Diagnosis of Pneumonia


To diagnose pneumonia, your doctor will take a medical history and conduct a physical exam. They may also order tests, such as a chest X-ray, blood tests, and a sputum culture.

Treatment of Pneumonia


The treatment of pneumonia depends on the type and severity of the infection. Mild cases may be treated with rest, over-the-counter medications, and increased fluid intake. More severe cases may require antibiotics, antiviral medications, or hospitalization.

Complications of Pneumonia


In some cases, pneumonia can lead to serious complications, such as:

Prevention of Pneumonia


Pneumonia can be prevented by getting vaccinated, washing your hands regularly, avoiding contact with people who are sick, and avoiding smoking or exposure to secondhand smoke.
