Researchers want to understand how bariatric surgery—a type of weight loss surgery that changes the size and shape of your stomach—affects how your body absorbs and processes medications. This study is specifically looking at , a medication often used to treat nerve pain. By studying people before and after their surgery, doctors hope to learn whether they need to adjust medication doses for patients who have had this procedure.
When you have weight loss surgery, your stomach and digestive system change in ways that can affect how medications move through your body and get absorbed into your bloodstream. Doctors don't yet know for certain how these changes impact the medication, so this study aims to fill that gap so they can give patients the safest and most effective doses.

You would have blood samples taken before your weight loss surgery and then again after the procedure to measure how your body is processing the medication. The study team will compare these results to see what changed after your surgery. Your participation helps doctors understand whether patients need different medication doses following this type of surgery.
