Can I Get Mounjaro With a BMI of 27? (November 2026)

01 · The short answer

Can you get Mounjaro with a BMI of 27?

You can get Mounjaro with a BMI of 27 if a prescriber confirms you have at least one weight-related condition. The licence covers adults with a BMI of 30 or above, or a BMI between 27 and 30 with at least one such condition. Treatment is used alongside a reduced-calorie diet and increased physical activity.¹¹¹

The conditions named in the licence are high blood pressure, high cholesterol, obstructive sleep apnoea, cardiovascular disease, prediabetes and type 2 diabetes. A prescriber assesses your BMI, medical history and current medicines before deciding whether Mounjaro is suitable.¹ If your BMI is closer to 28, our guide to getting Mounjaro at BMI 28 covers the same rules.

02 · NHS or private

NHS versus private access at BMI 27

NHS access is stricter than the licence. NICE recommends Mounjaro for adults with a BMI of at least 35 plus at least one weight-related condition, so a BMI of 27 sits below that recommendation.⁴ Mounjaro is available on the NHS, but access is being phased in over several years. The primary-care rollout began in June 2025 with the highest-need groups first, initially BMI 40 and above with four or more qualifying conditions.⁶

Full rollout is expected to take years. That is why many people who meet the licensed criteria choose regulated private treatment rather than waiting. Your GP can tell you what is available locally.

03 · Getting started

How to get Mounjaro at BMI 27 with us

The Mounjaro pen starts at 2.5mg, and your first pen costs £129.99 with code FIRST40 (standard price £169.99). Every later order is £25 off the standard price (code DOSE25). All six doses are in stock, supplied through official LillyDirect supply direct from Eli Lilly's UK distribution.

• Free online consultation. A short health questionnaire with no charge and no obligation. Start your free consultation and tell us about your BMI and any conditions.
• Prescriber review. A GPhC-registered prescriber reviews it, not a scoring script. Payment is taken when you place the order; if the prescriber decides the treatment is not suitable, the order is refunded automatically in full.
• Dispatch and delivery. Same-day dispatch when ordered by 3pm, then free next-day tracked delivery in temperature-controlled packaging. Saturday delivery is £14.99.

Klarna and pay-monthly options are available, with no subscription lock-in. Ongoing monthly reviews are included, and repeat orders re-check suitability rather than auto-shipping.

04 · Qualifying conditions

Which conditions count at BMI 27?

The licence names high blood pressure, high cholesterol, obstructive sleep apnoea, cardiovascular disease, prediabetes and type 2 diabetes as examples of weight-related conditions.¹

If you take medicine for blood pressure or cholesterol, or have been told you have prediabetes, mention it in the consultation along with all your current medicines. Having a diagnosis on record does not decide the outcome on its own, because the prescriber reviews the whole picture.¹¹

If you have no condition at BMI 27, the licence does not cover you, and that is a clinical boundary rather than a pricing one. Other routes are covered in our guides to weight loss injections at BMI 27 and taking Mounjaro if your BMI is 27.

05 · Ethnic background and BMI

Does ethnic background change the BMI threshold?

Yes, it can. People from South Asian, Chinese, other Asian, Middle Eastern, Black African or African-Caribbean backgrounds are at higher risk of weight-related health problems at a lower BMI. Clinical thresholds are usually reduced by 2.5 kg/m² for these groups.⁴

So if you are from one of these backgrounds, you may qualify at a lower BMI than the standard threshold. Tell the prescriber your background during the consultation. If your BMI is below 27, our guides on GLP-1 treatment below BMI 27 and weight loss drugs under BMI 27 explain how the same rules apply.

06 · Who should not take it

Who should not take Mounjaro, even at the right BMI

Meeting the BMI rule does not make Mounjaro suitable for everyone. You should not take it if you are allergic to tirzepatide or any of its ingredients, or during pregnancy or while trying to conceive.¹ Mounjaro must not be used during pregnancy, and it should be stopped at least one month before trying to conceive. If you become pregnant during treatment, stop the medicine and tell your prescriber promptly.

Your prescriber will take extra care, or may recommend against treatment, if you have a history of pancreatitis, severe gut or digestive disease, diabetic retinopathy or gallbladder problems. Share your full medical history and medicine list in the consultation.¹¹

In rodent studies tirzepatide caused thyroid C-cell tumours. It is not known whether this applies to humans, and no increase has been shown in human trials. Tell your prescriber if you or a close relative have had medullary thyroid cancer or the inherited condition MEN 2.¹

07 · What to expect

What to expect if you start at BMI 27

Weight loss on Mounjaro is gradual by design, so think in months rather than days. In the SURMOUNT-1 trial of 2,539 adults, people taking tirzepatide alongside diet and exercise lost on average 15% of body weight on 5mg, 19.5% on 10mg and 20.9% on 15mg over 72 weeks, compared with 3.1% with lifestyle changes alone. These are trial averages and individual results vary.²

As a worked example, for someone starting at 100 kg, 15% is about 15 kg. Trial averages do not predict your own result.

Everyone starts on 2.5mg once a week. That dose is about letting your body adjust, not about weight loss itself. After at least 4 weeks the dose rises to 5mg, then can step up by 2.5mg at minimum 4-week intervals to a maximum of 15mg. Many people settle at 5mg, 10mg or 15mg, and higher is not automatically better.¹

Your prescriber reviews your response. If you have lost less than 5% of your starting weight after 6 months on the highest dose you can tolerate, they will discuss whether continuing or stopping is right for you.¹

08 · Costs at lower BMI
