What criteria should I use to refer a patient for bariatric surgery?

Offer adults a referral for a comprehensive assessment by specialist weight management services to consider bariatric surgery if:

• The person has a body mass index (BMI) of 40 kg/m² or more.
• Or the person has a BMI between 35 and 40 kg/m² with a significant health condition that could be improved by weight loss, such as type 2 diabetes, hypertension, or severe mobility problems.
• The person agrees to the necessary long-term follow-up after surgery, including life-long reviews.
• For people of South Asian, Chinese, other Asian, Middle Eastern, Black African, or African-Caribbean family backgrounds, consider a lower BMI threshold reduced by 2.5 kg/m² due to increased cardiometabolic risk at lower BMI.
