How does hyperglycemia cause oxidative stress
WebOxidative stress induced by reactive oxygen and nitrogen species is critically involved in the impairment of beta-cell function during the development of diabetes. Because of their low antioxidant capacity, beta-cells are extremely sensitive towards oxidative stress. WebStress hyperglycemia (also called stress diabetes or diabetes of injury) is a medical term referring to transient elevation of the blood glucose due to the stress of illness. It usually …

WebApr 2, 2024 · Diabetes, being a metabolic disease dysregulates a large number of metabolites and factors. However, among those altered metabolites, hyperglycemia is considered as the major factor to cause an increase in oxidative stress that initiates the pathophysiology of retinal damage leading to diabetic retinopathy. WebChronic hyperglycemia causes β-cell defects by the excess accumulation of glucose intracellularly, and this leads to ER and mitochondrial stress. ER stress activates the unfolded protein response which leads to cell death, while excess glucose substrate in the mitochondria leads to excessive ROS production.
