Gastric Band Wearers Have Nutrient Deficiencies Too


Between 2010-2013 around 26% of bariatric patients had gastric bands fitted (NBSR, 2015). With the updated NICE Guidelines (November 2014) recommending that in order to tackle the Type 2 diabetes epidemic the NHS should offer bariatric surgery to thousands more people each year, this will have a significant impact on the number of gastric band wearers in the UK. 


Many articles and reviews on bariatric surgery suggest that nutritional support is needed for those who have had a gastric bypass or gastric sleeve, yet gastric band wearers are generally fine.  Is this true? Or is more awareness needed regarding nutritional support for band wearer’s pre and post surgery?


Many obese individuals are deficient in nutrients prior to weight-loss surgery.  These are unlikely to improve after surgery without due care and attention. Data shows many gastric band wearers become deficient in:

  • Thiamin (B1).  Especially if patent has frequent vomiting (Dixon, 2001; Chavallier, 2010).

  • Folate (B9).  Folate levels decline by 44% within 2 years post surgery (Gasteyger et al., 2006)

  • Iron (Fe) Between 30-57% of patients are low prior to surgery, rising to 72% of patients within 18-months of surgery (Harris & Barger, 2010).

  • Protein (Coupaye et al., 2009).

  • Selenium (Freeth et al., 2012).

  • Vitamin C.  Up to 35% of patients are deficient 12-24 months post op (Clements et al., 2006).

  • Vitamin D.  Up to 80% of pre-bariatric patients are vitamin D deficient (Xanthakos, 2009).

  • Vitamin K.  Especially if the patient has prolonged vomiting (Van Mieghem et al., 2008).


Nicola and Claudia have extensively researched nutritional factors related to obesity, bariatric surgery and specifically nutrition to support gastric band wearers.  Their book has been written as a practical tool for the gastric band wearer but uses a scientific approach so that nutrition and bariatric professionals can use it with confidence, knowing that it’s evidence based.
