Diabetic neuropathy is a prevalent and perilous condition that individuals with diabetes may experience. It occurs when nerves sustain greater damage, resulting in pain and sensory loss. According to recent research, oxidative stress plays a major role in the onset of diabetic neuropathy. Examining the damaging consequences of oxidative stress on neurones in diabetics is the aim of this article. By increasing the formation of reactive oxygen species (ROS) and reducing antioxidant defence systems, excessively high blood sugar levels cause oxidative stress. Oxidative stress compromises proteins, lipids, and DNA, disrupting homeostasis and ultimately impairing the structure and function of neurones. Diabetic neuropathy is a prevalent and painful condition affecting individuals with diabetes. Nerve injury results in pain and sensory loss. Recent study indicates that oxidative stress is a fundamental factor in the development of diabetic neuropathy. The objective of this overview is to investigate the detrimental effects of oxidative stress on nerves in diabetic individuals. Excessively elevated blood sugar levels induce oxidative stress by augmenting ROS and diminishing antioxidant defence mechanisms. This imbalance adversely affects the structure and function of neurones over time by degrading proteins, lipids, and DNA via oxidation. By enhancing our understanding of biological mechanisms, we may develop more personalised medical treatments. A crucial method for pharmacological management of diabetic neuropathy is the regulation of oxidative stress.
