What role does HDL play in Blutzucker?

HDL (high-density lipoprotein) plays a significant but indirect role in blood sugar regulation. It supports insulin secretion from pancreatic beta cells, enhances insulin sensitivity in muscle and adipose tissue, and exerts anti-inflammatory effects—all of which can help maintain healthy glucose levels. Epidemiological evidence consistently links low HDL cholesterol with higher risk of type 2 diabetes. However, the causal relationship is not fully established: pharmacological interventions that raise HDL have not reliably improved glycemic control. HDL is better viewed as a marker of metabolic health rather than a direct therapeutic target. Lifestyle factors like regular exercise, a Mediterranean diet, and weight management remain the most effective strategies for blood sugar control. Measuring HDL can provide useful context, but it should not be used in isolation to assess or manage glucose metabolism.
