The kidneys are essential organs: they filter and eliminate the waste products of metabolism they have a central role in controlling blood pressure and fluid balance in the body they produce the key hormone that stimulates the bone marrow to manufacture red blood cells.
People with very poor kidney function require some form of artificial kidney support (dialysis) or a kidney transplant. The increasing numbers of people with Type 2 diabetes has meant the demand for these facilities has been steadily climbing for several years. Because the kidneys have a central role in controlling blood pressure, it's common for people with diabetic kidney disease to have raised blood pressure. High blood pressure accelerates the decline in kidney function in nephropathy – in other words the two problems multiply each other’s effect. By lowering blood pressure, diabetic kidney disease can be slowed down. |
