Myths vs facts: hsCRP and blood sugar

There are many myths about the link between hsCRP (high-sensitivity C-reactive protein) and blood sugar. A common myth is that elevated hsCRP directly causes high blood sugar. In reality, hsCRP is an inflammatory marker associated with insulin resistance – but not causal. Chronic low-grade inflammation can impair insulin action, potentially raising blood sugar over time. However, hsCRP is not a blood sugar test; it indicates systemic inflammation from various causes (infection, smoking, obesity). Another myth: a normal hsCRP rules out diabetes. Fact: many people with type 2 diabetes have normal hsCRP. The evidence for the association is moderate – based on epidemiological studies, not RCTs. For practice: hsCRP can serve as a risk marker but does not replace glucose measurements. To optimize blood sugar, rely on fasting glucose, HbA1c, and possibly an oral glucose tolerance test. MyBody-X tests provide complementary but not definitive information. Caution: single biomarkers should never be overinterpreted.
