Managing Micronutrient Deficiencies in the Bariatric Surgical Patient

  • Chapter
Treatment of the Obese Patient

Part of the book series: Contemporary Endocrinology ((COE))

Abstract

Bariatric surgery is associated with development of several micronutrient deficiencies that are predictable based on the surgically altered anatomy and the imposed dietary changes. The three restrictive malabsorptive procedures—Roux-en-Y gastric bypass (RYGB), biliopancreatic diversion (BPD), and biliopancreatic diversion with duodenal switch (BPD/DS) — pose a greater risk for micronutrient malabsorption and deficiency than the purely restrictive laparoscopic adjustable silicone gastric banding (LASGB). Metabolic and clinical deficiencies of two minerals (iron and calcium) and four vitamins (thiamine, folate, vitamin B12, vitamin D) have been well described in the literature. This chapter reviews the pathophysiology, clinical presentation, screening tests, and treatment for each micronutrient deficiency. With careful monitoring and adequate supplementation, these deficiencies are largely avoidable and treatable.
