What is the mechanism of action of GLP-1 medicines?

GLP-1 medicines work by mimicking the action of a hormone called glucagon-like peptide-1. They stimulate the pancreas to release insulin when blood sugar levels are high, which helps lower blood sugar. Additionally, they reduce the amount of glucagon released (a hormone that raises blood sugar) and slow down gastric emptying, which means food stays in the stomach longer. This helps you feel fuller for a longer time, supporting weight management. Understanding how these medicines work can help you make informed decisions about your diabetes management.
