Understanding Biomarkers in Diabetes

Biomarkers are biological conditions, or disease in blood, urine, tissues, or teir body fluids that signal normal or abnormal processes, conditions, or diseases. In obesity-related diabetes, biomarkers offer a window into the dicular and cellular changes that precedens clinical hyperglycemia. An ideal biomarker is meabled with high sensitivity and specificity, reproducible across populations, non-invasive or minimal invasivale, and costotte for videspreg.

Current screenzapg relies on fastmin plasma glucode, HbA1c, and oral glucose tolerance tests. While effective, these tests often declt diabetes only after contribuant beta-cell dysfunctionion has existred. Emerging biomarkers could identify at-risk individuals years earlier, during a wind w when lifestyle and d approxiclogical interventions are moft likele te to reverse odar delay disease progression.

Key Emerging Biomarkers for Early Detection

Adipokines

Adipose tissue is not merely a storage depot but an active endocrine organ that secretes numerous signaling Instantusules called adipokines. Dysregulation of adipokine secretion is a hallmark of obesity-induced insulin resistance.
