Special Issue Information

Dear Colleagues,

Clinically severe obesity can have serious health consequences for patients. Bariatric surgery has been established as the most effective treatment for morbidly obese patients, with a substantial reduction in mortality, risk of developing comorbidities, and costs.

  • Bariatric patients require scrupulous assessment and counseling in order to prolong weight loss and prevent nutritional deficiencies. The life-long metabolic and nutritional observance is suggested after bariatric surgery, mainly because pre-surgical deficiencies are common in morbidly obese patients and can be aggravated by restrictive or malabsorptive procedures.
  • Nutritional requirements in patients who have undergone bariatric surgery are frequently not met, and various nutritional deficiencies (vitamin B12, vitamin D, iron, calcium, etc.) are frequently observed as well. Accordingly, the adherence of patients to long-term supplementation regimens is poor in most cases.
  • Over the last ten years, clinical research on bariatric surgery has grown exponentially, mostly focusing on weight loss and reduction in comorbidities, but leaving gaps in the nutritional and health status of the subject after surgery in the long term.
  • This Special Issue of the International Journal of Environmental Research and Public Health (IJERPH) focuses on the current state of knowledge on The Nutritional Management of Pre- and Post-Surgery Obesity Patients. New research papers and reviews are welcome to this Issue.

Potential topics may include, but are not limited to:

  1. Preoperative nutritional management of patients with morbid obesity;
  2. Post-surgery diet progression;
  3. Perioperative nutritional, metabolic, and nonsurgical support of bariatric surgery patients;
  4. Micronutrient deficiencies after bariatric surgery;
  5. Nutritional outcomes after bariatric surgery and differences in racial and ethnic groups;
  6. Bone mineral density changes after bariatric surgery and relationship to vitamin D.

Best regards,

Long-Term Iron and Vitamin B12 Deficiency Are Present after Bariatric Surgery, despite the Widespread Use of Supplements

There are few long-term nutritional studies in subjects undergoing bariatric surgery that have assessed weight regain and nutritional deficiencies. In this study, we report data 8 years after surgery on weight loss, use of dietary supplements and deficit of micronutrients in a cohort of patients from five centres in central and northern Italy. The study group consisted of 52 subjects (age: 38.1 ± 10.6 y, 42 females): 16 patients had Roux-en-Y gastric bypass (RYGB), 25 patients had sleeve gastrectomy (SG) and 11 subjects had adjustable gastric banding (AGB). All three bariatric procedures led to sustained weight loss: the average percentage excess weight loss, defined as weight loss divided by excess weight based on ideal body weight, was 60.6% ± 32.3. Despite good adherence to prescribed supplements, 80.7% of subjects (72.7%, AGB; 76.7%, SG; 93.8 %, RYGB) reported at least one nutritional deficiency: iron (F 64.3% vs. M 30%), vitamin B12 (F 16.6% vs. M 10%), calcium (F 33.3% vs. M 0%) and vitamin D (F 38.1% vs. M 60%). Long-term nutritional deficiencies were greater than the general population among men for iron and among women for vitamin B12. Full article
