Our UK-licensed prescribers review your consultation within 24 hours to check treatment suitability.
If approved, your prescription weight loss medication is dispensed via UK-registered pharmacy and delivered safely to you.
Prescription weight loss injections are designed to mimic the action of the naturally occurring hormone glucagon-like peptide-1 (GLP-1), which plays a key role in regulating appetite, gastric emptying, and blood glucose levels, helping you manage your weight safely and effectively.
These medications act on appetite-control centres within the hypothalamus in the brain, reducing hunger and the neural activity that drives food thoughts, making it easier to focus on balanced meals rather than cravings.
By slowing gastric emptying, they help you feel full for longer periods after eating naturally, reducing portion sizes and overall calorie intake.
The medication supports stable blood sugar levels after meals, preventing sharp spikes and drops that can trigger hunger and sugar cravings.
When combined with mindful eating, regular movement, and professional clinical guidance, these treatments can help you build sustainable habits that protect your long-term health.
Weight loss can significantly improve your health and wellbeing, leading to a longer, more active life. It’s important to remember that every person’s journey is different, and achieving weight loss safely requires professional guidance, a balanced approach, and realistic expectations.
Losing excess weight is linked to lower blood pressure and cholesterol levels, which reduces the risk of heart disease and stroke.
Losing weight improves your body's ability to use insulin, helping to stabilise blood sugar levels and potentially reduce or eliminate the need for medication.
By achieving and maintaining a healthy weight, you significantly lower your chances of developing type 2 diabetes, high blood pressure, sleep apnea, and even certain types of cancer, improving your long-term health outlook.
Losing weight can increase your flexibility and make it easier to move freely, allowing you to take part in activities with more comfort and less effort.
Obesity is a complex health condition characterised by excess weight gain that shows as a high proportion of body fat. In the UK, obesity is estimated to affect around 1 in every 4 adults and 1 in every 5 children aged 10 to 11. It affects the way the body functions daily.
When excess weight begins to put pressure on your heart, joints, or blood sugar levels, it can increase the risk of long-term conditions such as:
Other problems that may interfere with your daily life include:
Understanding obesity is the first step toward a healthy lifestyle. With the right medical guidance, small and safe steps can lead to long-term health improvements and renewed confidence in your well-being.
Weight gain does not have a single cause. Many small factors collectively contribute to it, including:
One of the most common causes of weight gain is an unbalanced diet. Everyone’s nutritional needs are different and depend on factors such as age, sex, weight, and existing health conditions. A diet that doesn’t match your body’s needs can lead to excess calorie intake and fat storage over time.
To support healthy weight management, try to limit foods and drinks that are high in fat, sugar, and calories, such as:
It is possible to have a high BMI without being obese. For example, people with high muscle mass may have a higher BMI despite having a lower level of body fat. But for most people, BMI is a useful indication of whether or not they are a healthy weight.
Certain medical conditions can also contribute to weight gain by affecting metabolism, hormones, or energy balance.
Common examples include:
Modern life often encourages sitting for long periods at work, during travel, or while relaxing.
A sedentary lifestyle, where you spend most of the day sitting or lying down with minimal physical activity, can gradually lead to weight gain as your body stores unused calories as fat.
Incorporating more movement into your day, like walking, stretching, taking the stairs, or light exercise, helps boost metabolism and supports weight control in a sustainable way.
Some prescription or hormonal medications can cause weight gain as a side effect. These may influence appetite, fluid retention, or how your body stores fat.
Common examples include:
These factors influence how your body stores fat and regulates appetite. Recognising these causes can help you find realistic ways to manage your weight.
You may consider losing weight if it begins to affect your health, mobility, or confidence in daily life.
Medical professionals often use a tool called BMI (Body Mass Index) to understand whether a person’s weight is within a healthy range.
If your BMI is ≥ 30, or ≥ 27 with weight-related health problems you must consider losing weight.
Your BMI is a quick calculation that compares your weight and height to estimate body fat levels.
You can use a simple online BMI calculator by entering your weight (in kilograms) and height (in metres).
Note that BMI is a starting point, not a diagnosis. Learn more about treatment for obesity.
Safe weight loss is never rapid. It is a gradual progress. Healthy weight loss can be achieved by eating balanced meals, increasing physical activity, getting enough sleep, and managing stress, all of which contribute to steady, sustainable results.
For some people, lifestyle changes alone may not be enough to reach or maintain a healthy weight. In those cases, people may need to get additional medical support, such as prescription weight loss treatments, to complement diet and lifestyle.
Long term results depend on habits that support your health every day. This includes choosing nutritious foods, staying active in ways you enjoy, drinking enough water, and limiting high-sugar or processed foods.
Sustainable change also means building a routine that feels achievable, like walking regularly, getting good sleep, and learning to listen to hunger and fullness cues. Consistency, not perfection, is what helps you maintain progress safely over time.
Weight loss treatments are designed to support healthy lifestyle changes rather than replace them. These treatments help influence biological processes linked to hunger, appetite control and metabolism to support long-term weight management when used under clinical supervision.
Before starting treatment, you will complete an online consultation form that reviews your overall health, medical history and weight-related factors. Our UK-licensed prescribers assess your BMI, existing conditions and current medicines to determine whether a suitable treatment option is available. Not everyone will meet the eligibility criteria, and in some cases, lifestyle changes alone may be recommended.
Our clinic provides access to prescription weight loss injections and weight loss pills, including Mounjaro (tirzepatide), Wegovy (semaglutide), Wegovy pill (semaglutide) and Foundayo (orforglipron). We previously provided Saxenda (liraglutide) for weight management, but due to limited availability in the UK, many patients have moved to alternative options such as Wegovy or Mounjaro following clinical assessment.
Weight loss injections are prescription treatments that support weight management by targeting hormonal pathways involved in appetite regulation and hunger control. They can help increase feelings of fullness and support reduced calorie intake.
The weight loss injections available through our service include:
Mounjaro is a dual-action treatment that targets both GLP-1 and GIP pathways, which are involved in appetite control and metabolism. Wegovy Injection and Saxenda work through GLP-1 pathways to support appetite regulation and weight management.
Suitability for weight loss injections depends on your individual health circumstances and treatment requirements. This usually includes:
Eligibility can vary depending on the specific medicine, your medical history and current health. Providing accurate information during your consultation helps a clinician determine whether a treatment is suitable and provide appropriate guidance.
Weight loss pills are prescription oral treatments that provide a needle-free option for eligible patients who prefer tablets over injections. They are taken as part of a medically supported weight management plan alongside a balanced diet and regular physical activity.
The weight loss pill options available through our service include:
Both treatments work through GLP-1 pathways involved in appetite regulation and feelings of fullness. Wegovy pill contains semaglutide, while Foundayo contains orforglipron. Although they support weight management through similar pathways, they have different dosing schedules, administration instructions and clinical guidance.
Suitability depends on your health circumstances, current medicines and weight-related factors. Our clinician will review your information to confirm whether this option is appropriate and safe for you.
Our clinicians provide ongoing support with treatment guidance, managing potential side effects, nutrition advice and sustainable weight management strategies throughout your treatment journey.
Eligibility can vary depending on the specific medicine, your medical history and current health. Providing accurate information during your consultation helps a clinician determine whether a treatment is suitable and provide appropriate guidance.

Important Note: *Weight loss outcomes from clinical studies should be interpreted separately. Each treatment has been evaluated under different trial conditions, participant groups and dosing schedules. Individual results may vary depending on personal response and other factors.
Weight loss injections work by mimicking hormones involved in appetite control and digestion. GLP-1-based treatments help increase fullness, reduce hunger signals and support healthier food intake.
Wegovy Injection and Saxenda activate GLP-1 receptors to support appetite control and reduce food intake. Mounjaro works through a dual mechanism by targeting both GLP-1 and GIP pathways, which are involved in appetite regulation and metabolism.
By helping regulate hunger signals, these treatments can make it easier to follow a reduced-calorie diet and support weight management alongside regular physical activity and clinical guidance.
Mounjaro and Wegovy Injection are taken once weekly, while Saxenda is taken once daily. Treatment doses are gradually adjusted according to medical guidance to improve tolerability and support safe use.
Weight loss pills are oral treatments that provide a needle-free option for eligible patients who prefer tablets. They work by targeting pathways involved in appetite regulation, hunger control and metabolic processes.
Wegovy pill contains semaglutide, a GLP-1 receptor agonist that helps increase feelings of fullness and reduce appetite. Foundayo contains orforglipron, an oral GLP-1 receptor agonist designed to support appetite regulation without injection requirements.
Unlike injectable treatments, weight loss pills are taken orally. Wegovy pill require specific fasting instructions before taking the tablet, while Foundayo can be taken once daily with or without food.
Both treatments should be used alongside a balanced diet, regular physical activity and ongoing clinical support. Individual results vary depending on treatment response, adherence and lifestyle factors.
Eligibility for weight loss treatments depends on factors such as your BMI, medical history, existing health conditions and overall suitability. Both weight loss injections and weight loss pills require a clinical assessment before they can be prescribed.
These treatments may be suitable for adults who:
Eligibility requirements can vary between treatments, including Mounjaro, Wegovy Injection, Saxenda, Wegovy pill and Foundayo. These medicines are not suitable for everyone and should not be used during pregnancy, while trying to conceive or during breastfeeding.
A clinician will review your online consultation form, including your health history, current medicines and treatment suitability. They will determine whether a weight loss injection or weight loss pill is appropriate and safe for you.
Weight loss injections and weight loss pills can cause side effects, although these vary depending on the medicine, dose and individual response. Digestive symptoms are among the most commonly reported, especially when starting treatment or increasing the dose.
Common side effects may include:
Some treatments may also cause specific side effects. For example, injectable medicines can cause reactions at the injection site, while low blood sugar may occur when certain treatments are used alongside diabetes medicines such as insulin or sulfonylureas.
Side effects can differ between Mounjaro, Wegovy Injection, Saxenda, Wegovy pill and Foundayo. Always follow the patient information leaflet provided with your medicine and speak with a healthcare professional if you experience persistent, severe or concerning symptoms.
Yes, changing from one weight loss treatment to another may be an option if your current medicine is no longer the most suitable choice for your needs. However, weight loss treatments are not directly interchangeable. A clinician will review your current medication, dose, medical history and treatment progress before recommending a switch.
If a change is approved, our clinician will provide guidance on when to stop your current treatment and when to begin the new one. The recommended starting dose and timing between treatments will depend on your current medicine, treatment history and individual health circumstances.
Switching from Mounjaro to Wegovy may be considered if your treatment needs change, you experience side effects, have concerns about your current medicine or another option is considered more suitable following a clinical review.
Although both are weekly weight loss injections, they contain different active ingredients and work through different pathways. Mounjaro contains tirzepatide, which targets both GLP-1 and GIP receptors, while Wegovy contains semaglutide, which targets GLP-1 receptors.
If you request to switch, a clinician will assess your medical history, current Mounjaro dose and suitability for Wegovy. If approved, they will advise which Wegovy dose is appropriate and when you should begin treatment after your final Mounjaro injection.
Switching from Wegovy to Mounjaro may be possible if Mounjaro is considered a suitable alternative after a clinical assessment. Your current Wegovy dose, response to treatment, medical history and any side effects will be reviewed before a change is recommended.
Wegovy contains semaglutide and works through GLP-1 receptors, while Mounjaro contains tirzepatide and targets both GLP-1 and GIP pathways. If the switch is approved, our clinician will advise the appropriate Mounjaro starting dose and when to begin treatment.
Your Mounjaro dose may then be increased gradually according to the recommended schedule and how your body responds to treatment.
Switching from Mounjaro to Saxenda may be considered if you are experiencing tolerability issues, prefer a daily injection schedule or our clinician believes another treatment may be more suitable. Mounjaro contains tirzepatide and works by targeting both GLP-1 and GIP pathways, while Saxenda contains liraglutide and acts through GLP-1 receptors.
A clinician will review your current Mounjaro dose, medical history and treatment response before approving a switch. If suitable, they will advise when to stop Mounjaro and when to begin Saxenda. Saxenda is usually started at a lower dose and increased gradually to help your body adjust.
Switching from Saxenda to Mounjaro may be an option if you are not achieving your desired results, experience difficulties with your current treatment or would prefer a weekly injection instead of a daily one.
Saxenda and Mounjaro contain different active ingredients and follow different dosing schedules, so they cannot be switched using a direct dose conversion. A clinician will assess your current Saxenda dose, health information and treatment goals before recommending the appropriate Mounjaro starting dose and transition plan.
Switching from a weight loss injection to Wegovy Pill may be possible after a clinical assessment. This can provide a needle-free alternative for people who prefer taking a daily tablet instead of continuing with injections.
If you are using Wegovy Injection at the maintenance dose, our clinician may advise whether switching to Wegovy Pill is appropriate and when treatment should begin after your final injection.
For people using other injection treatments such as Mounjaro or Saxenda, there is no direct dose-for-dose conversion. Our clinician will consider your current medication, dose, response to treatment and medical history before recommending the suitable Wegovy Pill dose and timing.
Switching from Wegovy Pill to Foundayo may be possible if a clinician confirms that this change is suitable for your health needs. Wegovy Pill contains semaglutide, while Foundayo contains orforglipron. Although both work through GLP-1 pathways, they are separate treatments with different dosing schedules and usage instructions.
Foundayo may be an option for people who prefer a daily tablet with more flexible administration, as it can be taken with or without food. Our clinician will review your current Wegovy Pill dose, response to treatment, any side effects and the timing of your last dose before advising how to start Foundayo.
Switching from a weight loss injection to Foundayo may be considered following a clinical assessment. This may include treatments such as Mounjaro, Wegovy Injection or Saxenda. Foundayo is a once-daily oral GLP-1 treatment that provides a needle-free option for eligible patients who prefer tablets over injections.
Moving from an injection to Foundayo is not a direct dose-for-dose change. Injectable treatments and Foundayo have different active ingredients, dosing schedules and clinical evidence. Our clinician will assess your current medicine, dose, treatment response and medical history before recommending whether a switch is appropriate.
If a switch is approved, our clinician will advise when to stop your current injection and when to begin Foundayo. The recommended starting dose will depend on your previous treatment and individual circumstances to help ensure a safe transition.
Choosing the most suitable weight loss treatment depends on your individual health profile, including your BMI, medical history, current medicines, lifestyle and treatment preferences. Weight loss injections and weight loss pills offer different options, and a clinician will assess your circumstances before recommending a suitable treatment.
Weight loss injections may suit people who prefer a weekly or daily treatment using an injection pen and are comfortable with self-administration. Options such as Mounjaro, Wegovy Injection and Saxenda are prescribed based on individual suitability and clinical needs.
Weight loss pills may appeal to people who prefer a needle-free option and are comfortable following a daily tablet routine. Wegovy pill and Foundayo provide oral treatment options for eligible patients who prefer tablets over injections.
Choosing a treatment depends on factors such as your BMI, medical history, current medicines, previous treatments and personal preferences. A UK-licensed clinician will review your circumstances and recommend an option that is suitable for your health needs.
Successful weight management involves more than losing weight. The aim is to achieve sustainable progress and maintain a healthier weight through long-term lifestyle changes and appropriate clinical support.
After starting or completing a weight loss treatment plan, continuing healthy habits can help maintain your results. A balanced diet, regular physical activity, good sleep and stress management all contribute to long-term weight management.
Our clinician may review your progress over time and advise whether continuing medication, adjusting your treatment plan or using additional support may be appropriate for your needs.
Focus on realistic changes that fit your routine, such as increasing daily movement, choosing nutritious meals with whole foods, and maintaining healthy habits so you can continue long term. Avoid extreme diets or short-term approaches, as sustainable progress is built through consistent choices.
Weight loss injections and weight loss pills should only be obtained through a regulated healthcare provider following a clinician-approved prescription.
