BronchitisWhat are the Symptoms and Treatments

Bronchitis is an acute inflammation of the air passages within the lungs. It occurs when the trachea (windpipe) and the large and small bronchi (airways) within the lungs become inflamed because of infection or other causes.

The thin mucous lining of these airways can become irritated and swollen.

The cells that make up this lining may leak fluids in response to the inflammation.

Coughing is a reflex that works to clear secretions from the lungs. Often the discomfort of a severe cough leads you to seek medical treatment.

Both adults and children can get bronchitis. Symptoms are similar for both.

Infants usually get bronchiolitis, which involves the smaller airways and causes symptoms similar to asthma.

July 25, 2007 presentation by Norman Rizk for the Stanford School of Medicine Medcast lecture series.

Pneumonia occurs when a person’s lungs become inflamed and filled with fluid as a result of infection by bacteria, viruses or fungi. Though treatment protocols have significantly advanced since the Great Pandemic of 1918 — when mortality rates were 320 times those of today — pneumonia is still the 6th leading cause of death in the United States. Norman Rizk, MD, professor of medicine, discusses some of the current challenges in diagnosis and treatment, including the issue of drug-resistant bacteria and the prevalence of hospital-acquired pneumonia.
