Calculate
BMI

Body Mass Index (BMI) is a simple screening tool used to estimate whether a person is within a weight range that’s generally considered healthy for their height.

It’s calculated by dividing weight by height squared, and the resulting number places someone into categories like underweight, healthy weight, overweight, or obese.

While BMI can be a helpful starting point for understanding overall health, it doesn’t tell the whole story—things like muscle mass, age, ethnicity, and body composition can all affect the result.

So, BMI is best used as a guide rather than a judgment, and ideally alongside professional advice and how you feel in yourself, both physically and emotionally.

Eligibility Guidelines
for Starting
Weight-Loss Medication

Weight-loss medication may be considered for adults who are struggling to lose weight through lifestyle changes alone and meet certain health criteria. In most cases, eligibility includes:

  • A BMI of 30 or above, or

  • A BMI of 27–29.9 with a weight-related health condition, such as high blood pressure, high cholesterol, type 2 diabetes, sleep apnoea, PCOS, or joint issues.

  • Aged 18 or over.

  • No history of certain medical conditions that would make treatment unsafe (your clinician will screen for this).

  • Not pregnant or breastfeeding.

  • Not currently taking medication that may interact or conflict with treatment.

  • A willingness to engage in lifestyle changes alongside treatment for best results (nutrition, activity, mindset, routine).

Before starting, individuals usually complete:

  • A health and medication history questionnaire

  • A discussion or consultation with a trained clinician

  • A check that the medication is appropriate, safe, and likely to be beneficial
