What a doctor assesses

What a doctor assesses

A medicine is selected only after an individual medical assessment. BMI is one part of the decision, not the decision itself.

  • BMI, waist circumference and weight history
  • Related conditions and recent test results
  • Current medicines, allergies and contraindications
  • Previous treatment, goals and ability to attend follow-up
