Blood glucose regulation via modulation of carbohydrate metabolism

Blood glucose regulation via modulation of carbohydrate metabolism is a fundamental physiological process that maintains systemic glucose levels within a tight homeostatic range (StatPearls, 2023). This regulation is primarily mediated by the endocrine pancreas, where alpha and beta cells secrete glucagon and insulin, respectively, to balance glucose production and utilization (NIH, 2022). In the postprandial state, insulin promotes glucose uptake in peripheral tissues and inhibits hepatic glucose output, while during fasting, glucagon stimulates glycogenolysis and gluconeogenesis (PubMed, 2021). Dysfunction in these regulatory mechanisms is the primary driver of diabetes mellitus, leading to chronic hyperglycemia and associated complications such as cardiovascular disease, retinopathy, and neuropathy. Pharmacological management of this process involves a wide array of drugs that target specific receptors, enzymes, and transporters—such as the GLP-1 receptor, DPP-4 enzyme, and SGLT2 transporter—to restore glycemic balance and improve patient outcomes (Nature Reviews Drug Discovery, 2020). Because this entry describes a physiological outcome or mechanism of action rather than a single molecular entity, it is classified as a biological process rather than a specific therapeutic target.

Regulation of blood glucose levels is achieved through multiple mechanisms including the stimulation of insulin secretion, enhancement of peripheral glucose uptake, inhibition of hepatic gluconeogenesis, and reduction of renal glucose reabsorption (StatPearls, 2023; PubMed, 2021).
