AI-Summary

What this Trial Is About

This research aims to understand how bariatric surgery affects the way the body processes the medication apixaban. Changes in stomach acidity, emptying time, and enzyme activity after surgeries like gastric bypass or sleeve gastrectomy may influence how much medicine is absorbed and available in the bloodstream. The study focuses on patients with severe obesity who are preparing for these types of surgeries. Participants will be observed taking their usual prescribed apixaban medication before and after their bariatric surgery. The study will measure apixaban levels in the blood from before surgery up to one year afterward to assess any changes in medication availability caused by the surgical procedures. During the study, participants will have blood tests to measure apixaban concentration over time. Researchers will monitor the medication's presence in the blood to understand how bariatric surgery impacts its absorption and effects. The study lasts up to one year after surgery, with regular follow-up assessments to track these changes.
