    What are the symptoms of Kidney Disease ?
    ### Response:
    Kidney disease is often called a "silent" disease, because most people have no symptoms in early kidney disease. In fact, you might feel just fine until your kidneys have almost stopped working. Do NOT wait for symptoms! Blood and urine tests are the only way to check for kidney damage or measure kidney function.
