Bariatric surgery is now an essential option for the treatment of obesity and its associated comorbidity. Many patients presenting for surgery will have pre-existing vitamin deficiencies and all bariatric surgical procedures compromise nutrition to varying extents, and have the potential to cause clinically significant micronutrient deficiencies. Therefore, long term nutritional monitoring and follow-up are essential components of all bariatric surgical services. However, there are no current standard guidelines in the UK for the biochemical monitoring and replacement of essential micronutrients in patients undergoing different forms of bariatric surgery. Furthermore, a survey of members of BOMSS revealed a wide diversity of local guidelines and practices. This suggested a need for standard guidelines. We undertook a review of existing guidelines and the associated literature on micronutrient deficiencies following bariatric surgery. Our aim was to summarise existing evidence for the monitoring and replacement of vitamins and minerals prior to, and following bariatric surgery, and to make recommendations for safe practice in the UK setting. This publication is an abbreviated version of the fuller report.
