Researchers want to understand how gastric bypass and sleeve gastrectomy — two weight loss surgeries — affect how your body absorbs , a blood pressure medication. After these surgeries, your stomach and digestive system change in ways that might alter how medicines work in your body. This study will help doctors know if patients need different doses of this medication after surgery.
We know very little about how weight loss surgery changes the way common medications are absorbed and work in the body. This research will help doctors better manage medications for patients undergoing these surgeries.

You would be tested before your scheduled weight loss surgery and then again after it to measure how your body absorbs the blood pressure medication. The exact number and timing of visits will be determined by the research team, but the study involves small blood samples and measurements to track how the medication moves through your system.
