GLP-1

GLP-1

GLP-1 stands for glucagon-like peptide-1, which is a hormonal pathway that controls appetite and blood sugar regulation. GLP-1 drugs mimic these natural processes in the body.

 The U.S. Food and Drug Administration (FDA) has approved GLP-1 drugs for treating type 2 diabetes and obesity, but scientists are exploring other potential uses, such as for addiction.

 Although GLP-1s can be very effective, they aren’t for everyone. Diet and lifestyle choices are important for success on these lifelong medications.
