Referral criteria

We accept referrals if patients meet the NICE (National Institute of Clinical Excellent) 2006 guidelines and NHS England criteria for funding bariatric surgery.

We require a referral letter from a medical practitioner, which should be addressed to a Consultant, before an appointment can be made. Please ensure that the patientís weight, height and BMI are stated clearly in the letter. Past medical and dieting history should also be included. Failure to include these details will result in a rejection of the referral.

All of the following criteria need to be fulfilled:
  • You must be willing to see various specialists that we recommend and follow our instructions.
  • You are generally fit for anaesthesia and surgery.
  • You commit yourself to the need for long-term follow-up.
  • You belong to one of the following categories:
  • Severely Obese (BMI 35-39.9) with co-morbidity e.g. type 2 diabetes, high blood pressure, osteoarthritis, metabolic syndrome etc.
  • Morbidly Obese (BMI 40-50), no co-morbidity required.
You would have tried non-surgical measures for at least six months and failed to achieve or maintain adequate clinically beneficial weight loss. However, if you are Super Obese (BMI > 50), then we waive this condition.
All patients must demonstrate evidence of engaging with dieticians / diet programs and undertaken exercise programs unless there are clinical reasons why these are not applicable. 

Body Mass Index (BMI)

The Body Mass Index is a tool that can be used to tell how healthy a person's weight is.
To work out your BMI, you need to take your weight in kilograms (kg) and divide it by your height in metres (m). Then divide the result by your height in metres (m) again.

For example, if you weigh 70kg, and you're 1.75m tall, your BMI would be 22.9 (70/1.75 = 40 and 40/1.75 = 22.9).
