Referrals

Making a referral

We accept referrals from GPs.

Bariatric surgery (tier 4)

Your patient may be suitable for surgery if they have:

  • failed to maintain weight loss using non-surgical measures, such as tier 3 weight management
  • a body-mass index (BMI) between 30 to 35, with recent onset type 2 diabetes
  • a BMI between 35 and 40, with other significant disease that could improve if they lost weight (for example, type 2 diabetes or high blood pressure)
  • a BMI of more than 40
  • a BMI of more than 50kg (weight-loss surgery should be considered as first line treatment)

The first step on our obesity pathway is an online weight-loss surgery education group session. Your patient may not be suitable for this if they:

  • need an interpreter
  • have a significant learning difficulty
  • have already had bariatric surgery

If the patient is not suitable for this education session please note this in your referral.

Please make all referrals using the NHS e-Referral Service (e-RS).
