Yes — GLP, specifically GLP-1 (glucagon-like peptide-1), plays a direct role in insulin regulation. It is a naturally occurring hormone released by the intestine after eating. GLP-1 stimulates the pancreas to secrete insulin in response to elevated blood glucose levels, while simultaneously suppressing the release of glucagon, the hormone that increases blood sugar. This dual action helps maintain healthy glucose balance and supports proper metabolic function.
In people with type 2 diabetes, GLP-1 secretion or response may be impaired, leading to unstable blood sugar levels. This is why GLP-1 receptor agonists — medications that mimic the action of natural GLP-1 — are widely used to improve insulin regulation, lower blood glucose, and promote weight loss. In summary, GLP is not insulin itself, but a key hormone that controls how and when insulin is released, making it vital in both diabetes treatment and metabolic health.
