Researchers want to understand how weight loss surgery affects the way your body handles medications. When you have gastric bypass or sleeve gastrectomy, your stomach and digestive system change shape and function. This study is looking at whether —a medication used to treat high blood pressure—works differently after this kind of surgery.
Doctors don't yet know how much weight loss surgery changes the way the body absorbs and processes common medications like blood pressure drugs. Understanding this could help doctors adjust medication doses safely for patients who have had this surgery.

You would donate blood samples before your weight loss surgery and again after it to measure how your body processes the medication at each stage. The study involves a small group of 12 participants total. Researchers will analyze these samples to see whether the surgery changes how much of the medication reaches your bloodstream.
