Anemia

Abstract

The evolution of anemia in the post-bariatric surgery patient is multifactorial and dependent on a number of variables, including the type of procedure performed and timing relative to the operative period. Most commonly, anemia develops in relation to micronutrient deficiencies because of altered metabolism and absorption after bypass-containing procedures. The routine addition of a multivitamin as well as supplemental iron, B12, and calcium with vitamin D to the diet of the patient undergoing bariatric surgery will help prevent most nutritional deficiencies that may contribute to anemia. A thorough understanding of the expected anatomic and physiologic changes after such surgery as well as common complications, including anemia, will empower the clinician to properly guide and manage the patient undergoing bariatric surgery.
