Is Wegovy licensed if you're only slightly overweight?

The misconception most people arrive with

A lot of people assume that Wegovy is reserved for those who are significantly obese, that if you're "only a bit overweight" you won't qualify. That's one half of a misunderstanding. The other half runs the other way: the idea that any BMI over 27 is enough to get a prescription. Neither is quite right, and it's worth letting both of those go gently.

The UK licence for semaglutide (Wegovy) as a weight management medicine covers two distinct groups. The first is adults with a BMI of 30 or above. The second is adults with a BMI between 27 and 29.9 (what most people would call slightly overweight) provided they have at least one weight-related health condition. The NHS medicines page for semaglutide sets out this framework clearly, and it reflects the approved Summary of Product Characteristics.

Weight-related conditions that count in this context include type 2 diabetes, high blood pressure, dyslipidaemia (raised cholesterol or triglycerides), obstructive sleep apnoea, and cardiovascular disease. Prediabetes and osteoarthritis are also considered by prescribers. If your BMI is 28 and you've been managing hypertension for two years, you could sit within the licensed eligibility range. If your BMI is 28 and your health checks are otherwise unremarkable, the licence simply doesn't cover it.

This isn't a bureaucratic quirk. The weight-related condition requirement reflects the clinical rationale: the benefit-risk calculation for a prescription medicine shifts meaningfully when excess weight is already affecting your health.

How BMI is only part of what a prescriber weighs up

BMI is a starting point, not a verdict. A prescriber looking at someone in the 27–29.9 range is really asking: is this person's weight affecting their health right now, in a documented way? The number on the scale matters less than what it's doing to the body carrying it.

For context on exactly how these BMI thresholds work in practice, the detail on what BMI is needed for Wegovy covers the ranges and the conditions that apply at each level. It's also worth knowing that lower BMI thresholds apply for certain ethnic backgrounds under UK guidance, the adjustment is 2.5 kg/m² lower across the board, so a BMI of 25 with a qualifying condition could bring someone into scope.

Beyond BMI and qualifying conditions, a prescriber will also consider your medical history, any medications you take, and whether Wegovy is appropriate for you specifically. There are conditions where it's not recommended regardless of BMI. A history of pancreatitis, certain thyroid conditions, and pregnancy are among the contraindications a clinician will screen for. The assessment exists to protect you, not to put up obstacles.

One thing prescribers at a service like nume will always review is whether the weight-related condition you mention is documented, not self-reported, but verifiable. That's standard clinical practice for any prescription medicine.

NHS criteria versus the private licensed route

NHS access to Wegovy operates under NICE guidance (TA875), which layers additional requirements on top of the licence: the treatment must be provided within a specialist weight management service, and it's recommended for a maximum of two years. NHS waiting lists are often long, and the eligibility criteria are narrower in practice than the licensed indication alone. You can read the NICE appraisal of semaglutide (TA875) for the full technical picture.

Private prescribing through a regulated online pharmacy follows the product licence rather than the NICE commissioning criteria. That means the 27–29.9 with a qualifying condition pathway is genuinely open if you meet it, but it still requires a real clinical assessment, ID verification, and a prescriber who reviews your full answers before any decision is made. No assessment means no prescription; that's not optional, it's the law.

If cost is part of your thinking, the cost context for Wegovy in the UK explains what private treatment typically involves and what legitimate pricing covers. And if you're unsure whether Wegovy or an alternative is the better fit, the weight loss treatment overview sets out the full picture of what's available.

What to do if you're not sure whether you qualify

The honest answer is: ask. A consultation with a qualified prescriber is the only way to get a reliable answer for your specific situation. Generic eligibility guides (including this one) can tell you what the licence says. They can't tell you what a prescriber will conclude about you.

At nume, every consultation is reviewed the same day by a GPhC-registered Independent Prescriber. There's no algorithm deciding your suitability; a clinician reads your answers and health information directly. If you'd like to understand more about the criteria in plain terms before you start, the criteria for Wegovy for weight loss is a useful read, as is the guide on how overweight you need to be. If you want to dig further into the specific thresholds, this page looking at how overweight you need to be for Wegovy goes into useful detail, and the guidance on how overweight you need to be to use Wegovy is worth reading alongside it.

If the assessment confirms you're clinically suitable, and you order before noon on a working day, treatment is dispatched the same day and delivered free the next working day by DPD in plain packaging. If it doesn't, our prescribers will tell you why and what your options are. That conversation is free either way.
