Low kidney function, also known as chronic kidney disease, is treated with medications that control high blood pressure, high cholesterol, anemia and swelling, notes Mayo Clinic. Low functioning kidneys that are in end-stage kidney disease require a kidney transplant or artificial blood filtration by dialysis.
Chronic kidney disease results in a gradual loss of kidney function, according to the National Kidney Foundation. Individuals with the disease are unable to filter waste products and excess water that build up in the blood. Waste products that accumulate in the blood produce symptoms that include anemia, insomnia, high blood pressure and muscle cramping.
The specific treatment chosen to treat chronic kidney disease depends on the underlying cause of the disease, notes the National Kidney Foundation. While several conditions contribute to chronic kidney disease, diabetes and high blood pressure account for up to two-thirds of the cases.
Chronic kidney disease that is caused by high blood pressure is treated with medications, such as agiotensin-converting enzyme inhibitors, diuretics and a low-salt diet, says Mayo Clinic. Disease cases caused by anemia are treated with erythropoietin hormone and iron supplements. A diet with lower protein is sometimes recommended to limit the amount of waste that the kidneys must remove from the blood.
