ByssinosisCotton worker's lung; Cotton bract disease; Mill fever; Brown lung disease
Byssinosis is a disease of the lungs brought on by breathing in cotton dust or dusts from other vegetable fibers such as flax, hemp, or sisal while at work.
Breathing in (inhaling) the dust produced by raw cotton can cause byssinosis. It is most common in people who work in the textile industry.
Those who are sensitive to the dust can have an asthma-like condition after being exposed.
Occupational asthma is a lung disorder in which substances found in the workplace cause the airways of the lungs to swell and narrow. This leads to ...
Methods of prevention in the United States have reduced the number of cases. Byssinosis is still common in developing countries. Smoking increases risk of developing this disease. Being exposed to the dust many times can lead to chronic (long-term) lung disease and shortness of breath or wheezing.
Symptoms may include any of the following:
- Chest tightness
Wheezing is a high-pitched whistling sound during breathing. It occurs when air moves through narrowed breathing tubes in the lungs.
Symptoms are worse at the beginning of the work week and improve later in the week. Symptoms are also less severe when the person is away from the workplace.
Exams and Tests
Your health care provider will take a detailed medical history and ask you many questions to find out whether your symptoms relate to certain exposures or times of exposure. The provider will also do a physical exam, paying special attention to the lungs.
Tests that may be ordered include:
A chest x-ray is an x-ray of the chest, lungs, heart, large arteries, ribs, and diaphragm.
CT scan chest
CT scan chest
A chest CT (computed tomography) scan is an imaging method that uses x-rays to create cross-sectional pictures of the chest and upper abdomen....
Pulmonary function tests
Pulmonary function tests
Pulmonary function tests are a group of tests that measure breathing and how well the lungs are functioning.
The most important treatment is to stop being exposed 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.
Medicines used for asthma, such as bronchodilators, usually improve symptoms. Corticosteroid drugs may be prescribed in more severe cases.
Stopping smoking is very important for people with this condition. Breathing treatments, including nebulizers, may be prescribed if the condition becomes long-term. Home oxygen therapy may be needed if blood oxygen level is low.
Physical exercise programs, breathing exercises, and patient education programs are often helpful for people with a chronic lung disease .
Lung disease is any problem in the lungs that prevents the lungs from working properly. There are three main types of lung disease:Airway diseases -...
Symptoms usually improve after stopping exposure to the dust. Continued exposure can lead to reduced lung function. In the United States, worker's compensation may be available to people with byssinosis.
Chronic bronchitis may develop.
When to Contact a Medical Professional
Call your 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.

The major features of the lungs include the bronchi, the bronchioles and the alveoli. The alveoli are the microscopic blood vessel-lined sacks in which oxygen and carbon dioxide gas are exchanged.
