What BMI do I need for weight-loss injections in the UK?
In the UK, weight-loss injections such as Wegovy (semaglutide) and Mounjaro (tirzepatide) are licensed for adults with:
BMI 30 or above,
or BMI 27 or above with at least one weight-related medical condition (such as type 2 diabetes, high blood pressure, or sleep apnoea).
Eligibility is confirmed through a clinician-led assessment. At VSC, BMI is one factor — your full health profile is reviewed before prescribing.

Can I get GLP-1 injections with a BMI under 30?
Possibly — if your BMI is 27 or above and you have a qualifying weight-related condition, you may meet UK prescribing criteria.
GLP-1 medications are not approved for cosmetic weight loss. At VSC, prescriptions are not automatic. A UK-registered clinician assesses your medical history, current medications, and overall risk before confirming suitability.

Side effects support at VSC?
GLP-1 medications such as Mounjaro and Wegovy commonly cause gastrointestinal side effects including nausea, constipation, diarrhoea, or reduced appetite. These are usually mild and improve as the body adjusts.
At VSC, patients receive structured guidance during dose escalation. If side effects occur, clinicians can review and adjust treatment where medically appropriate.

Is BMI 27 enough for weight-loss injections?
A BMI of 27 may be sufficient if you also have a weight-related medical condition such as:
- Type 2 diabetes
- Hypertension
- Dyslipidaemia
- Sleep apnoea
Under UK guidance, BMI 27 alone does not automatically qualify. A clinician must confirm eligibility through a structured assessment.

Can I switch to VSC from another provider?
Yes. If you are already prescribed Mounjaro, Wegovy, or Saxenda, you may request to continue treatment with VSC.
Your current dosage and prescription history will be reviewed to ensure safe continuation. This helps prevent inappropriate dose escalation and supports structured, responsible prescribing.

Can I get weight-loss injections at BMI 25 or 26?
In most cases, no. In the UK, licensed weight-management indications for Wegovy and Mounjaro begin at:
BMI ≥30, or
BMI ≥27 with weight-related conditions
Prescribing below these thresholds would generally require strong clinical justification. At VSC, we prioritise responsible, safety-first prescribing aligned with UK medical guidance.

What BMI do I need for Ozempic?
Ozempic (semaglutide) is licensed in the UK for type 2 diabetes management, not specifically for weight loss.
For medical weight management, clinicians typically assess eligibility for Wegovy (higher-dose semaglutide) or Mounjaro (tirzepatide), which follow BMI thresholds of:
BMI ≥30, or
BMI ≥27 with weight-related conditions
A clinician determines which medication, if any, is appropriate.

Does BMI affect GLP-1 eligibility?
Yes. BMI is one of the primary criteria used to determine eligibility for GLP-1 weight-loss injections in the UK.
However, it is not the only factor. A clinician will also review:
- Medical history
- Cardiometabolic risk
- Current medications
- Previous weight
- Management attempts
At VSC, prescribing decisions are based on a complete clinical review — not BMI alone.
