Dear Reader,
While the official release date for The Body’s Keepers is Feb. 13, as a friend of Mayo Clinic Press, you can preorder your copy today and receive a special discount.
The kidneys are extraordinary organs—in many ways the keepers of the human body’s delicate equilibrium. On a given day, minute by minute, they purify the body of toxins it encounters from diet, climate, activity, and injury. They allow us to be and to move in the world. And yet most of us know so very little about these extraordinary vessels nestled in our bodies—indeed millions of us only really learn about them when they stop working.
Nearly a million Americans every year have end-stage kidney disease; about 37 million have some form of chronic kidney disease, an ailment that, until relatively recently, would simply kill those afflicted with it. |
