Chronic kidney disease (CKD) is an increasingly prevalent global public health problem. Estimates suggest that up to 13% of the worldwide population (approximately 846 million people) is affected by CKD stages I-V, with the majority of patients in stage III disease. Further, the World Health Organization believes that CKD will be the fifth most common chronic disease in 2040.

CKD is associated with increased healthcare expenditure and is an independent risk factor for cardiovascular disease (CVD) and morbidity as well as other serious complications, including hypertension, anemia, and renal bone disease, all of which can lead to premature mortality and decreased quality of life. Hypertension, obesity, diabetes, and primary renal disorders can all accelerate the decline in renal function.
