How Diabetes Derails Normal Blood Clotting

Blood clotting, or coagulation, is a carefly orchestrates process designed to stop bleeding after vascular condity. Under normal conditions, platelets adhere to expose subenflevial tissue, agregate, and release chemical signals that activate thee coagulation cascade. A fibrin mesh then stabilizes thee platelet plug. In diabetetes, high food glucose, insulin resistance, and methavitaid diffitititiets everystage of this process, shifting balance to a protroptic state.
