CHICAGO — Kidney disease increases the risk for diabetes, not just the other way around, a study of the Washington University at St. Louis has found.
Researchers at the university found that kidney dysfunction can lead to diabetes, and that a waste product called urea plays a role in the two-way link between the two diseases.
The study involved the analysis of medical records over a five-year period for 1.3 million adults who did not have diabetes. About 9 percent had elevated urea levels, a sign of reduced kidney function. That’s the same rate as in the general population.
People with high urea levels were 23 percent more likely to develop diabetes than those with normal urea levels, the study found.
“The risk difference between high and low levels is 688 cases of diabetes per 100,000 people each year, which means that for every 100,000 people, there would be 688 more cases of diabetes each year in those with higher urea levels,” said study senior author Ziyad Al-Aly, an assistant professor of medicine at Washington University School of Medicine in St. Louis.
“We have known for a long time that diabetes is a major risk factor for kidney disease, but now we have a better understanding that kidney disease, through elevated levels of urea, also raises the risk of diabetes,” Al-Aly said.
“When urea builds up in the blood because of kidney dysfunction, increased insulin resistance and impaired insulin secretion often result,” he said.
The findings about the role of urea may help improve treatment and possibly prevent diabetes. The study has been published online in the journal Kidney International. (Xinhua)

Bad disease. In July of 2017. it was discovered that I got type 2 diabetes, By the end of the July month. I was given a prescription for the Metformin, I stated with the ADA diet and followed it completely for several weeks but was unable to get my blood sugar below 140, Without results to how for my hard work. I really panicked and called my doctor. His response?? Deal with it yourself, I started to feel that something wasn’t right and do my own research, Then I found Lisa’s great blog (google ” How I freed myself from diabetes ” ) .. I read it from cover to cover and I started with the diet and by the next week. my blood sugar was 100, Since then. I get a fasting reading between the mid 70s and 80s, My doctor was very surprised at the results that. the next week. he took me off the Metformin drug, I lost 16 pounds in my first month and lost more than 3+ inches off my waist and I’m able to work out twice a day while still having lots of energy. The truth is that we can get off the drugs and help myself by trying natural methods..
