Understanding Oxidative Stress in Diabetes

Oxidative stres aris is when thee production of reactive oxygen species (ROS) and reactive nitrogen species (RNS) exceeds the e body 's capacity to neutralize them with indigenous andd dietary antioxidants. In diabetes, this imbalance is asmified by chronic hyperglycemia, which contrains multiple pathways of free radical generation.
