01

What is it?

GLP-1 is a natural gut hormone that helps link a meal to insulin release and other signals involved in glucose regulation and appetite. It is the biological pathway behind several medicines, but native GLP-1 and engineered GLP-1 receptor agonists are not the same substance or product. [1]

02

Potential benefits

Enhances glucose-dependent insulin secretion. Helps regulate appetite and gastric emptying. [1]

03

Evidence & its limits

That foundational experiment was conducted in isolated rat pancreas, not a human weight-loss trial. It establishes a mechanism rather than the clinical effects of every later medicine. Human outcomes, indications, and warnings must come from studies and labels for the individual drug. [1]

04

Risks & unknowns

The natural hormone is not the same product as engineered medicines. Effects and warnings vary among GLP-1 receptor agonists. [1]

05

Status & scope

This record concerns the native hormone. Approved GLP-1 receptor agonist medicines have separate product-specific indications and warnings; they are not interchangeable with the natural hormone. [1]

06

The question to ask

Does the evidence match the exact product, route, condition and outcome being discussed? Check the full record and its review dates. This summary is selective; the product label and clinical assessment contain additional warnings and contraindications.
