How Mounjaro Helps In Weight Loss

Mounjaro is a medicine from the drug class Antidiabetics, Glucose-dependent Insulinotropic Polypeptides also known as Gastric Inhibitory Polypeptide (GIP) & Glucagon-Like Peptide-1 (GLP-1). Glucose-dependent Insulinotropic Polypeptide is a natural hormone produced by the small intestine after you eat food. GIP hormone’s main function is to promote the release of insulin in the bloodstream to control blood sugar levels. Glucagon-Like Peptide-1 receptor agonist is also released in response to our food intake. The combination of these both GIP & GLP-1 not only helps in controlling blood sugar levels but also helps in reducing food intake and burning more calories. Thus, Mounjaro helps in weight loss.

Mounjaro Mechanism Of Action

GIP & GLP-1 are both hormones that belong to incretins. Incretins are a group of hormones that helps in controlling and lowering blood glucose levels. These incretins hormones are released in our bloodstream after food intake. Releasing these hormones is a glucose-dependent mechanism that enhances the production of insulin secreted by the group of pancreatic cells which is known as the Islets Of Langerhans in the pancreas.

Glucose-dependent Insulinotropic Polypeptides & Glucagon-Like Peptide-1 together secrets around 70% of insulin after food intake. Treating Type-2 diabetes is about controlling and lowering blood sugar levels. GIP & GLP-1 helps in the same functioning of lowering blood sugar levels. And Mounjaro is a single molecule that activates the body’s receptors for GIP & GLP-1 hormones.

The results of Phase-1 of the Mechanism Of Action study were presented on 6th June 2022. These were the results of 28-week studies. The trials were conducted to evaluate the effect of Mounjaro 15 mg compared to placebo and to injectable semaglutide 1 mg. The results of this Mechanism Of Action study are given below.
