In a condition known as hypersensitivity pneumonitis, fibrosis of the lungs can develop following a heightened immune reaction to inhaled organic dusts or occupational chemicals. This condition most often results from inhaling dust contaminated with bacterial, fungal, or animal products. Examples include silo fillers disease and pigeon breeders lung disease.

Getting pneumonia after surgery can be quite serious. According to the CDC, studies have suggested that pneumonia acquired in the hospital can be fatal as often as 33% of the time. So you need to make an effort to protect yourself.
Follow your doctor's instructions about not eating or drinking before surgery. Usually, your doctor will tell you not to eat or drink after midnight the night before surgery. You must follow that advice. If you're going under anesthesia and still have food in...
In some people, in fact in most cases, chronic pulmonary inflammation and fibrosis develop without an identifiable cause. Most of these people have a condition called idiopathic pulmonary fibrosis (IPF) that does not respond to medical therapy, while some of the other types of fibrosis, such as nonspecific interstitial pneumonitis (NSIP), may respond to immune suppressive therapy.
Other names for various types of pulmonary fibrosis that have been used in the past include chronic interstitial pneumonitis, Hamman-Rich Syndrome, usual interstitial pneumonitis (UIP) and diffuse fibrosing alveolitis.
What Are Pulmonary Fibrosis Symptoms?
Symptoms of pulmonary fibrosis include shortness of breath, cough, and diminished exercise tolerance. The severity of symptoms and the worsening of symptoms over time can vary and are at least partially dependent upon the cause of the fibrosis.
How Is Pulmonary Fibrosis Diagnosed?
Pulmonary fibrosis is suggested by a history of progressive shortness of breath with exertion. Sometimes, during examination of the lungs with a stethoscope, the doctor can hear crackling sounds in the chest. The chest X-ray may or may not be abnormal, but a special X-ray test called a high-resolution CAT scan will frequently demonstrate abnormalities. Lung function testing is distinctly abnormal.
The diagnosis can be confirmed by lung biopsy. An open surgical biopsy, meaning that the chest wall must be surgically opened under general anesthesia to remove a portion of lung tissue, may be necessary to obtain enough tissue to make an accurate diagnosis. The removed tissue is examined microscopically by a pathologist to confirm the presence of fibrosis.
