Bronchiolitis Obliterating – Causes, Symptoms and Treatments

Bronchiolitis Obliterating – Causes, Symptoms and Treatments that we should not ignore. In addition, bronchiolitis obliterans is a serious and irreversible lung disease that causes inflammation and blockage of the small airways in the lungs: the bronchioles. It is also known as obliterative bronchiolitis, and its symptoms may closely resemble symptoms of chronic obstructive pulmonary disease (COPD).




Oblique bronchiolitis became more known in 2000 when Missouri health authorities asked the federal Centers for Disease Control and Prevention (CDC) to help them investigate cases in former workers at the Jasper microwave popcorn plant, Mo.

Ultimately, health authorities tracked the outbreak of inhaled diacetyl, the chemical that gives the microwave popcorn its buttery flavor. Of these cases, obliterating bronchiolitis was nicknamed “popcorn lung.

By 2015, the CDC has also identified workers in a coffee processing plant suffering from bronchiolitis obliterans. There, the cause appears to be volatile organic compounds released by large amounts of coffee beans when they are wet.

Causes of Obliviating Bronchiolitis:

In some people, it is unclear what causes bronchiolitis obliterans. However, several possible causes have been identified. These include:

  1. Inhalation of toxic fumes;
  2. Respiratory infections;
  3. Disorders of connective tissue, such as rheumatoid arthritis;
  4. Reaction to certain medicines;

The condition also develops in some people after transplantation of bone marrow, lung or heart and lung. One study found that about 10 percent of people who received a bone marrow transplant from a donor developed bronchiolitis obliterans within five years after transplantation, while other researchers note that 50 percent of lung transplant recipients develop the condition within five years .

Symptoms of Bronchiolitis Obliterating:

Although it may take years for the symptoms of the disease to appear after a transplant, the following symptoms (closely mimicking COPD) may appear within two to eight weeks after exposure to toxic fumes or after a lung infection :

  1. Dry cough;
  2. Wheezing;
  3. Dyspnoea;
  4. Fatigue;

Treatment for Bronchiolitis Obliterating:

Like COPD, bronchiolitis obliterans are irreversible. The following treatment, however, may help decrease your progression:

Rapid removal of exposure to irritant toxin (if an inhaled toxin is the cause of the disease);

  1. Medications, including corticosteroids and drugs that reduce the body’s immune response (immunosuppressants);
  2. Pulmonary transplantation;

As bronchiolitis obliterans can be fatal if left untreated, early intervention is essential for the successful treatment of the disease.

Bronchiolitis obliterans is not the same condition as the bronchiolitis obliterans that organize pneumonia, despite similar names. Bronchiolitis obliterans that organize pneumonia is a rare form of noninfectious pneumonia that causes extensive inflammation in the bronchioles of the lungs.
