The Claim

In men aged 60 to 79 without diabetes, plasma copeptin levels above 6.79 pmol/L are associated with a 78% higher risk of developing type 2 diabetes over a 13-year period, independent of waist circumference, blood pressure, triglycerides, and C-reactive protein.

In plain English

Men aged 60 to 79 without diabetes who have plasma copeptin levels above 6.79 pmol/L have a 78% higher incidence of type 2 diabetes over 13 years compared to those with lower levels, even when accounting for waist size, blood pressure, triglycerides, and C-reactive protein.

See the scientific wording

In men aged 60 to 79 without diabetes, plasma copeptin levels above 6.79 pmol/L are associated with a 78% higher risk of developing type 2 diabetes over 13 years, independent of traditional risk factors such as waist circumference, blood pressure, triglycerides, and C-reactive protein, suggesting that the arginine vasopressin system may contribute to diabetes pathogenesis.

Why this might work

When the brain releases too much of a stress hormone called arginine vasopressin, it triggers inflammation, damages blood vessels, and forces the pancreas to work harder to produce insulin. Over time, this wears out insulin-producing cells and makes the body less able to use insulin, causing blood sugar to rise and leading to type 2 diabetes.

  1. Study: Copeptin, Insulin Resistance, and Risk of Incident Diabetes in Older Men

    In older men, higher levels of a blood marker called copeptin are linked to a much higher chance of getting type 2 diabetes over time—even if they’re not overweight or have high blood pressure—suggesting that a stress-related hormone system in the body might help cause diabetes.
