Letter to the Editor

Bariatric surgery (BS) is the most effective long-term solution for the treatment and control of morbid obesity. However, the nutritional deficiencies and malnutrition associated with BS present major challenges for patients and clinicians. Herein, we use clinical experience and evidence-based recommendations to review the role of a nutritionist in a multidisciplinary bariatric team before surgery and in postoperative follow-up.

Although data is lacking from randomized controlled trials, large prospective studies or meta-analysis supporting mandated pre-BS weight loss, we recommend a preoperative diet to reduce body weight, liver volume, and intraabdominal fat; identify and correct micronutrients deficiencies (MD); transform the quality of diets and eating habits post-surgery [1].

Obese patients scheduled for BS often have an enlarged steatotic liver that may render the surgical procedure technically challenging, resulting in longer operative times, increased risk of intraoperative...
