Glucose Homeostasis Aging

Glucose homeostasis aging describes age-associated deterioration in regulation of blood glucose levels. In healthy systems, glucose balance is maintained through coordinated insulin secretion, tissue uptake, and hepatic glucose production. Aging disrupts this balance through reduced insulin sensitivity, altered pancreatic function, and impaired glucose clearance. Mitochondrial dysfunction and inflammation further compromise glucose handling. Glucose homeostasis aging leads to increased glucose variability, reduced metabolic flexibility, and heightened disease risk. Even modest dysregulation accelerates cellular damage through oxidative stress and glycation. Glucose homeostasis aging affects energy availability, cognitive function, and vascular health. Understanding age-related changes in glucose regulation supports strategies to preserve metabolic stability and prevent downstream aging-related complications.
