Oxidative stress is recognized as a central pathological mechanism contributing to the progression of diabetes and its associated complications. Persistent hyperglycemia promotes excessive reactive oxygen species (ROS) production, mitochondrial dysfunction, chronic inflammation, and apoptosis, ultimately leading to tissue injury across multiple organs.
Increasing evidence suggests that oxidative stress plays a critical role in diabetic nephropathy, cardiomyopathy, retinal injury, impaired wound healing, and reproductive dysfunction. As a result, oxidative stress-related biomarkers and inflammatory pathways have become widely investigated targets in diabetes research.
