Type 2 Diabetes Mellitus Pathophysiology: Insulin Resistance & The 3 Ps (Complete Guide)

Type 2 Diabetes Mellitus: The Complete Pathophysiology & Cellular Breakdown ​Type 2 Diabetes Mellitus is far more than just elevated blood glucose; it is a systemic metabolic collapse that silently damages organs years before clinical symptoms emerge. ​In this comprehensive 3D clinical guide, PathoPulse breaks down the complete pathophysiology of Type 2 Diabetes. We explore normal glucose homeostasis, the dual-defect mechanism of peripheral insulin resistance and pancreatic beta-cell apoptosis (via amylin toxicity), the renal mechanics driving the classic "Three Ps" (Polyuria, Polydipsia, and Polyphagia), and how chronic hyperglycemia causes widespread microvascular and macrovascular decay through AGEs. ​⏱️ Video Chapters: 0:00 The Silent Metabolic Crisis (Global Impact) 0:34 The Dual-Defect Mechanism Explained 1:04 Normal Physiology: The Insulin & GLUT4 Pathway 2:22 Peripheral Insulin Resistance & Visceral Adiposity 3:16 Cellular Deafness & Signaling Failure 3:58 Pancreatic Overdrive & Beta-Cell Apoptosis (Amylin Plaques) 5:06 The Classic Clinical Triad (The 3 Ps) 5:17 Renal Transport Maximum & Glycosuria 5:50 Osmotic Diuresis, Polyuria & Polydipsia 6:16 Cellular Starvation & Polyphagia 6:38 Vascular Decay: Advanced Glycation End-Products (AGEs) 7:25 Microvascular vs. Macrovascular Complications 7:50 Clinical Management & Outro ​🔔 Subscribe to PathoPulse: Stay clinical, stay curious.
