What is lung inflammation?

Lung inflammation means the multiplication of the inflammatory cells (leukocytes, macrophages) and, sometimes, fluid in the lungs.

Symptoms of Lung Inflammation

The most common symptom of lung inflammation is a cough. Other symptoms can include coughing up mucus, shortness of breath, fever, night sweats and fatigue.


Types of Lung Inflammation

Pneumonia is a lung inflammation caused by infection:

Tuberculosis is an infection of the lungs with the Mycobacterium tuberculosis.

Sarcoidosis is an autoimmune disease with an accumulation of the groups of inflammatory cells called granulomas in the lungs and lymph nodes.

Pneumonitis is lung inflammation from causes other than infection, for example, aspiration of vomit or inhalation of toxic gases (chemical pneumonitis) or silica fiber (silicosis), radiation or autoimmune disease.

  • Eosinophilic pneumonitis┬áis caused, for example, by intestinal parasites or drugs. The condition is widely known as eosinophilic pneumonia, which is a technically incorrect term, because no infection is involved.
