Medical Weight Loss & Weight Management London | GLP-1 Injections & Mounjaro®
Medical Weight Management with Prescription GLP-1 & GIP Therapy in London
Medical Weight Management is a regulated obesity treatment service for patients with clinically significant excess body weight.
At London Professional Aesthetics, we provide clinician-led access to prescription weight loss injections, including GLP-1 receptor agonists and dual GLP-1/GIP therapies such as Mounjaro® (tirzepatide).
This weight loss service forms part of a structured treatment plan designed to support sustainable weight reduction under medical supervision. It is not intended for minor or purely cosmetic weight-loss goals.
All patients undergo an initial consultation to determine suitability and personalise their treatment pathway safely and appropriately.
What Are GLP-1 Weight Loss Injections?
GLP-1 receptor agonists are injectable medications that influence appetite regulation and glucose metabolism. These weight loss injections work by enhancing satiety, reducing appetite and supporting improved insulin sensitivity.
These medications were originally developed to improve blood sugar control in patients with type 2 diabetes. Clinical trials later demonstrated their effectiveness in supporting weight reduction in individuals with obesity.
Semaglutide-based therapies such as Wegovy® and Ozempic® act on GLP-1 receptors, while newer agents like Mounjaro® (tirzepatide) act on both GLP-1 and GIP pathways. This dual mechanism may enhance appetite regulation and fat loss in appropriately selected patients.
All prescribing is carried out in accordance with UK medical guidelines and regulatory standards.
Who Is Eligible for Medical Weight Management?
Prescription weight-loss treatment may be appropriate for adults who:
- Have a BMI ≥ 30
- Have a BMI ≥ 27 with obesity-related health problems
- Have struggled to reduce body weight despite structured lifestyle changes
- Have metabolic or cardiometabolic risk factor
A comprehensive initial consultation is required before any prescription is issued. This allows us to review medical history, current medications and potential contraindications before developing a personalised treatment plan.
This service is not appropriate for individuals seeking rapid “quick fixes.” It is designed to support a supervised weight loss journey grounded in safety and clinical oversight.
Clinical Assessment & Safety Screening
Before prescribing any weight loss injection, we conduct:
- Detailed medical history review
- BMI and risk assessment
- Medication and contraindication screening
- Blood testing where clinically indicated
- Discussion of realistic outcomes and expectations
GLP-1 and GLP-1/GIP therapies are not suitable for everyone. Particular care is taken in patients with endocrine conditions, thyroid history, pancreatitis risk or certain gastrointestinal disorders.
Prescriptions are issued only by qualified UK medical professionals, and patients are monitored regularly throughout treatment.
Common Side Effects
Common side effects may include nausea, bloating, constipation, reduced appetite and temporary gastrointestinal discomfort. These symptoms most commonly occur during dose escalation and often settle as the body adjusts to treatment.
Patients are carefully monitored to manage tolerability and ensure that treatment remains appropriate and safe. We always aim to treat at the lowest effective dose to help minimise side effects.
Your Personalised Treatment Plan
If suitable, your personalised treatment plan may combine prescription injection therapy with:
- Structured nutritional guidance
- Muscle-preserving physical activity
- Behavioural support
- Ongoing clinical monitoring
As a medical weight management clinic in London, our approach integrates medication within a broader weight management programme focused on sustainable weight loss. We support patients in reducing excess body weight while maintaining lean mass and progressing toward a healthy weight.
Medication is used as part of a comprehensive strategy rather than as a standalone solution.
For individuals who wish to explore underlying metabolic or hormonal drivers before considering medication, our Weight Management & Metabolic Reset Programme offers a structured diagnostic pathway. Patients experiencing broader endocrine symptoms may also benefit from our Hormonal Balance & Stress Resilience Programme.
How Is Mounjaro® Different from Wegovy® or Ozempic®?
Wegovy® and Ozempic® are semaglutide-based GLP-1 receptor agonists previously prescribed for weight management.
Mounjaro® (tirzepatide) activates both GLP-1 and GIP receptors, offering a dual-pathway approach that may enhance appetite regulation and metabolic response in appropriate patients.
Your clinician will determine which therapy, if any, is suitable based on your starting weight, overall health profile and treatment goals.
Costs
Medical Weight Management treatment starts from £220 per month.

Frequently Asked Questions
How much weight can I realistically lose with GLP-1 or GLP-1/GIP therapy?
Weight loss varies depending on your starting weight, metabolic profile, adherence to treatment and lifestyle changes. Clinical studies demonstrate meaningful weight reduction when GLP-1 receptor agonists or dual GLP-1/GIP therapies are used alongside structured lifestyle intervention.
During your initial consultation, your clinician will discuss realistic expectations based on your individual health profile.
Are GLP-1 weight loss injections safe?
GLP-1 and GLP-1/GIP medications are licensed prescription treatments and must be prescribed by qualified healthcare professionals. When used appropriately and monitored carefully, they are generally well tolerated.
Before treatment, we conduct a comprehensive medical assessment to review your medical history, medications and potential contraindications. Ongoing follow-up ensures treatment remains safe and suitable.
What is the difference between Mounjaro® and semaglutide (Wegovy® or Ozempic®)?
Semaglutide-based medications act on GLP-1 receptors to help regulate appetite and blood sugar levels.
Mounjaro® (tirzepatide) activates both GLP-1 and GIP receptors, offering a dual-pathway mechanism that may enhance appetite regulation and metabolic response in certain patients.
Your clinician will determine which therapy, if any, is appropriate based on your BMI, medical history and treatment goals.
Do I need to follow diet and exercise guidance while on treatment?
Yes. Prescription weight loss injections are designed to support, not replace, lifestyle modification.
For sustainable weight reduction and improved metabolic health, treatment should be combined with structured nutritional guidance, physical activity and behavioural support. Medication is most effective when integrated within a comprehensive medical weight management programme.
What happens if I stop GLP-1 weight loss treatment?
Some patients may experience partial weight regain after discontinuing medication, particularly if underlying lifestyle or metabolic drivers are not addressed.
For this reason, we focus on long-term weight management strategies and structured follow-up to support sustained results beyond medication alone.
What happens during the initial consultation
Your initial consultation includes:
Detailed medical history review
BMI and obesity risk assessment
Review of previous weight loss attempts
Screening for contraindications
Discussion of risks, benefits and expectations
This ensures that any prescribed treatment is safe, appropriate and tailored to your individual health profile.
How long will I need medical weight management treatment?
Treatment duration varies depending on your starting weight, metabolic health and long-term goals.
Some patients require short-to-medium-term support, while others may benefit from longer-term management under medical supervision. Decisions are made collaboratively and reviewed regularly to ensure the safest and most appropriate approach.
