51
Q

Describe Goodpasture’s disease as if you were talking to a patient

A

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).

A

A type of nephrotic syndrome.
