The Truth About Ozempic and Wegovy: How These Medications Work for Weight Loss

You’ve probably heard about Ozempic and Wegovy—they’ve been making headlines as game-changers for weight loss. But what exactly are they, and how do they work?

At Ready Health Private Medical Clinic in Standish, we get a lot of questions about these medications, and we’re here to explain them in a clear, friendly way.

What Are Ozempic and Wegovy?

Both Ozempic and Wegovy contain a medication called semaglutide. It’s a type of drug called a GLP-1 receptor agonist. It helps regulate appetite and how your body processes sugar.

• Ozempic was originally developed to help people with type 2 diabetes.
• Wegovy is specifically licensed for weight loss.

Both are given as once-weekly injections.

How Do They Help With Weight Loss?

Semaglutide works by mimicking a hormone that tells your brain you’re full. This means:

• You feel full faster
• You stay full longer
• You have fewer cravings

All of this makes it easier to eat less without feeling miserable.

What’s the Difference Between Ozempic and Wegovy?

• Ozempic is typically prescribed off-label for weight loss when Wegovy is not available.
• Wegovy is the only one approved in the UK for weight loss.

Both are effective, but Wegovy is available in higher doses, which may lead to greater weight loss.

Are There Side Effects?

Like all medications, these can cause side effects—most commonly:

• Nausea
• Constipation or diarrhoea
• Loss of appetite

These usually improve as your body gets used to the medication.

Are They Right for Me?

You may be eligible if:

• Your BMI is 30 or more
• Or your BMI is 27+ with weight-related conditions (like high blood pressure or sleep apnoea)

Our team at Ready Health can assess your health and discuss whether these treatments are safe and suitable for you.

A Word of Caution

These medications work best with lifestyle changes—not instead of them. They're tools, not magic fixes. But when used properly, they can help you achieve lasting results.
