well i am google looking for this info for you and so far i have found this. Inflammation of lung tissue.

HERE IS SOME INFO I FOUND ON MAYO CLINIC.COM I LOVE THIS SITE.



Pneumonitis (noo-moe-NIE-tis) is a general term that refers to inflammation of lung tissue. Although pneumonia is technically a type of pneumonitis because the infection causes inflammation, most doctors are referring to other causes of lung inflammation when they use the term "pneumonitis."

Factors that can cause pneumonitis include:

Occupational exposure to airborne particles, such as asbestos or silica
Some drugs, particularly chemotherapy drugs
Radiation therapy to the chest
Exposure to poultry, pigeons or pet birds
Many types of mold
Difficulty breathing — often accompanied by a cough — is the most common symptom of pneumonitis. But having these problems doesn't necessarily mean that you have pneumonitis. Specialized tests are necessary to make a diagnosis.

  Bronchioles and alveoli  
Pneumonitis occurs when some irritating substance causes the tiny air sacs (alveoli) in your lungs to become inflamed. This inflammation can hamper the exchange of oxygen in the air sacs.

A variety of irritants, ranging from airborne molds to chemotherapy drugs, have been linked to pneumonitis. But for most people, the specific substance causing the inflammation is never identified.

Drugs
A variety of drugs used to treat other conditions can cause pneumonitis.

Antibiotics. Nitrofurantoin, amphotericin B, minocycline, sulfasalazine and sulfadiazine have been linked to pneumonitis. Chemotherapy drugs. The types of cancer-fighting drugs most likely to cause pneumonitis include bleomycin, methotrexate, carmustine, busulfan and cyclophosphamide. Heart drugs. Medicines to keep your heartbeat regular, such as amiodarone, may cause pneumonitis in some people. Fungi and other allergens
Specific varieties of pneumonitis have received nicknames such as "farmer's lung" or "hot tub lung." The lung irritants involved include:

Mold
Feathers or bird excrement
Radiation treatments
Some people who undergo radiation therapy to the chest for cancer may develop pneumonitis. This is most likely to occur in people being treated for:

Lung cancer
Breast cancer
Leukemia
Lymphoma
The most common cause of radiation-related pneumonitis, however, is the whole-body type of radiation needed to prepare a person for a bone marrow transplant.

Aspiration
Aspiration occurs if you inhale foreign matter into your lungs. Stomach contents, such as ingested food or liquid, can sometimes cause pneumonitis.

**RISK FACTORS**

By Mayo Clinic staff

Occupations or hobbies
Some occupations and hobbies carry higher risks of pneumonitis, including:

Farming. Many types of farming operations expose workers to aerosolized mists and pesticides. Inhaling airborne particles from moldy hay is one of the most common causes of occupational pneumonitis. Mold particles also can be inhaled during harvests of grain and hay. Bird handling. Poultry workers and people who breed or keep pet birds are often exposed to droppings, feathers and other materials that can cause pneumonitis. Hot tubs and humidifiers. Moldy conditions in hot tubs can trigger pneumonitis, because the bubbling action makes a mist that can be inhaled. Home humidifiers are another common reservoir for mold.Medical procedures

Surgical anesthesia. Undergoing general anesthesia relaxes your throat muscles and increases your risk of inhaling stomach contents. That's why people need to fast for a number of hours before receiving general anesthesia.Cancer treatment. Some chemotherapy drugs can cause pneumonitis, as can radiation therapy to the lungs. The combination of the two increases the risk. Complications

**COMPLICATIONS** I DONT MEAN TO SCARE YOU BUT TELL YOUR DOCTOR YOU WANT MORE INFO ON THIS

By Mayo Clinic staff

Pneumonitis that goes unnoticed or untreated can cause irreversible lung damage. Normally, air sacs within your lungs stretch and relax with each breath. Chronic inflammation of the thin tissue lining each air sac can make the air sacs scar and become inflexible — stiff like a dried sponge. This is called pulmonary fibrosis. In severe cases, pulmonary fibrosis can cause heart failure, respiratory failure and death.

I HOPE THIS HELPS YOU OUT.
