Bristol Weight Management and Bariatric Service (BWMBS) - For Clinicians

Bristol Weight Management and Bariatric Service (BWMBS) encompasses a specialist Weight Assessment and Management Service (WAMS) and Bristol Bariatric Service (BBS) for individuals with obesity.

WAMS was previously known as the ‘Tier 3 Specialist Weight Management Service’. WAMS provides non-surgical, multi-disciplinary weight management support and interventions for a 6-12month period. This may be in the form of individual one-to-one appointments with a dietitian and / or psychologist, or through our 8 session Mood & Food group programme. WAMS also supports appropriate individuals to prepare for bariatric (weight loss) surgery with the ‘Bristol Bariatric Service’ (BBS).

It is national guidance that an individual receives intensive support from a specialist weight management service, such as WAMS, before they can be considered for a referral to a bariatric surgery team. There may be some exceptions to this rule for those who have other medical issues that require urgent treatment.
