Metformin
A diabetes medication that also supports weight loss by improving insulin sensitivity and reducing appetite.
Patient-Friendly Explanation
Metformin is a widely prescribed medication primarily used to treat type 2 diabetes by lowering blood sugar levels. It also has a modest weight loss effect — many patients lose 2-3 kg — because it reduces appetite and improves how the body responds to insulin, making it easier to burn stored fat.
Clinical Definition
Metformin is a biguanide antihyperglycaemic agent that reduces hepatic gluconeogenesis, increases peripheral insulin sensitivity, and decreases intestinal glucose absorption. Its weight-modulating effects are thought to stem from AMPK activation, altered gut microbiota, and increased GLP-1 secretion. While not primarily a weight loss drug, meta-analyses show a mean weight reduction of 2.1 kg versus placebo in overweight individuals.
Why It Matters
Metformin is often the first-line medication for patients with insulin resistance or prediabetes who are struggling with weight. At NuLifeCare, Dr. Joseph Wang may prescribe metformin as part of a comprehensive weight management plan for patients who have difficulty losing weight due to underlying insulin resistance.
