Weight loss injections have become increasingly popular in the UK, offering new avenues for individuals struggling with weight management. High-profile weight loss drugs like Saxenda, Ozempic/Wegovy (both brands of Semaglutide), and Mounjaro (Tirzepatide) are attracting attention for their ability to aid weight loss when combined with a healthy lifestyle. However, the popularity of these medications has also led to a rise in unauthorised sellers, leading to serious health risks for those obtaining injections without clinical oversight or prescriptions.
This article explores the appeal of weight loss injections, the specific uses of Saxenda, Ozempic/Wegovy, and Mounjaro, the dangers of buying from unauthorised sources, and guidelines for safe, clinically-supervised use.
Why Are Weight Loss Injections So Popular?
Weight loss injections offer a promising option for those who have struggled to lose weight with traditional methods like diet and exercise. Medications like Saxenda, Ozempic/Wegovy, and Mounjaro belong to a group of drugs known as GLP-1 receptor agonists, which mimic the hormone GLP-1 to help control blood sugar levels and suppress appetite. These treatments support weight loss by reducing hunger, promoting satiety, and slowing gastric emptying.
The appeal lies not just in aesthetics; obesity is linked to serious health conditions, including type 2 diabetes, cardiovascular disease, and high blood pressure. For individuals at risk of these conditions, medically-supervised weight loss injections may offer significant health benefits.
However, these medications are not a universal solution, nor are they suitable for everyone. Careful medical supervision is necessary to maximise benefits and reduce risks, particularly for individuals with specific health conditions that may make them ineligible for these treatments.
A Guide to Popular Weight Loss Injections in the UK
Each of the leading weight loss injections currently available has unique characteristics, benefits, and uses:
Saxenda (Liraglutide)
How It Works: Saxenda is a GLP-1 receptor agonist that helps regulate appetite by impacting the areas of the brain that control hunger. It is injected daily and requires a gradual dosage increase over time.
Uses: Approved for weight management in individuals with a body mass index (BMI) of 30 or higher or those with a BMI of 27 or higher and at least one weight-related health condition (e.g., high blood pressure, type 2 diabetes).
Common Side Effects: Nausea, diarrhoea, constipation, and headaches. With medical supervision, dosages can be adjusted to help manage these effects.
Ozempic and Wegovy (Semaglutide)
How It Works: Both Ozempic and Wegovy contain the active ingredient Semaglutide, which mimics GLP-1 to reduce hunger and increase satiety. Ozempic is approved for type 2 diabetes, while Wegovy is approved specifically for weight management.
Uses: Wegovy is approved for weight management in adults with a BMI of 30 or more, or with a BMI of 27 or more if they have weight-related conditions. Ozempic is primarily used to treat type 2 diabetes, but it has been prescribed off-label for weight loss.
Administration: Injected once weekly, which is convenient for patients.
Common Side Effects: Nausea, vomiting, and gastrointestinal discomfort. Healthcare providers can offer guidance on managing these effects.
Mounjaro (Tirzepatide)
How It Works: Mounjaro, a newer option, is a dual-action medication that targets both GLP-1 and GIP (glucose-dependent insulinotropic polypeptide) receptors. This dual action has been shown to increase its effectiveness in reducing appetite and supporting weight loss.
Uses: Primarily developed for managing type 2 diabetes, but it has shown promising results in weight loss, especially for those who have not responded well to other treatments.
Administration: Injected weekly, similar to Ozempic and Wegovy.
Common Side Effects: Gastrointestinal symptoms such as nausea, diarrhoea, and potential risk of hypoglycaemia in those who also take other glucose-lowering drugs.
Each of these medications can be highly effective when used correctly, but it’s essential to consult with a healthcare provider to determine which, if any, is appropriate for you.
The Risks of Buying Weight Loss Injections Without Clinical Oversight
The popularity of these treatments has led to an increase in unauthorised sellers, including online marketplaces, social media, and non-medical beauty clinics, offering weight loss injections at discounted prices or without requiring a prescription. This trend poses significant risks:
Counterfeit and Unsafe Products
Medications purchased from unregulated sources are often counterfeit or substandard, lacking the necessary quality control to ensure safety and effectiveness. These products may contain harmful substances or improper doses of the active ingredients.
Incorrect Dosing and Administration
Weight loss injections require specific dosing, often starting low and gradually increasing. Without medical guidance, individuals may take incorrect doses, risking severe side effects such as nausea, vomiting, and hypoglycaemia. Self-administering injections without proper training can also lead to infection, injury, and other complications.
Lack of Screening for Medical Contraindications
Weight loss injections are not suitable for everyone. Individuals with certain conditions—such as a history of thyroid cancer, pancreatitis, or gastrointestinal diseases—may be at increased risk if they take GLP-1 receptor agonists. Without clinical screening, patients may unknowingly take these medications despite potential contraindications.
Increased Risk of Adverse Reactions
Under clinical supervision, side effects are closely monitored, and dosage adjustments are made as needed. Individuals buying from unauthorised sources lack this essential support, increasing the risk of severe side effects and complications.
Absence of Holistic Support for Weight Management
Successful, long-term weight loss is achieved with a holistic approach that includes diet and lifestyle changes. Medical providers offer guidance to help individuals make these changes. Without this support, individuals may regain the weight once they stop using injections, or they may be less likely to make sustainable lifestyle adjustments.
How to Use Weight Loss Injections Safely and Effectively
To ensure the safe and effective use of weight loss injections, follow these guidelines:
Consult with a Licensed Healthcare Provider
Seek advice from a healthcare provider to assess your health, determine if weight loss injections are suitable, and identify which medication best fits your needs. Licensed prescribers, such as GPs or pharmacists with prescribing qualifications, can develop a treatment plan that takes your medical history into account.
Only Use Medications Obtained with a Prescription
Prescription weight loss injections should only be sourced through registered pharmacies. Avoid products from unauthorised sellers, including those selling via social media and unregulated online marketplaces.
Regular Check-Ins with Your Healthcare Provider
Ongoing medical supervision is essential to monitor progress, adjust dosing, and manage side effects. Your healthcare provider can also offer guidance on dietary changes and physical activity, which are essential for maximising results and maintaining weight loss.
Be Cautious of Unregulated Providers
Ensure that your provider is registered, qualified, and experienced in administering weight loss treatments. Licensed professionals, such as prescriber-qualified pharmacists and GPs, are trained to provide safe care and to recognise and manage potential risks.
The Importance of Regulated Care and Clinical Oversight
While weight loss injections may offer an effective option for some, they should always be used as part of a comprehensive, medically supervised weight management program. The risks associated with unauthorised providers are too significant to ignore, as they involve potential exposure to counterfeit products, unsafe dosing, and lack of health monitoring.
Healthcare professionals, including registered pharmacists and licensed prescribers, are trained to ensure that treatments like Saxenda, Ozempic/Wegovy, and Mounjaro are used safely and appropriately. They can provide the essential guidance needed to ensure that patients achieve their goals without compromising their health.
Final Thoughts
The rise of weight loss injections in the UK reflects a demand for effective weight management solutions, but it also highlights the dangers of unauthorised providers offering unsafe, unregulated treatments. Buying injections without clinical oversight exposes individuals to counterfeit products, inadequate medical assessments, and unmonitored side effects, all of which can have severe consequences.
For those considering weight loss injections, the safest route is to seek advice from a licensed healthcare provider.
