Do You Meet the Qualifications for Wegovy?

What BMI do you actually need to qualify for Wegovy?

The licence for Wegovy sets a BMI of 30 or above as the standard starting point for adults seeking it purely on weight grounds. If your BMI sits between 27 and 29.9, you can still qualify provided you have at least one weight-related condition alongside it — prediabetes, high cholesterol, obstructive sleep apnoea, osteoarthritis and hypertension are all recognised. The NHS BMI calculator at NHS.uk is worth using before your consultation, since it gives you a figure your prescriber will want to know.

For people from South Asian, Chinese, Middle Eastern, Black African or African-Caribbean backgrounds, UK guidance recognises that health risks associated with excess weight emerge at lower BMIs. The threshold for qualification drops by 2.5 kg/m² in each band, meaning a BMI of 27.5 can be sufficient, or 24.5 with a qualifying condition.

One thing worth saying plainly: the number on a calculator does not decide whether you receive treatment. A prescriber reads your answers, your health history and any relevant medication list. Two people with identical BMIs can reach different clinical decisions, and that is exactly as it should be. You can read more about who qualifies for semaglutide on its own page if you want the deeper detail.

Which health conditions count as qualifying criteria alongside BMI?

Wegovy's licence refers to weight-related health conditions without exhaustively listing them, so clinical judgement matters here. Conditions most commonly accepted include type 2 diabetes, prediabetes, high blood pressure, dyslipidaemia (raised cholesterol or triglycerides), obstructive sleep apnoea, and conditions where carrying excess weight puts significant strain on joints or the cardiovascular system. The NHS medicines page for semaglutide covers the licensed context in plain terms and is a reliable place to cross-check.

For people exploring the full scope of what semaglutide is approved for in the UK, including its cardiovascular indication, the indications for semaglutide page covers the complete picture. At nume, our prescribers assess weight-management indications specifically.

It is also worth knowing that these conditions need to be established, not self-diagnosed. Your prescriber will ask for relevant history and may want to know about current treatment or monitoring. That is not bureaucracy for its own sake; it is what makes a clinical review meaningful rather than a formality. Pregnancy, breastfeeding, and trying to conceive are all circumstances in which Wegovy is not recommended, and the medicine is not licensed for anyone under 18.

How do NHS qualifications for Wegovy differ from private ones?

On the NHS, Wegovy access is governed by NICE technology appraisal TA875, which recommends semaglutide only within specialist weight management services, for a maximum of two years, and sets higher qualifying thresholds than the licence alone. NHS patients generally need a BMI of 35 or above with at least one weight-related comorbidity, or meet specific referral criteria at 30 to 34.9. Waiting lists for NHS specialist services are often long, and the programme requires multidisciplinary support alongside the medicine.

Private prescribers follow the licensed eligibility rather than the NICE commissioning criteria, which means the BMI thresholds are lower and access does not depend on specialist referral or NHS service availability. If you are trying to understand where you can get Wegovy in the UK, it helps to know these two routes operate separately. A regulated online pharmacy like nume offers the private route: a GPhC-registered Independent Prescriber reviews your consultation the same day, and there is no waiting list to join.

Worth checking: any online pharmacy offering prescription medicines in the UK must be registered with the General Pharmaceutical Council. You can verify a pharmacy's registration at pharmacyregulation.org.

What happens if you are on the borderline of qualifying?

Being close to a BMI threshold is not the same as being ruled out. A prescriber looks at the whole person: your weight trajectory, your health history, what conditions are present and how they interact, whether other treatments have been tried. Someone with a BMI of 28 and well-managed type 2 diabetes sits in a clinically different place from someone with the same BMI and no weight-related conditions at all.

There are also practical considerations around other medicines. Wegovy can affect the absorption of oral contraceptives in some circumstances, and certain medication interactions with Wegovy are worth discussing before you start. Similarly, if you want to understand the potential side effects and complications of Wegovy before deciding, that information is available separately.

If you are trying to work out whether your situation fits, a consultation is the right next step. Our FAQs cover some of the more specific scenarios people raise, and our clinical team is there to assess the whole picture rather than just a number. Check your eligibility by starting a free consultation — it costs nothing, there is no obligation, and a prescriber reads every response personally.
