Pneumonia: Symptoms, Causes, and Treatment Options
Pneumonia is an infection of the lungs caused by bacteria, viruses, or fungi. It can range from mild to severe and can be life-threatening if not treated properly. The symptoms of pneumonia can vary depending on the severity of the infection, but they may include:
- Fever and chills
- Coughing, which may produce mucus or pus
- Shortness of breath
- Chest pain
- Fatigue
- Loss of appetite
- Confusion (in older adults)
Pneumonia is diagnosed based on the symptoms and a physical examination. A chest X-ray may be done to confirm the diagnosis and to determine the extent of the infection.
Treatment for pneumonia depends on the type of infection and the severity of the symptoms. Antibiotics are used to treat bacterial pneumonia, while antiviral medications are used to treat viral pneumonia. If the pneumonia is severe, hospitalization may be necessary to provide supportive care, such as oxygen therapy and intravenous fluids.
