The stress induced hyperglycemia of pathophysiologycal significance in stroke patients

Stress induced hyperglycemia is a transient increase glucose blood level during the acute phase of ischemic stroke. Hyperglycemia enhances initiated by cerebral ischemia neuronal death, blood-brain barrier destruction, leads to hemorrhagic transformation, promotes the formation of brain edema. This increases the size of ischemic penumbra and increases the severity of neurological deficit. Stress hyperglycemia as a consequence of stress-realizing system activation is a significant pathogenetic link in ischemic stroke patients.
