 The human body is exposed to agents that produce free radicals which cause oxidation of cellular machinery, leading to a condition known as oxidative stress. This imbalance can result in pathological conditions such as diabetes, and various biomarkers like lipids, proteins, DNA damage, glutathione, catalane and superoxide dismutase are affected. Oxidative stress-induced complications of diabetes include stroke, neuropathy, retinopathy and nephropathy. This article was authored by Asmadullah, Abad Khan and Ismail Khan.
