Even with treatment, some people with pneumonia, especially those in high-risk groups may experience complications, including:

  • Bacteria that enter the bloodstream (bacteremia) from the lungs can spread the infection to other organs, and tend to cause organ failure.
  • If the pneumonia is severe or the person has chronic underlying lung diseases, one can have trouble breathing in the enough amount of oxygen.
  • Pneumonia can also cause fluid to build up in the thin space between layers of tissue that line the lungs and chest cavity (pleura).
