Question: What causes Goodpasture Syndrome ?
Answer: The causes of Goodpasture syndrome are not fully understood. People who smoke or use hair dyes appear to be at increased risk for this condition. Exposure to hydrocarbon fumes, metallic dust, and certain drugs, such as cocaine, may also raise a persons risk. Genetics may also play a part, as a small number of cases have been reported in more than one family member.
