BMI 27 or 30: what a prescription depends on

Quick answer

The licence for these medicines is tied to BMI: from 30 in principle, and between 27 and 30 only together with at least one weight-related condition.

Which conditions count is listed in the licence by way of example and not exhaustively. Whether a prescription is possible is therefore always assessed by a doctor — not by a calculator and not by a questionnaire.

How BMI is calculated

BMI is weight divided by height squared. It is a crude measure and does not distinguish muscle from fat — for muscular men it therefore reads too high.

That is precisely why it never stands alone in a clinical assessment. Waist circumference, existing conditions, current medication and history all belong with it.

If you narrowly miss the threshold

Missing the threshold narrowly leaves you without this option, not without options. That is a question of licensing, not of how seriously your concern is taken.

Having a condition and not declaring it only defers the problem: the doctor then cannot assess safely, and assessing safely is what the questionnaire is for.
