Medical weight management in London — personalised, doctor-supervised weight loss with long-term results.
Struggling with weight isn’t about willpower — it’s often about hormones, metabolism, and biology.
At Altera Medical, we provide evidence-based weight management in London, combining medical assessment, prescription treatments, and ongoing clinical supervision.
As a private weight loss clinic in London, we support patients with structured programmes that may include lifestyle guidance and, where appropriate, prescription weight loss injections such as GLP-1 therapies (appetite-regulating medications that work on hunger, satiety, and blood sugar control, including Mounjaro® and semaglutide).
Medical weight management focuses on understanding why weight loss is difficult — not just telling you to eat less.
Many people struggle despite dieting, exercise, and repeated attempts that don’t lead to lasting results. At Altera Medical, weight management is treated as a medical issue, not a cosmetic one. We assess metabolic health, hormones, and risk factors before recommending treatment, including clinically approved weight loss medication where appropriate.

Ongoing monitoring, support, and adjustment
For many people, repeated dieting fails not because of lack of effort, but because the body adapts.
Calorie restriction alone can slow metabolism, increase hunger hormones, and make weight regain more likely over time. Medical weight loss focuses on the biological drivers of weight gain. Hormones such as insulin, GLP-1, leptin, and cortisol play a central role in appetite regulation, fat storage, and energy balance.
When these systems are disrupted, weight loss becomes increasingly difficult despite strict dieting or exercise. By addressing appetite signalling, metabolic health, and hormonal regulation — rather than relying on willpower alone — medical weight management supports safer, more predictable, and more sustainable results.

GLP-1 medications such as Mounjaro® (tirzepatide) and semaglutide differ from traditional weight loss approaches.
Rather than relying solely on calorie restriction, GLP-1 therapies act on the brain and digestive system to reduce appetite, increase feelings of fullness, and improve blood sugar control. This helps patients naturally eat less without constant hunger or food preoccupation.
Other methods — including restrictive diets, supplements, or unsupervised injections — often fail to address these mechanisms and can lead to rebound weight gain. At Altera Medical, GLP-1 therapy is used as part of a medically supervised programme, not as a standalone solution.
We begin with a detailed discussion of your weight history, lifestyle, medical background, medications, and previous attempts at weight loss.
Your doctor assesses whether weight gain may be linked to hormonal imbalance, insulin resistance, or other metabolic factors.
Blood tests may be recommended to evaluate metabolic health or hormone levels. Tests are requested selectively — unnecessary investigations are avoided.
We explain all suitable options clearly, including lifestyle strategies and, where appropriate, prescription weight loss medication such as GLP-1 injections.
If medication is prescribed, it is done under strict medical supervision, with clear instructions on dosing, expectations, and side-effect management.
Weight management is not a one-off prescription. We provide follow-up, progress review, and treatment adjustments to support safe, sustainable results.
Our role is to guide treatment safely, adjust plans when needed, and support patients in maintaining results beyond the initial weight-loss phase.
Sustainable weight loss depends on more than medication alone. Long-term success is supported by:
Appropriate patient selection and eligibility assessment
Gradual dose increases when clinically appropriate
Regular medical monitoring and follow-up
Addressing lifestyle and metabolic factors alongside treatment
Our weight management programmes are medically supervised and transparently priced. Treatment is only prescribed following clinical assessment.
Medication dosage is increased gradually where clinically appropriate. Not all patients require higher doses.
*All prescriptions are issued by a GMC-registered doctor following medical assessment.
If weight loss feels frustrating or out of reach, a medical approach can provide clarity and structure.
*We serve patients across Greenwich, Blackhorse Road, Orpington, and surrounding areas of South East and East London.
Eligibility depends on BMI, medical history, and clinical assessment. A consultation is required before any prescription.
In some cases, yes. GLP-1 medications may be prescribed for weight loss even without diabetes, when clinically appropriate.
When prescribed and monitored by a doctor, GLP-1 weight loss treatments are considered safe for many patients. We assess risks individually.
Appetite reduction often begins within weeks, with gradual weight loss over time. Results vary between individuals.
Only if it is clinically appropriate. Many consultations focus first on assessment and discussion of options.
Mounjaro® (tirzepatide) works on two appetite-related pathways (GLP-1 and GIP), while Wegovy® and Ozempic® contain semaglutide, which targets GLP-1 alone. Some patients experience greater appetite control with tirzepatide, but suitability depends on individual assessment.
