Myths vs facts: hsCRP and Blutzucker

Myth: Elevated hsCRP (high-sensitivity C-reactive protein) directly means your blood sugar is out of control or you have diabetes. Fact: hsCRP is a non-specific inflammatory marker. Elevated levels are commonly associated with insulin resistance and type 2 diabetes, but also with infections, smoking, obesity, or stress. The association between hsCRP and blood glucose is observational, not causal. A single hsCRP value alone is neither diagnostic for diabetes nor for impaired glucose tolerance. Fasting glucose, HbA1c, and oral glucose tolerance test remain the standard parameters. Genetic variants (e.g., rs1205) influence baseline hsCRP, but the effect on blood sugar is small. Lifestyle factors such as diet, exercise, and weight management lower both hsCRP and blood glucose. Caution against overinterpretation: Elevated hsCRP is a risk indicator, not a direct blood sugar test. The evidence supports a moderate correlation, not causation.
