BOMSS Statement on announcement of the PM’s Obesity Strategy – 27 July 2020

We were pleased to hear the PM’s call for a more robust approach to tackling obesity during the COVID pandemic. The combination of a BMI >40 (our typical patient cohort) and coronavirus infection is a lethal cocktail, and so Mr Johnson’s reported desire to broaden the NHS’ focus to include more treatment was most welcome.

COVID-19 and Vitamin B12

As a result of pressures on services, and the requirement of vulnerable groups to self-isolate, we are aware that some people are unable to access timely vitamin B12 injections. BOMSS, RCGP and the BDA have worked together to issue practical guidance on the use of oral vitamin B12 in the short term. We strongly recommend that people return to vitamin B12 injections as soon as is practically possible.

BOMSS Restarting Bariatric Surgery Guidance

BOMSS have circulated best practice guidance about how to safely resume bariatric services now that elective surgery has restarted following the first COVID-19 wave.

Details of this guidance (which has been endorsed by both AUGIS and ALSGBI) can be found here.

We have also set up a Taskforce to support members during this difficult phase.

This will take the form of regular online meetings between BOMSS Executive and representatives of each UK unit to share advice and troubleshoot issues around resuming services, early experience and outcomes of bariatric surgery during the COVID era.

If you would like to take part in this Taskforce you should (i) select one representative from your unit who is a member of BOMSS and (ii) contact our secretary Vinod Menon at vinodmenon@btinternet.com

With my best wishes

From the President

Professor David Kerrigan

BOMSS President

The UK Bariatric Surgery Registry is one of the outstanding achievements of past BOMSS Council members. It contains data on over 60,000 patients and has clearly demonstrated that modern weight loss operations are highly effective and safe, with the potential to save the health service money by reducing the burden of diseases associated with obesity. So why is the annual volume of NHS-commissioned bariatric surgery – at under 6,000 operations a year – 5- 10 times less than most European countries?

Latest news

The BOMSS Guidelines on perioperative and postoperative biochemical monitoring and micronutrient replacement for patients undergoing bariatric surgery (2020 update) have been published in the Obesity Reviews. Access to nutritional assessments, life long follow-up including biochemical monitoring and vitamin and mineral supplementation is essential and requires input from a multiprofessional team. These guidelines give clear recommendations for assessment, biochemical monitoring and micronutrient replacement. They are the first bariatric surgery nutritional guidelines to cover both adults and adolescents and to include general practitioners and patient representatives in the working group. These guidelines have the potential to improve clinical practice and safety for people undergoing bariatric surgery and should be considered for adoption by healthcare organisations.
