The Claim

Serum copeptin levels are inversely correlated with estimated glomerular filtration rate (eGFR) in adults with type 2 diabetes, with a correlation coefficient of r = -0.707 (p < 0.001).

In plain English

In adults with type 2 diabetes, higher levels of copeptin in the blood are consistently linked to lower kidney filtration capacity as measured by eGFR.

See the scientific wording

Serum copeptin levels are strongly and inversely correlated with estimated glomerular filtration rate (eGFR) in adults with type 2 diabetes, with a correlation coefficient of r = -0.707 (p < 0.001), indicating that higher copeptin levels are consistently associated with reduced kidney filtration capacity.

Why this might work

High blood sugar causes the brain to signal the kidneys to hold more water, which tightens blood vessels leading into the kidney filters. This increases pressure inside the filters, damaging them over time and reducing their ability to clean the blood.

  1. Study: Copeptin as a dual biomarker in type 2 diabetes: association with glycemic control and diabetic kidney disease

    In people with type 2 diabetes, higher levels of a substance called copeptin in the blood are linked to worse kidney function — the worse the kidneys are working, the higher the copeptin levels tend to be.
