What Is BMI and Why Does It Matter?
Body Mass Index (BMI) is the most widely used screening tool for assessing whether your weight falls within a healthy range. Used by the NHS, GPs, and weight management services across the UK, BMI provides a quick snapshot of your weight relative to your height. The formula is simple: your weight in kilograms divided by your height in metres squared (kg/m²).
While BMI isn't a perfect measure — it doesn't account for muscle mass, bone density, or fat distribution — it remains the standard first step in identifying potential weight-related health risks including type 2 diabetes, cardiovascular disease, high blood pressure, and certain cancers.
The NHS also recommends adjusted thresholds for people of South Asian, Chinese, or Black African heritage — a BMI of 23 or above is classified as overweight, and 27.5 as obese. Our calculator includes this adjustment as a one-click toggle.
Private Mounjaro Cost in the UK
Private prescription costs for Mounjaro in the UK typically range from £150 to £320 per month, depending on the dose and provider. The cost structure usually increases with each dose escalation, as you progress from the starting 2.5 mg dose through to the maximum 15 mg maintenance dose.
- Starting doses (2.5–5 mg): approximately £150–£180 per month
- Mid-range doses (7.5–10 mg): approximately £200–£240 per month
- Higher doses (12.5–15 mg): approximately £280–£320 per month
These prices are for the KwikPen injector device and include the private clinical assessment fee. No NHS prescription charge applies to private prescriptions. Costs vary between providers, so it's worth comparing prices across GPhC-registered online pharmacies. When budgeting, remember that Mounjaro requires ongoing treatment — it's not a one-off cost. Using our free GLP-1 weight loss calculator can help you estimate potential results, but cost considerations should be part of your decision-making process.

NHS vs Private Routes in Birmingham
In Birmingham, NHS access to Mounjaro is through tier 3 specialist weight management services, typically managed by your local Integrated Care Board (ICB). You'll need a GP referral and may face waiting lists of several months to a year in some areas. When Mounjaro is prescribed via the NHS, you pay the standard prescription charge (£9.90 in England) or nothing if exempt.
Private route: You can access Mounjaro immediately through an online consultation with a UK-licensed prescriber, without a GP referral. A simple online assessment determines eligibility based on your BMI and health history. If approved, your prescription is dispensed by a GPhC-registered pharmacy within days. Use our BMI calculator above to check your current BMI and see if you might meet initial eligibility criteria (typically BMI ≥30, or ≥27 with weight-related health conditions). The private route is faster but costs significantly more than NHS prescription charges.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is the difference between Mounjaro and Wegovy?
Both are prescription-only weight management injections licensed in the UK. Mounjaro (tirzepatide) is a dual GIP and GLP-1 receptor agonist, while Wegovy (semaglutide) is a GLP-1-only agonist. Clinical trials showed Mounjaro may produce slightly higher average weight loss (around 15–21% of body weight) compared to Wegovy (around 15%), though individual results vary. Both require ongoing injections and lifestyle changes.
Can I get Mounjaro through the NHS in Birmingham?
Yes, but through a specialist tier 3 weight management service, not your GP directly. You'll need a GP referral and may wait several months. NICE has approved tirzepatide for NHS use in specialist services for adults with BMI ≥30, or BMI 27–29.9 with weight-related health conditions like type 2 diabetes or high blood pressure. Availability and waiting times vary by Birmingham's local ICB.
How quickly will I lose weight on Mounjaro?
Clinical trials showed an average loss of around 15–21% of body weight over 72 weeks at maximum dose, alongside diet and exercise. However, results vary significantly between individuals — some lose more, some less. Weight loss typically begins within the first few weeks but accelerates as your dose increases. Our GLP-1 weight loss calculator can help estimate potential outcomes at different doses.
What happens if I stop taking Mounjaro?
Weight regain typically begins within weeks of stopping Mounjaro, as appetite hormones return to baseline. Clinical data suggests most people regain weight within months unless they maintain significant lifestyle changes. This is why Mounjaro is considered an ongoing treatment, not a temporary course. Your prescriber will discuss long-term management expectations before you start.
What are the main side effects I should know about?
Very common side effects include nausea, diarrhoea, vomiting, and constipation — usually mild and temporary as your body adjusts. Less common but serious side effects include severe stomach pain (possible pancreatitis) and gallbladder problems. Most people tolerate Mounjaro well, particularly as doses escalate gradually. Always report unexpected symptoms to your prescriber immediately.
