GLP-1 medications have multiple different mechanisms in the body that help with diabetes and weight loss, including: Increasing the amount of insulin made by the pancreas , which helps control blood sugar in patients with diabetes Decreasing the amount of excess sugar made by the pancreas , which helps control blood sugar in patients with diabetes Slowing down digestion from the stomach , which results in feeling full for longer after eating Signaling to your brain that you are full after eating , which helps suppress appetite and control cravings Tirzepatide contains an extra mechanism of action that other GLP-1 medications do not, known as GIP (glucose-dependent insulinotropic polypeptide) agonism
Interestingly, GLP-1R residues, such as L 141 , Y 145 , K 197 , L 201 , K 202 , Y 205 , R 299 , L 384 , E 387 , and L 388 , which interacts with these agonists also establish contacts with SR18
