DEAR DOCTORS: A recent blood test showed my creatinine levels are a bit high. My doctor said it's something we need to watch because that can be a symptom of chronic kidney disease. Is high creatinine really that big of a deal? What can you do to take care of your kidneys and get lower numbers?
DEAR READER: When it comes to general health, kidney function isn't the first thing that comes to mind. Factors such as blood pressure, blood sugar, cholesterol and cardiovascular health all get top billing. But those two bean-shaped organs, each about the size of a fist, play an integral role in keeping us alive.
