Mechanisms through which laparoscopic sleeve gastrectomy mitigates atherosclerosis risk: a focus on visceral adipose...

Bariatric surgery is currently considered the key treatment method for patients with obesity and related complications. Among the various surgeries, laparoscopic sleeve gastrectomy (LSG) is the most widely used. Obesity is a multifactor chronic disease characterized by the accumulation of visceral adipose tissue (VAT), leading to susceptibility to cardiac metabolic diseases. Many mechanisms, including abnormal lipid metabolism, insulin resistance, inflammation, endothelial dysfunction, adipocytokine imbalance and inflammasome activation, have been identified as the basis for the relationship between obesity and atherosclerosis. Bariatric surgery, such as LSG, reduces the risk of atherosclerosis in people living with obesity by reducing energy intake, disrupting energy balance and reducing the secretion of intestinal hormones to intervene in these risk factors. This review explores the current understanding of how LSG affects VAT and its impact on the risk of atherosclerosis.
