Pneumonia: Key Causes and Symptoms to Recognize
Pneumonia is a lung infection caused by bacteria, viruses, fungi, or inhaling foreign substances. Common causes include respiratory infections, such as the flu, or a weakened immune system. Symptoms often include cough, fever, shortness of breath, and chest pain. Fatigue, confusion, and difficulty breathing are also signs to watch for.
If left untreated, pneumonia can be life-threatening, especially in the very young, elderly, or those with pre-existing health conditions. Early diagnosis and treatment are essential for recovery, so don't ignore these warning signs. Seek medical help if symptoms worsen or you experience difficulty breathing.
