How to Qualify for Mounjaro in the UK

If you’re looking into Mounjaro (tirzepatide) as a weight loss option, the first thing to understand is that it’s a prescription-only medication in the UK. That means you’ll need to meet certain medical criteria before a prescriber can recommend it. These rules are in place to make sure the treatment is safe and suitable for you.

The General Eligibility Criteria

To qualify for Mounjaro in the UK, you’ll usually need to meet one of these requirements:

●        A Body Mass Index (BMI) of 30 or higher (classed as obese), or

●        A BMI of 27 or higher if you also have a weight-related health condition such as type 2 diabetes, high blood pressure or sleep apnoea.

It’s not just about the numbers, though. During your consultation, a prescriber will also look at your medical history, current medications, and whether Mounjaro is safe alongside any conditions you might have.

How Ethnicity Can Affect BMI Thresholds

You might be surprised to learn that BMI cut-offs aren’t the same for everyone. Research shows that people from certain ethnic backgrounds can develop weight-related health risks at a lower BMI compared to white European populations.

For example, people of:

●        South Asian heritage (Indian, Pakistani, Bangladeshi, Sri Lankan)

●        Chinese heritage

●        Black African heritage

…are at higher risk of conditions such as type 2 diabetes or high blood pressure at lower BMI values. Because of this, prescribers may consider you eligible for treatment at a BMI of 27 or even slightly lower, depending on your overall health profile.

This adjustment is recognised in UK healthcare guidance and helps ensure treatment decisions are based on actual health risks, not just standard BMI charts.

The Bottom Line
