Pneumonia is often treated successfully with medication, however in some cases, especially in people with compromised immune systems, or in a high-risk category, complications may occur. Complications may include bacterial infections that spread to other parts of the body, potentially causing organ failure. Additional complications may include:
- Lung abscess
- Fluid accumulation in the lungs
- Difficulty breathing
In some cases, hospitalization may be necessary to stabilize breathing through a mechanical ventilator or to drain infected fluid through a chest tube, or through surgery.
