Mechanisms Linking Obesity with Non-Alcoholic Fatty Liver Disease (NAFLD) and Cardiovascular Diseases (CVDs)-The Role of Oxidative Stress.

Abstract

Obesity concerns a wide range of the population, tending to become a major factor for diseases' progression and fatality rate increases, with implications concerning the cardiovascular system's deterioration. Obesity is closely linked with metabolic derangements concerning lipid storage and circulation, and the cellular metabolism affecting most of the internal organs, especially liver and cellular function. In this current study, an analysis of the linking mechanisms between obesity, lipid deterioration, liver, and lipid tissue homeostasis will be performed, with special attention to the pathophysiological characteristics of these detrimental effects on the NAFLD (non-alcoholic fatty liver disease) and the cellular function of the endothelial blood cells, with special reference to the additional burdening of obesity on the autonomous nervous system signaling, and the resulting hypertension. Despite the very complex and pluripotent pathogenic mechanisms with which obesity is intervening in these processes, it could be safely deduced that metabolic and lipid transport manipulation could serve as a crucial factor towards the cellular and tissue function improvement, as the interlinkages in the mechanisms, although highly analyzed, have not been completely deciphered until now.
