Can I take Wegovy? How to decide if it's right for you

Your BMI is the starting point, not the finish line

The licensed threshold for Wegovy in the UK sits at a BMI of 30 or above. If your BMI is between 27 and 29.9, you can still be considered, but only when a weight-related condition is part of the picture. Qualifying conditions include type 2 diabetes, high blood pressure, raised cholesterol, obstructive sleep apnoea and cardiovascular disease, among others. The BMI criteria for Wegovy are straightforward on paper, though they require an actual measurement rather than a self-estimate, which is one reason our process includes live weight verification on video.

There is also a common misconception worth clearing up gently: some people assume that being just over the BMI threshold guarantees a prescription. It doesn't. The number opens the door; a prescriber walks through it with you. Your overall health, current medications, any relevant family history and your goals all form part of that assessment. BMI is a blunt tool and clinicians know it.

If your background is South Asian, Chinese, Middle Eastern, Black African or African-Caribbean, NICE guidance recognises lower risk thresholds, typically 2.5 kg/m² below the standard figure, so a BMI of 27.5 might meet the 30 criterion in practice, and our page on the BMI needed to take Wegovy explains how these adjustments apply to your specific situation. The full eligibility picture for Wegovy covers these adjustments in detail.

Conditions that mean Wegovy may not be suitable

A prescriber will want to know about certain medical histories before issuing Wegovy. A personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia type 2 (MEN2) is a contraindication in the product's licensed terms. So is a history of pancreatitis. Severe kidney or liver disease, serious gastrointestinal conditions, and some medication combinations also require careful consideration.

The NHS patient information for semaglutide sets out a full list of medicines and conditions that warrant discussion, the NHS semaglutide medicine guide is a reliable place to check interactions before your consultation. If you are taking oral contraceptives, it is worth knowing that there is no equivalent evidence of reduced pill effectiveness with semaglutide that exists for tirzepatide, though your prescriber will cover this with you.

Wegovy is not recommended during pregnancy, breastfeeding or while trying to conceive. It is not licensed for anyone under 18. These are firm lines, not soft cautions. If your situation involves any of them, your consultation will address what, if anything, is appropriate instead.

The NHS route versus a private prescription

Wegovy is available on the NHS through specialist weight management services, under NICE guidance TA875, which recommends it for adults meeting the eligibility thresholds within a structured multidisciplinary programme and for a maximum of two years. In practice, NHS waiting lists for these services are long in most areas, and the criteria are strict.

A private prescription is the other route. Through a regulated online pharmacy, the process can move considerably faster: a consultation at no cost, a same-day clinical review by a named prescriber, and (if approved) dispatch that same day. If you want to understand what private treatment costs before committing, the Wegovy pricing page gives an honest breakdown of what a legitimate service includes. There are no hidden fees and no subscription at nume.

If you are weighing whether a short course makes sense rather than longer treatment, there is guidance on taking Wegovy short-term that is worth reading first. Duration is a clinical conversation, not a decision to make alone.

What happens if you are borderline or unsure

Being on the edge of the criteria is not unusual. A BMI of 29.8 with one weight-related condition is a genuinely borderline case, and many people arrive at a consultation unsure whether they qualify. That uncertainty is exactly what a prescriber is there to resolve. The consultation with our clinical team reviews your health information in full, the same day you submit it, by a GPhC-registered Independent Prescriber, not an automated scoring system.

If Wegovy is not the right fit, the prescriber will say so. They may discuss whether a different treatment is more appropriate, or whether the timing is right. A consultation that results in no prescription is still a proper clinical service. You can also browse our FAQs ahead of time if you have questions about the process, or reach out via our contact page if something specific is on your mind.

Deciding whether you can take Wegovy is ultimately a medical question with a clinical answer. It starts with a conversation. Speak to our prescribers through a free consultation and get a clear answer based on your own situation.
