Prediabetes Tied to Kidney Damage

Even prediabetes can damage a person's kidneys, concludes new research published in the _American Journal of Kidney Disease. _

Researchers at University Hospital of North Norway say that even before a person is diagnosed with diabetes, they could be suffering kidney damage if they have higher-than-normal blood sugar levels.

Diabetes is well known as a major risk factor for kidney disease. Around 30 percent of people with type 1 diabetes and 10 to 40 percent of those with type 2 diabetes will go on to experience kidney failure. Approximately 86 million people in the U.S. have prediabetes -- blood sugar levels that are higher than normal, but not high enough to be diagnosed as diabetes.

For the study, the team analyzed 1,324 adults between the ages of 50 and 62 in order to gain a better understanding of whether prediabetes is linked to kidney damage. At the study's baseline, 595 of the participants had prediabetes. When following up over five years and after adjusting for participants' lifestyle and use of medications, the researchers found those with prediabetes had a higher measure of hyperfiltration-an abnormality that can lead to kidney damage and failure over time.

The researchers believe that these findings are a strong indication that prediabetes may be a precursor to kidney disease.
