Can I Get Wegovy If My BMI Is 25? What the UK Licence Actually Says

Why the Wegovy licence starts at 27 (or 30), not 25

Wegovy's approval in the UK is tied to specific benefit-risk evidence gathered in trials enrolling people with obesity or overweight plus health complications. The MHRA granted the licence based on that evidence base, and the lower boundary (BMI 27 with a qualifying condition) reflects where the clinical benefit was demonstrated to outweigh the risks. If you are wondering about whether a BMI of 25 makes you eligible for Wegovy, the short answer is that the population studied at that level simply wasn't the one for whom the medicine was assessed.

This isn't a guideline that clinicians can quietly set aside. A prescriber who issues Wegovy to someone at BMI 25 without a qualifying condition would be acting outside the product's licensed indications. That carries regulatory and professional consequences, which is why any legitimate pharmacy will hold that line even if you push back. The NHS semaglutide medicines page confirms the eligibility requirements plainly: BMI 30 or above, or 27 with a weight-related comorbidity.

The qualifying conditions that bring the lower threshold into play include type 2 diabetes, prediabetes, high blood pressure, high cholesterol and obstructive sleep apnoea. If you have one of those and your BMI is 27 or above, the picture changes. At 25 (even with a comorbidity) you remain below both doors.

What 'overweight at BMI 25' actually means for treatment eligibility

A question our prescribers hear most weeks goes roughly like this: "I'm only a few kilos over my ideal weight, can I just do a course to shift it?" It's an honest question, and the honest answer is no, not through Wegovy or tirzepatide, for the reasons above.

At BMI 25, your weight sits within what the NHS classifies as the overweight range, but the medicines licensed for weight management are aimed at people whose weight poses a more significant health risk. That framing isn't a value judgement; it reflects the populations in whom the medicines have been tested and found to offer a positive benefit-risk balance.

If you want to understand what BMI you need to get Wegovy and what conditions might shift things, that page is worth reading carefully. You can also use the NHS BMI calculator to check your figure precisely, a single decimal point can matter here. If you're tracking your weight and your BMI is edging towards 27, and you carry a condition like hypertension or high cholesterol, the picture at that point is meaningfully different from where you are at 25 today.

What the NICE recommendations add to this picture

NICE issued its recommendation for semaglutide (Wegovy) under technology appraisal TA875, setting out the conditions under which the NHS will fund it. The NHS threshold is, if anything, stricter than the licence alone: a BMI of 35 or above (or 30 to 34.9 under certain referral criteria), at least one weight-related comorbidity, and access through a specialist weight management service. Maximum two years of treatment.

Private prescribing works from the licensed indications, not the NICE NHS criteria, so the floor is lower in a private setting. But 25 is still below it. There is no private workaround to a licensing boundary. If you're weighing up the private route more broadly, our page on how to get Wegovy in the UK explains what the process looks like for people who do qualify. And if your question is about whether a GP could refer you, what a GP can do depends heavily on which criteria your surgery is working to.

The cost question comes up too. If you're weighing private treatment, our weight-loss treatments overview sets out what's involved. A short sentence on value: for a prescription medicine, clinical suitability matters more than price, and a BMI of 25 is, for now, a clinical no regardless of what you're prepared to pay.

If your BMI is 25 right now: honest next steps

The most useful thing you can do is keep the number in view. BMI is only one measure, waist circumference, existing health conditions, family history and metabolic markers all feed into a fuller clinical picture. If your GP has flagged any weight-related conditions, that conversation is worth revisiting as your BMI changes.

For people whose BMI is in the 27 to 29.9 range with a qualifying condition, or 30 and above, a private consultation with a registered prescriber is a real, same-day option through a GPhC-registered pharmacy. Our page covering the BMI requirements for Wegovy sets out the thresholds clearly if you want to confirm exactly where you stand before booking, and if you're unsure how the specific number translates into eligibility, our guide on what BMI is needed to get Wegovy walks through the detail. At 25, that route isn't open yet. The clinical team at nume follows the licensed indications precisely, because that's what regulated prescribing requires.

If you're not sure where you sit on the eligibility picture (or your BMI has changed recently) our prescribers can talk you through the detail. That starts with a free consultation, where nothing is prescribed unless the clinical assessment supports it.
