Which patients fulfil the referral criteria for weight loss surgery?

What sort of patients, what are the criteria to be referred for weight loss surgery, generally speaking? So that depends on the ratio of the patient's height to weight, known as BMI. Most patients that we operate on have a BMI of 35 or more, and a BMI of 20-25 is normal. Patients who have a BMI of 35 and above and any medical related comorbidity such as high blood pressure, polycystic ovaries, high cholesterol, obstructive sleep apnea, ischemic heart disease all qualify for bariatric surgery as per NICE guidelines. If you have diabetes, especially type 2 diabetes, then the criteria is a BMI of 30 or above with type 2 diabetes, especially if you've been recently diagnosed with this condition. If you're from the Asian subcontinent, then actually the BMI of 27.5 is enough to help you to be referred for bariatric surgery. This has been shown by diabetologists across the world to be the gold standard of treatment for type 2 diabetes.
