What role does CRP Entzündung play in blood sugar?

CRP (C-reactive protein) is a well-established inflammatory marker synthesized in the liver in response to interleukin-6. Chronically elevated CRP levels (≥2 mg/L) are epidemiologically linked to increased risk of type 2 diabetes and insulin resistance. The underlying pathophysiology involves inflammatory mediators disrupting insulin signaling in muscle and adipose tissue, reducing glucose uptake and increasing hepatic glucose production. However, CRP itself is not a causal factor but a surrogate marker for systemic inflammation. Evidence comes from large cohort studies and meta-analyses, but randomized intervention trials directly proving that lowering CRP improves blood glucose are lacking. In the context of consumer DNA tests or nutrigenetics, CRP is often marketed as an 'inflammation gene,' yet the predictive power of single CRP polymorphisms (e.g., rs1205) is low. Lifestyle factors (diet, exercise, sleep) have a far greater impact on both CRP and blood sugar than genetic variants. Conclusion: CRP is a useful but non-specific indicator; isolated interpretation without clinical context is misleading.
