What is a typical symptom of pneumonia?

Increased fatigue is a typical symptom of pneumonia and relates closely to how the body responds to infection. When someone has pneumonia, the lungs become inflamed and filled with fluid, which can result in a decline in oxygen exchange. This decreased oxygenation can lead to fatigue, as the body has to exert more energy to perform normal activities and fight off the infection. Additionally, the body's immune response to the pneumonia can cause an overall sensation of tiredness and a feeling of malaise, increasing fatigue levels.

While headaches, dry throat, and stuffy nose may be symptoms associated with other respiratory conditions or infections, they are not primary indicators of pneumonia. Understanding the key symptoms of pneumonia, like increased fatigue, can help in recognizing the condition and seeking timely medical attention.
