Clinical Information
  • A condition of bronchoconstriction resulting from hypersensitive reaction to inhaled dust during the initial processing of cotton, flax, or hemp in the textile industry. Symptoms include wheezing and tightness in the chest.
  • Airway obstruction due to the dust inhaled during the processing of cotton.
  • An occupational lung disorder caused by exposure to cotton dust. It occurs more commonly in workers in the textile industry. Signs and symptoms include chest tightness, cough and wheezing. The symptoms tend to get worse at the beginning of the week and subside by the end of the week.
