Your complete guide to using Wegovy for weight loss

Wegovy is an exciting development in the field of weight management and is available in the UK.

What is Wegovy?

Wegovy is a once-weekly injectable medication containing semaglutide, an active ingredient that is commonly used to stabilise blood sugar levels and aid weight loss. It has been studied and trialled as a weight management drug and, when used alongside a calorie deficit and exercise routine, it can be an effective treatment for weight loss.

Wegovy has recently been approved for use in the UK and was made available for the UK market on September 4, 2023. It is suitable for adults with a body mass index (BMI) of 30+, or 27+ with weight-related health issues, such as diabetes, high blood pressure, PCOS, asthma or high cholesterol.

You can access Wegovy via Juniper's Weight Reset Programme.

How does Wegovy work?

When we eat, our bodies release a hormone called glucagon-like peptide 1 (otherwise known as GLP-1), which releases insulin, helps regulate blood sugar levels and induces satiety. In other words, it lets our brains know that we're full and that it's time to stop eating.

Semaglutide, the main ingredient present in the Wegovy weight loss injections, is able to mimic this natural hormone, helping to regulate your appetite and slow down your 'gastric mobility'.

This is why Wegovy is such an effective medication for weight management [1]. But, what exactly does it mean?

In short, it means that the food you eat stays in your stomach for longer, so you don't experience hunger as often as usual and are less likely to consume snacks and larger meals. As a result, you consume fewer calories and, ultimately, reduce your body weight.

How effective is Wegovy for weight loss?

As a higher-dose injection of semaglutide, Wegovy has been shown in clinical trials to be more effective for weight loss than some of its alternatives [2].

A study from 2021 looked at 1,961 obese and overweight adults who were randomly assigned Wegovy injections or a placebo [2]. The results speak for themselves: after 68 weeks, those taking Wegovy lost an average of 15.3 kg, whereas the placebo group lost an average of 2.6 kg.

It's important to mention that the participants also implemented lifestyle changes, particularly in their diet and exercise habits, which helped enhance the impact of Wegovy as a weight loss drug.

What are the benefits of Wegovy?

The biggest benefit of Wegovy lies in its ability to deliver sustained weight loss. Since you feel more satisfied between meals, you experience fewer cravings and are able to adopt a healthier diet that you can stick to.

Additionally, although it is not technically an antidiabetic drug, Wegovy can help control blood sugar levels and reduce the risk of type 2 diabetes in overweight or obese people [3].

What Wegovy dose should I take?

The recommended dose for Wegovy is 2.4mg in weekly injections.

However, it is common for clinicians to prescribe Wegovy at a lower dose to start with, and gradually increase it over time. This helps your body get used to the medication which, in turn, minimises the risk of side effects (which we'll get to shortly).

Wegovy vs Saxenda

Although Wegovy and Saxenda are both GLP-1 receptor agonists — meaning they work in similar ways to minimise your appetite — there is one fundamental difference between the weight loss treatments: their active ingredients.

Instead of semaglutide, Saxenda contains liraglutide, a prescription medication that also mimics the naturally occurring hormone, GLP-1.

Due to this difference in active ingredients, Saxenda is a daily injection, rather than weekly, which for some people can lead to more (yet less intense) side effects.

Wegovy vs Ozempic

Wegovy and Ozempic are similar in many ways as both are injectable medications containing semaglutide, however, there are a couple of key disparities between these medications.

For starters, each has different medical licenses. Wegovy was originally trialled as a treatment for obesity, and is available via prescription for weight management and to treat obesity whereas Ozempic islicensed to treat diabetes.

Additionally, Ozempic and Wegovy are administered in different dosages. The first is currently supplied in dosages up to 1mg per week, while the second can go up to 2.4mg per week.

What are the side effects of Wegovy?

Different people respond to weight loss drugs differently and as is the case with most medications, there are side effects associated with Wegovy.

The good news is that these are typically mild and tend to disappear a few weeks into the treatment.

Some of the potential side effects of Wegovy include:

• Nausea
• Vomiting
• Constipation
• Diarrhoea
• Abdominal pain
• Bloating and gas buildup
• Fatigue
• Gastroenteritis
• Gastroesophageal reflux disease

Often, these symptoms occur as your body is adjusting to the drug (hence why they're usually temporary) and there are a few simple ways you can manage them:

• Drink plenty of water throughout the day
• Avoid high-sugar and high-fat foods
• Eat small meals regularly
• Maintain a healthy level of physical activity by going on regular walks
• If needed, take painkillers to relieve discomfort

In extreme and very rare cases, Wegovy can result in an allergic reaction with symptoms like swelling of the face and difficulty breathing and swallowing, in which case you should seek immediate emergency medical help.

If you experience ongoing side effects after taking Wegovy, it's important that you speak to your prescriber. They will help you understand why your body is responding this way to the medication and how you can best address the symptoms.

How do I get Wegovy in the UK?

In 2022, the National Institute of Health and Care Excellence (NICE) approved and recommended Wegovy as a safe option for weight management in the UK [4].

As a result,, you can access Wegovy through a prescription in person or via telehealth clinics online. Juniper uses Wegovy as part of its Weight Reset Programme, which also includes dietitian-led coaching and support as well as 1:1 health tracking and access to a private community of women on the same journey as you.

Is Wegovy by prescription only?

Yes, Wegovy is a prescription-only medication.

This means you can't get it over the counter and instead, have to get it prescribed by an authorised healthcare professional.
