Summary

This study looks at whether taking a daily iron supplement after sleeve gastrectomy surgery can prevent iron deficiency anemia. Researchers will compare two groups of adults who had the surgery: one group takes extra iron plus a multivitamin, the other takes only a multivitamin. Blood tests and health surveys will track results for 6 months after surgery.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adults aged 18 to 65 years scheduled to undergo primary laparoscopic sleeve gastrectomy (LSG). * Capable of understanding and providing written informed consent for participation. * Able and willing to commit to the 6-month post-operative follow-up schedule at the bariatric clinic. Exclusion Criteria: * Prior history of major gastrointestinal surgery (e.g., bowel resection, gastrectomy) that could independently affect iron absorption. * Pre-existing malabsorptive conditions (e.g., inflammatory bowel disease, celiac disease). * Diagnosis of other known forms of anemia (e.g., thalassemia, vitamin B12/folate deficiency, anemia of chronic disease) that would confound the diagnosis of iron deficiency anemia (IDA). * Any condition that, in the investigator's judgment, would interfere with full participation in the study or pose a significant risk.
