Questions about BMI requirements are common when GLP-1 treatment is discussed. At the same time, it is easy to get the impression that a certain BMI automatically leads to treatment, which is not how Swedish obesity care works. Here we explain how BMI is used, which comorbidities usually matter, and why an overall medical assessment is always required.
The basic threshold: BMI 30 or BMI 27 with comorbidity
In obesity treatment, GLP-1 is usually considered at BMI 30 or above, or at BMI 27 to 29.9 together with at least one weight-related comorbidity. Below BMI 27, GLP-1 treatment is normally not indicated in this context. Even when weight thresholds are met, a medical assessment of benefit, risks, contraindications and follow-up is still required.
Which comorbidities count?
Comorbidities that may matter in the assessment include type 2 diabetes, hypertension, dyslipidemia, obstructive sleep apnea, PCOS, fatty liver disease, joint problems linked to excess weight, and cardiovascular disease. The clinician weighs your overall health status and does not rely on a single diagnosis alone.
How are you assessed in a digital consultation?
The assessment is stepwise, and digital contact can work well in many cases. If blood tests, blood pressure checks, or a physical exam are needed, the assessment may have to be complemented locally or in person. The aim is to make a safe decision, not just a fast one.
Differences between Wegovy, Mounjaro and Ozempic criteria
Wegovy and Mounjaro are approved for obesity treatment and are usually assessed against obesity-related BMI thresholds. Ozempic is approved for type 2 diabetes, not obesity, and off-label prescribing for weight loss is generally not recommended by Swedish authorities. That is why the same medicine class can still be treated differently in practice.
What if your BMI is too low?
If your BMI is below 27, GLP-1 treatment is generally not indicated in obesity care. Other measures may be more appropriate, such as nutritional counseling, increased physical activity, behavioral support, or evaluation for other medical causes of weight change.
Common misunderstandings about BMI rules
A common myth is that everyone with overweight can get GLP-1. In reality, a medical review and specific BMI thresholds usually apply. Another misconception is that BMI is the only criterion. In practice, doctors also weigh comorbidity, prior treatment, contraindications, and whether long-term follow-up can be done safely.
Quick guide: Who may be eligible for GLP-1?
Steps in a digital assessment
- Provide your weight, height and medical history
- Have contact with a doctor or another responsible clinician
- The clinician reviews BMI, comorbidity, medicines and any needed tests
- If treatment is medically appropriate, a follow-up plan is created
