Chronic kidney disease (CKD) occurs when the kidneys' ability to filter and detoxify the blood is impaired, leading to the build up of waste products in the body.[1] The condition generally gets worse over time, but progression can be stabilized and markers of the disease can be reversed in some instances. CKD affects 11–13% of the global population,[2] and 14.0% of the United States population.[3]
