How eligibility is actually decided

BMI is a useful first filter, but it is only a starting point. The numbers below reflect the criteria most Canadian clinicians follow for prescription weight-management medication. A licensed clinician makes the final call after reviewing your full medical history, current medications and goals.

If your BMI is…General guidance
30 or aboveGenerally considered for GLP-1 therapy on BMI alone.
27 – 29.9Often appropriate with at least one weight-related condition (e.g. type 2 diabetes, high blood pressure, sleep apnea).
25 – 26.9Not typically treated with medication; a clinician may still discuss options if you have related conditions.
Below 25Within the healthy range — medication for weight loss isn't usually appropriate.

BMI doesn't tell the whole story

BMI doesn't distinguish muscle from fat, and it can read differently across ages, ethnicities and body compositions. People with more muscle may read "high" while being metabolically healthy. Treat your result as a conversation-starter, not a verdict.

What happens next

If you'd like to explore treatment, the next step is a free consultation. A Wexi clinician reviews your intake, confirms whether therapy is appropriate, and — only if it is — builds a plan with a slow, supported titration. Nothing is dispensed without that review.

  1. Complete a short intake. Your health history, medications and goals — about ten minutes.
  2. A clinician reviews your file. Typically within 72 hours, they confirm eligibility or suggest alternatives.
  3. Start with support. If appropriate, you begin at the lowest dose with weekly check-ins as you titrate.
This tool is not a diagnosis. Your BMI and the guidance shown here are for education only and don't constitute medical advice or a prescription. Only a licensed clinician can determine whether any treatment is right for you.
