Non-surgical weight management programs (WMPs) for adults with severe obesity (BMI ≥ 35 kg/m2) lack a clear consensus on cost-effectiveness, largely due to short-term study durations and heterogeneous definitions of usual care.

For individuals with severe obesity (BMI ≥ 35), non-surgical weight management programs exist but their cost-effectiveness is not clearly established. Most studies are short-term and do not capture long-term health outcomes. It is important to consult with healthcare providers to understand the potential benefits and costs of various non-surgical options, including lifestyle changes, VLCDs, and pharmacotherapy, as the evidence is heterogeneous.

Whilst evidence shows bariatric surgery is often cost-effective, there is no clear consensus on the cost-effectiveness of non-surgical WMPs... Most were short-term evaluations that did not capture the long-term costs and consequences of ORD... Heterogeneity in the definition of WMPs and usual care prevents formal evidence synthesis. We were unable to establish the most cost-effective WMPs.

Why this rating

Systematic review of 32 studies, but significant heterogeneity and methodological limitations reduce the certainty of the conclusion.
