Study Finds Higher Urea and Potassium Levels in People With Diabetes

A comparative cross-sectional study involving 300 individuals examined differences in kidney function markers and electrolyte levels between people with diabetes and healthy participants. The study included 150 people with diabetes and 150 healthy individuals. Researchers found that the diabetes group had higher mean creatinine and urea levels, while potassium was also higher. In contrast, sodium and calcium levels were lower compared with the healthy group. The researchers noted that although several differences were statistically significant, the absolute differences were relatively small.

The study also found weak correlations between random blood glucose and some laboratory measures, with the strongest reported relationship being a moderate negative correlation between blood glucose and sodium. Logistic regression analysis identified urea, uric acid, sodium and potassium as independently associated with diabetes. However, researchers cautioned that the findings do not prove that changes in blood glucose directly cause kidney or electrolyte abnormalities. Since the study was cross-sectional, further longitudinal research is needed to understand the clinical significance and direction of these associations.
