Disorders in the funciont of kidneys are very common in people with diabetes. There may be several underlying factors – some related to diabetes, some not. The underlying factors of diabetes-related kidney damage include genetic disposition and, normally, chronically high blood sugar and blood pressure or a atherosclerosis.
To some degree, the increased prevalence of kidney disease is explained by age, because approximately 45% of people with diabetes are aged 70 or older. Kidney diseases are more common in the elderly.
