My doctor explained that both Metformin and Ozempic are used to manage type 2 diabetes, but they have distinct mechanisms that can synergistically aid in weight loss. Metformin primarily works by decreasing glucose production by the liver and improving the body's sensitivity to insulin, which can lead to modest weight loss. Ozempic, a GLP-1 receptor agonist, works by stimulating insulin release, suppressing glucagon, slowing gastric emptying, and promoting a feeling of fullness. When prescribed together, their combined effects can lead to more significant blood sugar control and weight reduction than either drug alone, particularly for patients with co-morbidities. This is a clinician-guided decision, not a self-initiated one.
