Pneumonitis

Pneumonitis

Pneumonitis (pronounced: new-mo-ni-tis) is a general term that refers to inflammation of lung tissue.

Etymology

The term "Pneumonitis" is derived from the Greek words "pneumon" which means "lung" and "-itis" which is used in medicine to denote inflammation.

Definition

Pneumonitis refers to a set of conditions that involve inflammation and swelling in the lungs. This inflammation can be caused by various factors, including allergens, radiation therapy, and certain drugs. It is important to note that pneumonitis is different from pneumonia, which is typically caused by an infection.

Symptoms

Symptoms of pneumonitis may include shortness of breath, cough, and fatigue. In severe cases, it can lead to pulmonary fibrosis, a condition that results in scarring of the lungs.

Causes

Pneumonitis can be caused by a variety of factors, including:

• Exposure to certain types of allergens or environmental toxins
• Certain types of chemotherapy or radiation therapy
• Some types of autoimmune diseases
• Certain medications

Treatment

Treatment for pneumonitis typically involves identifying and avoiding the cause of the inflammation, if possible. Medications, such as corticosteroids, may also be used to reduce inflammation. In severe cases, oxygen therapy or a lung transplant may be necessary.
