Chronic kidney disease (CKD) is an important public health challenge and the prevalence of CKD is estimated to be 10 to 14% in the general population; these rates are expected to increase modestly over the next 20 years. African Americans, American Indians, Hispanics, and South Asians, specifically, people from developing nations like Pakistan, Sri Lanka, Bangladesh, and India, are at increased risk of having CKD. CKD is chiefly defined as presence of kidney damage or estimated glomerular filtration rate (GFR)<60 ml/min/1.73 m2 persisting for 3 months or more, regardless of the cause and it is classified into stages according to the level of GFR.
