroke from AFib increases as you grow older. Other health conditions also may increase the risk of a stroke due to AFib. These conditions include:
  • High blood pressure.
  • Diabetes.
  • Heart failure.
  • Some types of heart valve disease.
Blood thinners are commonly prescribed to prevent blood clots and strokes in people with atrial fibrillation.

Prevention

Healthy lifestyle choices can reduce the risk of heart disease and may prevent atrial fibrillation (AFib). Here are some basic heart-healthy tips:
  • Control high blood pressure, high cholesterol and diabetes.
  • Don't smoke or use tobacco.
  • Eat a diet that's low in salt and saturated fat.
  • Exercise at least 30 minutes a day on most days of the week unless your health care team says not to.
  • Get good sleep. Adults should aim for 7 to 9 hours daily.
  • Maintain a healthy weight.
  • Reduce and manage stress.
