In adults with obesity taking semaglutide for 12 months, measurable improvements were seen in blood sugar, cholesterol, blood pressure, liver enzymes, and cardiovascular risk indicators.
Mechanism
Synthesis from 1 study
When people lose weight with semaglutide, their fat tissue becomes less inflamed and stops dumping fat into the liver and muscles. This lets the body respond better to insulin, which lowers blood sugar, cleans up cholesterol, and reduces blood pressure—all without the drug directly targeting those...
Most probable mechanism
Losing weight reduces fat stored in the wrong places like the liver and around organs, which lowers inflammation and lets the body use insulin better, improving blood sugar, cholesterol, and blood pressure.
Semaglutide activates GLP-1 receptors in the hypothalamus and brainstem, reducing appetite and increasing satiety, leading to sustained caloric deficit and weight loss.
Reduction in adipose tissue mass decreases secretion of pro-inflammatory cytokines such as TNF-alpha and IL-6 from adipocytes and macrophages within fat tissue.
Decreased systemic inflammation reduces insulin resistance in skeletal muscle and liver, improving glucose uptake and suppressing hepatic glucose production.
Reduction in ectopic lipid accumulation in the liver lowers hepatic steatosis, improving liver enzyme levels and reducing de novo lipogenesis.
Improved insulin sensitivity and reduced lipid flux enhance endothelial function and reduce vascular resistance, contributing to lower blood pressure.
Lower circulating free fatty acids and improved hepatic lipid metabolism reduce VLDL production and increase HDL clearance, improving lipid profiles.
