how does a glp 1 agonist work Frontiers Top GLP-1 Agonists Balance Weight

It has multiple actions including: potentiation of glucose-mediated insulin secretion mechanisms identified: increased -cell proliferation, resulting in an increase -cell mass (Fusco et al, 2017) stimulation of insulin biosynthesis at the translational level, helping to maintain -cell insulin stores and secretory capacity (Baggio & Drucker, 2007) because the GLP-1 effect is glucose-dependent (there is more insulin release when glucose levels are elevated, but less effect when glucose levels are normal), GLP-1 agonists have a lower risk for producing hypoglycemia compared to sulfonylureas (that chronically stimulate insulin release, independent of glucose concentration) suppression of postprandial glucagon release Evidence indicates that stimulation of pancreatic cells by GLP-1 increases their glucose sensitivity, resulting in less glucagon release at any glucose level (Baggio & Drucker, 2007)

Ozempic is commonly used for weight loss and has been shown to reduce weight by about 10-15% over a year

bariatric procedure volumes declined 11.4% in 2025 reversing a two-decade growth trend as semaglutide and tirzepatide provide comparable weight loss outcomes for class I and class II obesity without surgical risk, recovery time, or nutritional deficiency complications

Additionally, they suppress glucagon secretion, a hormone that raises blood glucose levels, and delay gastric emptying, which helps to prevent postprandial glucose spikes
