What Are GLP-1 Weight Loss Injections and How Do They Work?

What Are GLP-1 Weight Loss Injections and How Do They Work? Introduction Weight management is a growing concern for many adults, particularly when traditional methods like diet and exercise don’t deliver the desired results. For those looking for a medically guided alternative, GLP-1 injections offer a powerful and clinically reviewed option. These weight loss injections target the hormones that regulate appetite and digestion, helping support sustainable weight reduction under medical supervision. In this article, we’ll explain what GLP-1 treatments are, how they work, and why they’re among the most effective tools available for weight management today. What Are GLP-1 Weight Loss Injections? GLP-1 stands for glucagon-like peptide-1, a naturally occurring hormone released by the gut after eating. It plays a critical role in regulating appetite, insulin production, and digestion. GLP-1 receptor agonists are medications that mimic this hormone, helping to reduce hunger and improve blood sugar control. GLP-1 injections are often referred to as appetite suppressants, but their benefits go beyond that. By influencing the body’s hormonal response to food, they help patients feel fuller, reduce calorie intake, and support long-term weight loss. In the UK, the most widely used GLP-1 injections include: Wegovy (semaglutide) – a once-weekly injection Mounjaro (tirzepatide) – a once-weekly dual-action injection Both are available privately through MediClick Pharmacy following an online consultation with a UK-registered prescriber. How GLP-1 Injections Aid Weight Loss GLP-1 receptor agonists work in three key ways: Appetite Regulation –These injections act on areas of the brain that control hunger and satiety, making you feel full more quickly and reducing the urge to snack. Slowing Digestion –By delaying gastric emptying, food stays in your stomach longer, leading to increased satiety and smaller portion sizes.    3. Blood Sugar & Metabolic Support – GLP-1 injections enhance insulin response and help regulate blood glucose levels, which can be beneficial for patients with type 2 diabetes or insulin resistance. Who Should Consider GLP-1 Injections? GLP-1 treatments such as Wegovy and Mounjaro are prescribed for: Adults with a BMI of 30 or more (classified as obese) Adults with a BMI of 27+ with a related health condition such as high blood pressure, high cholesterol, or prediabetes For individuals who’ve struggled with traditional weight loss methods, these prescription treatments offer a structured and medically supported alternative. What Results Can You Expect? Clinical trials have demonstrated the effectiveness of GLP-1 weight loss injections: Mounjaro (tirzepatide) has shown weight reductions of up to 22.5% over 72 weeks. Wegovy (semaglutide) users lost approximately 15% of body weight over 68 weeks. These results are significantly higher than those typically achieved through diet and exercise alone, particularly when supported by behavioural changes. How GLP-1 Injections Compare to Other Methods Unlike over-the-counter supplements or fad diets, GLP-1 injections target the body’s natural hormone systems. This approach helps patients manage hunger in a sustainable way, making them more effective for long-term results. While other methods may offer quick fixes, GLP-1 therapies are designed for clinically guided, gradual weight reduction with ongoing support. Side Effects and Considerations As with any prescription treatment, GLP-1 injections may cause side effects. The most common include: Mild nausea Diarrhoea or constipation Fatigue Stomach discomfort These effects are often temporary and resolve as your body adjusts.
