Our approach
Backed by science
Patients can finally take control and reduce their risk of several obesity-related health conditions. For us, these weight loss programmes are as much about reducing the risk of type 2 diabetes and weight related cancer as they are about losing weight.

You and your coach will create a personalised plan for sustainable weight loss, with the potential to lose on average 16% of your body weight, while ensuring you maintain your new healthy habits.*

What is Wegovy 7.2mg?
Wegovy 7.2mg is the newest and highest strength in the Wegovy range. It's designed for patients who have already reached and tolerated the 2.4mg dose and are ready to take the next step in their treatment.
- How does it work? Like other Wegovy doses, the 7.2mg pen contains semaglutide, which helps regulate appetite, slow digestion, and increase feelings of fullness. This higher dose can enhance these effects and support greater weight loss results.
- What results can I expect? Clinical studies show that patients using Wegovy 7.2 mg, alongside healthy lifestyle changes, achieved up to 20.7% weight loss over 72 weeks. An improvement on the results seen with lower doses.
- Who is it suitable for? The 7.2mg dose is for those who have tolerated the 2.4 mg maintenance dose well and may benefit from a higher strength. Your prescriber will confirm whether it's appropriate for your individual treatment plan.
Can I switch from Mounjaro to Wegovy?
Yes, switching from Mounjaro to Wegovy may be possible, but this will be assessed on a case-by-case basis by your prescribing clinician. Before making the decision to switch, it's important to consider the following:
- Washout period required You'll need to wait at least 7 days after your last Mounjaro dose.
- Starting dose If you've had no side effects and your gap between doses is less than 3 weeks, you may be eligible to start:

- Your weight loss goals Depending on how much weight you are aiming to lose; it may be more beneficial to continue with Mounjaro rather than switch.
If you've experienced side effects, a longer washout period or lower starting dose may be required.
Please note: The final decision will always be made by our clinical team based on your consultation responses. Requesting a specific dose does not guarantee it will be prescribed.
Benefits of Wegovy
- Works by targeting GLP-1 receptors, similar to Mounjaro.
- Clinical trials have shown an average weight loss of 16%, with many patients achieving more.
- Licensed for weight maintenance, meaning it is safe to continue even after you reach your goal weight.
- Long-term studies show patients can maintain their weight loss when staying on treatment.
- Proven cardiovascular benefits, including a significant reduction in the risk of heart attack or stroke.
Switching to Wegovy may be right for some patients and not for others. If you are considering a switch, speak to your prescribing clinician so you can decide together what is in your best interest.
What is BMI?
Body Mass Index (BMI) is a calculation based on your height (m) and weight (kg) that is used to determine if your weight is healthy. Your BMI will be calculated as a number which represents your height to weight ratio i.e. 32kg/m2.

BMIs are shown in ranges as follows:
- An ideal BMI is between 18.5 and 24.9kg/m2
- Between 25 and 29.9kg/m2 – you're considered overweight
- Between 30 and 39.9kg/m2 – you're considered to be in the obese range
As well as measuring your BMI, healthcare professionals may take other factors into account to assess if you're a healthy weight.
Which treatment is best for me?
A healthy diet and exercise are the best way to lose weight. However, you may benefit from also taking weight loss medication. A consultation with one of our UK registered doctors will identify if medication is right for you and, if so, what the right treatment plan is.
Why haven't I been able to lose weight on my own?
Losing weight is hard and takes time, so don't give up. It is important to get the right approach for you, and that you are happy with the progress you are making. As you lose weight, we will review your treatment plan and medication to help you achieve your weight loss goals.
Can I exercise when taking weight loss medication?
Of course. Exercise and healthy eating should be part of a weight loss programme alongside any prescribed medication. As well as helping you to burn extra calories, it will also improve your general health and wellbeing, helping you maintain your weight once you have reached your goal and stopped treatment. Don't do too much too soon, ease into it depending on your current level of activity.
Should I adjust my diet whilst taking my weight loss medication?
You will need to review your diet while taking your weight loss medication. Some medications require a reduced-fat or calorie-controlled diet to minimise side effects or meet your weight loss goals. It is important to ensure the food you eat is balanced so that you are not missing out on any essential nutrients. Eating a balanced diet is a lifestyle change that you should continue even after achieving your weight loss goal.
Will my treatment go on my medical record?
We ask you to provide us with your GP's details and we encourage you to speak to them about your weight loss goals, however we do not share your treatment plan with them unless you agree for us to do so.
How long should it take to lose weight?
This very much depends on how much weight you need to lose to reach your goal, and other measures you take towards a healthier lifestyle such as diet and exercise. In general, slow and steady weight loss is preferable to trying to lose a large amount of weight quickly. It is recommended to aim to lose 1-2lb per week.
Will the weight come back after the treatment is stopped?
Your treatment plan will help you to achieve your weight loss goal, but you should adopt a healthier lifestyle, which includes a balanced diet and exercise, to help you maintain a healthy weight even after the medication has stopped.
