Causes of Goodpasture Syndrome
The body's immune system produces antibodies, which are proteins that help fight infections. However, in Goodpasture's Syndrome the body makes antibodies that attack and damage the lining of your lungs and kidney. As a result, if you have this disease, you may start to experience fatigue, weakness and loss of appetite. However, the disease may quickly progress and you may bleed from the lungs and cough up blood. It may also lead to inflamed kidneys (glomerulonephritis). It is not exactly known why your antibodies begin to attack your own lungs and kidneys. Factors that may trigger the disease include exposure to viral lung infections, smoking and breathing in vapors from organic solvents.

This problem is most common in people between the ages of 20 and 30 or after age 60. It is not contagious and it is more common in men and Caucasians. Sometimes one will suffer from these symptoms as a result of other diseases, such as lupus erythematosus or Wegener's granulomatosis.
