What is the referral criterion for bariatric surgery according to the obesity guidelines?

The referral criterion for bariatric surgery according to obesity guidelines typically specifies a Body Mass Index (BMI) greater than 35 when it is accompanied by weight-related comorbidities. This includes conditions such as type 2 diabetes, hypertension, sleep apnea, and other obesity-related health issues that significantly impact a person's quality of life and increase the risk of cardiovascular diseases and other complications.

Patients with a BMI over 35 often face serious health challenges directly linked to their weight, making them candidates for surgical interventions intended to promote significant weight loss and improve overall health outcomes. The surgery is not only aimed at weight reduction but primarily at enhancing health, reducing the risk of obesity-related comorbidities, and improving longevity.

In contrast, a BMI over 30 or propositions lacking associated comorbidities are generally not sufficient for surgery according to professional guidelines, as these patients might be effectively managed through lifestyle changes and medical therapies without the need for surgical intervention. The cutoff at BMI 40 or above suggests a more extreme level of obesity typically reserved for those at the highest risk of severe health consequences.
