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 Access & Cost in the UK
Private prescription costs for Mounjaro typically range from £129 to £320 per month depending on the dose. Costs increase as you progress through dose titration — starting doses (2.5 mg) are at the lower end, while maintenance doses (10–15 mg) cost more. Each KwikPen contains 4 weekly injections. A private online consultation with a UK-licensed prescriber usually costs £45–£100, and the prescription is then dispensed by a GPhC-registered pharmacy. Private access means you don't need an NHS referral and can start treatment more quickly than waiting for specialist NHS services. However, you bear the full cost — there are currently no reductions or subsidies for private Mounjaro prescriptions in the UK. Use our free GLP-1 weight loss calculator to estimate potential weight loss at different doses, which may help inform your decision.

NHS vs Private: Which Route in Liverpool?
NHS access in Liverpool is through your GP referral to the integrated care board's specialist weight management service (tier 3). This is free at the point of use, but waiting lists are often lengthy — sometimes 6–12 months or longer depending on current demand. Private access is faster: complete an online assessment, receive a prescription from a UK-licensed prescriber if eligible, and begin within days. NICE has approved tirzepatide for NHS use, but availability and waiting times vary significantly across regions. Your GP can advise whether you meet local eligibility criteria (BMI ≥30, or BMI ≥27 with weight-related health conditions). For those who cannot wait or prefer immediate access, private prescription remains the quickest option. Compare your weight loss potential using our BMI calculator to understand your current health position and whether treatment eligibility applies to you.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What does Mounjaro cost on private prescription in Liverpool?
Private Mounjaro costs typically range from £129–£320 per month depending on your dose. Starting doses (2.5–5 mg) cost less; higher maintenance doses (10–15 mg) are more expensive. Prices vary slightly between private prescribers and pharmacies, so it's worth comparing. A private consultation usually costs £45–£100 upfront.
How long is the NHS waiting list for Mounjaro in Liverpool?
NHS waiting lists for tier 3 specialist weight management services in Liverpool vary. Current estimates suggest 6–12 months or longer depending on referral volume and ICB capacity. Ask your GP for a specific timeframe and whether your local service currently offers tirzepatide as part of their treatment pathway.
Am I eligible for Mounjaro on the NHS in Liverpool?
You may be eligible if you have a BMI of 30 or above, or 27–29.9 with weight-related health conditions (type 2 diabetes, high blood pressure, sleep apnoea, cardiovascular disease). Lower thresholds apply if you're of South Asian, Chinese, Black African, or Black Caribbean heritage. Your GP will assess your individual eligibility.
How quickly can I start private Mounjaro in Liverpool?
Private access is much faster than NHS. After completing an online consultation and receiving a prescription from a UK-licensed prescriber (usually within 24–48 hours if approved), your medication can be dispensed within days. Most people start treatment within 3–7 days of assessment.
What is tirzepatide and how is it different from Wegovy?
Tirzepatide (Mounjaro) is a dual GIP and GLP-1 receptor agonist — it activates two hormone pathways. Wegovy (semaglutide) is a GLP-1 agonist only. Clinical trials suggest tirzepatide may produce slightly higher average weight loss (~20.9% vs ~14.9%), but individual results vary significantly. Both are prescription-only and require clinical assessment.
