In recent years, semaglutide injections have gained attention as a powerful tool for weight loss, thanks to their ability to reduce appetite and support long-term weight management. But if you’re based in the UK, you may be wondering: how does Ozempic work for weight loss, and what is the difference between Ozempic and Wegovy?

At Eltham Pharmacy, we support patients looking for safe, medically supervised weight loss options. With increasing demand for injectable weight loss treatments, we’re here to explain how semaglutide works, which product is available in the UK, and what to expect from your weight loss journey with professional guidance.

What Is Semaglutide?

Semaglutide is a medication that mimics a naturally occurring hormone in the body called GLP-1 (glucagon-like peptide-1). This hormone plays a key role in regulating blood sugar and appetite. By mimicking GLP-1, semaglutide slows down stomach emptying, helps you feel fuller for longer, and reduces food cravings—all of which contribute to reduced calorie intake and gradual fat loss.

Semaglutide was originally developed as a treatment for type 2 diabetes under the brand name Ozempic. However, higher doses of semaglutide have now been licensed and branded as Wegovy, specifically for weight loss in people who are overweight or obese.

Ozempic vs Wegovy: What’s the Difference?

Though both medications contain the same active ingredient (semaglutide), Ozempic and Wegovy are licensed for different uses and have distinct dosing regimens.

Ozempic:

• –> Licensed in the UK for type 2 diabetes, not for weight loss

• –> Typically prescribed in lower doses (0.25 mg to 1 mg once a week)

• –> Sometimes used off-label in other countries (like the US) for weight loss, but not approved for weight loss in the UK

Wegovy:

• –> Licensed and approved in the UK specifically for weight loss

• –> Contains higher doses of semaglutide (up to 2.4 mg once a week)

• –> Prescribed to adults with a BMI of 30 or more, or 27 or more with a weight-related condition (e.g. hypertension, PCOS, sleep apnoea)

• –> Supplied alongside a structured weight loss programme, often through pharmacies or weight loss clinics

So, when UK patients ask, “How does Ozempic work for weight loss?”, the answer is: it’s not the approved product here.

Wegovy is the version of semaglutide licensed for weight loss in the UK.

How Does Ozempic (Semaglutide) Work for Weight Loss?

Regardless of the brand, semaglutide works by:

• –> Slowing down digestion, helping you feel full after smaller meals

• –> Reducing the brain’s hunger signals and cravings

• –> Supporting more stable blood sugar levels and reducing insulin resistance

This combined effect can lead to significant reductions in body weight over time. In clinical trials, patients using Wegovy lost around 15% of their body weight on average, especially when paired with dietary support and increased physical activity.

It’s important to note that semaglutide doesn’t cause weight loss by speeding up your metabolism. It works by helping you naturally eat less, without the constant struggle with hunger that many people face on traditional diets.
