Pneumonia Symptoms and Signs
Possible Complications of PneumoniaPeople who have pneumonia often can be treated successfully and not have complications. But some people, especially those in high-risk groups, may have complications such as:
- Pleural effusion. Pneumonia may cause fluid to build up in the pleural space, which is the space between the lungs and chest wall. The disease can cause the fluid to become infected -- a condition called emphysema.
- Bacteremia. This serious complication occurs when the infection moves into the bloodstream. From there, it can quickly spread to other organs, including the brain.
- Lung abscess. An abscess occurs when pus forms in a cavity in the lung.
- Loss of life. Most people do recover from pneumonia. However, loss of life happens in up to 3 percent of pneumonia cases.
