Pneumonia - Symptoms and causes
OVERVIEW
Pneumonia is an infection that causes inflammation of the air sacs in one or both lungs. The air sacs can fill with fluid or pus (purulent material), causing coughing up phlegm or pus, fever, chills, and difficulty breathing. Various organisms, including bacteria, viruses, and fungi, can cause pneumonia. Pneumonia can range in severity from mild to life-threatening. It is most serious in infants and young children, people over age 65, and people with health problems or weakened immune systems.
Symptoms
Signs and symptoms of pneumonia range from mild to severe, depending on factors such as the type of germ causing the infection, your age, and your overall health. Mild signs and symptoms are usually similar to those of a cold or the flu, but they last longer.
Signs and symptoms of pneumonia may include:
- Chest pain when breathing or coughing
- Confusion or changes in mental awareness (in adults age 65 and older)
- Cough that may produce phlegm
- Fatigue
- Fever, sweating, and chills
- A lower-than-normal body temperature (in adults age 65 and older and people with weakened immune systems)
- Nausea, vomiting, or diarrhea
- Difficulty breathing
Newborns and infants may not show any signs of infection. Or they may vomit, have a fever and cough, appear anxious, tired, or lack energy, or have trouble breathing and eating.
When to see a doctor
See your doctor if you have difficulty breathing, chest pain, a persistent fever of 102°F (39°C) or higher, or a persistent cough, especially if you're coughing up pus.
It's especially important for people in these high-risk groups to see their doctor:
Adults over age 65
Children under age 2 who have signs and symptoms
People with an underlying health condition or weakened immune system
People who are receiving chemotherapy or taking medications that suppress the immune system
For some older adults and people with heart failure or chronic lung problems, pneumonia can quickly become life-threatening.
