Chronic kidney disease or CKD describes a gradual loss of kidney function and emerged as a significant public health burden as it is associated with risk of progression to end stage kidney disease requiring dialysis support. In Malaysia, dreadfully the number of cases requiring dialysis support each year continue to increase and impose a great burden on the healthcare budget. The increasing numbers are attributed by increasing prevalence of chronic diseases such as diabetes, high blood pressure and ageing population in the country.
Risk factors for development of CKD including being older age, diabetes, high blood pressure, heart disease, smoking, obesity and family history of kidney disease. CKD can be caused by various underlying medical illnesses such as diabetes, high blood pressure, inflammation to the kidney’s filtering unit or glomeruli (called glomerulonephritis) or the kidney’s tubules and surrounding structures (called interstitial nephritis) from medication, infection and autoimmune diseases, polycystic kidney disease (PKD), prolonged obstruction in the urinary tract from enlarged prostate, kidney stone and cancers, infection to the kidney (pyelonephritis) and vesicoureteral reflux (a condition that causes urine to go back up into your kidneys).
