byssinosis
Information, Symptoms, Treatments and Resources
Byssinosis is a disease of the lungs caused by breathing in cotton dust or dusts from other vegetable fibers such as flax, hemp, or sisal while at work.
See also: Occupational asthma
Breathing in the dust produced in the textile industry can cause byssinosis. People who are sensitive can have an asthma-like condition after being exposed to dust. In those with asthma, being exposed to the dust makes breathing more difficult, but in byssinosis, the symptoms usually go away by the end of the work week. After long periods of exposure, symptoms can continue throughout the week without improving.
Methods of prevention in the U.S. have reduced the number of cases, but byssinosis is still common in developing countries. Smoking increases the risk for this disease. Being exposed to the dust many times can lead to chronic lung disease and shortness of breath or wheezing.
- Chest tightness
- Cough
- Wheezing
Symptoms will get worse at the beginning of the work week, and then improve while you are away from the workplace, or later in the work week.
Your health care provider will take a detailed medical history, and will ask many questions to try to find out whether your symptoms relate to certain exposures or times of exposure. The health care provider will also do a physical exam, with special attention to the lungs. Other tests include:
The most important treatment is to stop exposure to the dust. Reducing dust levels in the factory (by improving machinery or ventilation) will help prevent byssinosis. Some people may have to change jobs to avoid further exposure.
Medications such as bronchodilators will usually improve symptoms. Corticosteroids may be prescribed in more severe cases.
Stopping smoking is very important for people with this condition. Respiratory treatments, including nebulizers and postural drainage, may be prescribed if the condition becomes chronic. Home oxygen therapy may also be needed if blood oxygen levels are low.
Physical exercise programs, breathing exercises, and patient education programs are often very helpful for people with a chronic lung disease.
Symptoms usually improve after stopping exposure to the dust. Continued exposure can lead to damaged lung function. In the U.S., worker's compensation may be available to people with byssinosis.
Call your health care provider if you have symptoms of byssinosis.
Controlling dust, using face masks, and other measures can reduce the risk. Stop smoking, especially if you work in textile manufacturing.
