Abstract: Diabetic Nephropathy (DN) is known as one of the driving sources of End-Stage Renal
Disease (ESRD). DN prevalence continues to increase in every corner of the world andthat has
been a major concern to healthcare professionals as DN is the key driver of Diabetes Mellitus (DM)
morbidity and mortality. Hyperglycaemia is closely connected with the production of Reactive
Oxygen Species (ROS) that cause oxidative stress response as well as numerous cellular and molecular
modifications. Oxidative stress is a significant causative factor to renal damage, as it can activate
other immunological pathways, such as inflammatory, fibrosis, and apoptosis pathways. These
pathways can lead to cellular impairment and death as well as cellular senescence. Natural substances
containing bioactive compounds, such as polyphenols, have been reported to exert valuable
effects on various pathological conditions, including DM. The role of polyphenols in alleviating
DN conditions has been documented in many studies. In this review, the potential of polyphenols
in ameliorating the progression of DN via modulation of oxidative stress, inflammation, fibrosis,
and apoptosis, as well as cellular senescence, has been addressed. This information may be used as
the strategies for the management of DN and development as nutraceutical products to overcome
DN development.
