Abstract
Background/aim: Currently, the most widely performed surgical weight loss procedure in the treatment of morbid obesity is the Roux-en-Y gastric bypass (RYGBP) operation which combines restriction of food intake with malabsorption of calories and various nutrients, resulting in weight loss and nutritional deficiencies, respectively. Various types of anemia may complicate RYGBP of which iron deficiency anemia (IDA) is particularly common and may result from many mechanisms including poor intake, malabsorption, and mucosal bleeding from marginal ulceration. The objective of our study was to evaluate the effects RYGBP on iron status and iron absorption at different stages after surgery. We hypothesized that iron absorption would be markedly impaired immediately after surgery and would not improve after such a procedure.
