Roux En Y Gastric Bypass

The ultimate goal of this research is to optimize care for patients undergoing laparoscopic bariatric surgery while alleviating pressure on hospital resources and staff. Furthermore, the study aims to generate policy-relevant data that can inform policymakers and healthcare providers in developing funding models and care pathways that balance safety, efficiency, and cost-effectiveness. This could support a broader implementation of ambulatory bariatric surgery without compromising quality of care.

The goal of this clinical trial is to characterize gastrointestinal digestion and physiology in patients after bariatric surgery, or people living with obesity. The main question it aims to answer is: what is the status of gastrointestinal digestion and physiology after bariatric surgery? Participants will have two study visits: 1) participants will undergo collection of gastrointestinal samples and 2) participants will ingest an ingestible capsule that measures multiple physiological parameters along the gastrointestinal tract.

The primary objective of the study is to compare the incidence of hypophosphatemia in RYGB patients treated with intravenous (IV) single dose of iron isomaltoside (Monofer®) or ferric carboxymaltose (Ferinject®).
