The unit is a service for local patients but we can accept tertiary referrals from anywhere in the UK.

Referrals can be sent via the electronic referral service (e-RS) and this is our preferred method of receiving referrals.

Referral criteria

  • Bariatric surgery ( tier 4)

    The unit can accept patients with obesity meeting NICE clinical guideline criteria for bariatric surgical intervention. Patients may be suitable for surgery if they have:

    • tried appropriate non-surgical measures such as tier 3 weight management but has not achieved or maintained adequate, clinically beneficial weight loss
    • BMI 30-35kg/m2 with recent onset type 2 diabetes
    • BMI of 40kg/m2 or between 35-40kg/m2 with other significant disease that could be improved if they lost weight (eg type 2 diabetes or high blood pressure)
    • BMI of more than 50kg/m2. In this case bariatric surgery is the treatment option of choice.
