Be Active, Stay Healthy

Be Active, Stay Health during COVID-19 Outbreak

Billions of people globally are staying at home to protect themselves and others from COVID-19. During this time, it’s key that children and adults stay active and healthy. Being active improves health, helps people deal with stress and most importantly helps our bodies fight off infections. Research shows that just 2 weeks of being less active has a negative impact upon health.

We’ve put together three short, easy-to-follow videos to help people stay active whilst at home. These exercises can be done at home in a small space and do no need any special equipment.

These videos are aimed at:

  1. Older adults, or people who are less active


  1. Active adults


  1. Children and young people

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.

COVID19 Statement

Dear Colleagues

Elective bariatric surgery in both the NHS and private sectors will effectively cease for the next 3- 6 months to help the NHS cope with the extraordinary pressures that the coronavirus outbreak has brought.

In the midst of this organised chaos and uncertainty it’s important that we support each other, our colleagues and our patients.

Bariatric surgeons are the most skilled and versatile laparoscopic surgeons in the UK.

We can use those skills in this crisis to improve the throughput and efficient management of emergency admissions through our hospitals, freeing the reduced number of emergency beds that will be available once Covid-19 patients flood the system.  Even those of us who work predominantly in independent hospital units can assist here, by redeploying ourselves and using the time freed by a lack of elective work to help cover emergency rotas and other duties in our local Trusts.  From personal experience I can reassure you that the Trust MDs and CEOs are very open to this.

We may no longer be performing bariatric cases, but we still have a responsibility to those we have already treated.

The generality of the NHS has rarely been good at handling the special needs of post-op bariatric patients who present as an emergency.

However, there are practical steps that we can take to safeguard their well-being during these difficult times, such as establishment of a bariatric helpline and a switch to remote telephone clinics with access to blood results etc. so that regular monitoring continues.

There is also still a need (albeit limited) for face to face contact with patients in genuine need of urgent help such as a band deflation.

We should take a lead in ensuring these safety nets are set up where we work.

After this storm has passed we will be changed as a nation and as a profession, but I believe this will be in a positive way given the camaraderie we share.

Bariatric surgery will return (and we need to have plans for how we deal with the inevitable backlog of work).

But in the meanwhile please keep safe, be patient and supportive under pressure and most of all, in the heat of battle do not lose your humanity.


With my best wishes

Alcohol and Your Health After Bariatric (Weight Loss) Surgery  

This patient education tool was developed by the Metabolic Surgery and Substance Addiction Group (MeSSAGe), a consortium of clinicians and researchers specializing in post-operative addiction issues after metabolic/bariatric surgery (MBS).  This resource is intended to help healthcare providers (particularly those within the MBS field) to educate patients about the risks of problems with alcohol and opioid medications after MBS.  This tool can be used with patients seeking MBS, to aid decision-making, treatment-planning and risk prevention; it can also be used with patients who have already undergone MBS, to increase awareness of risks and to aid in prevention and in timely identification and intervention for those who have encountered such issues.

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?
