Doctors don’t know for sure what causes sarcoidosis. They think that sarcoidosis may be caused by a combination of genetics (family history) and environmental factors (things around you).  Doctors do know that being near certain things may boost your risk of getting sarcoidosis:

  • Wood-burning stoves
  • Silica (a mineral)
  • Insecticides
  • Mould
  • Certain bacteria in your lungs
