This study is looking at how gastric bypass and sleeve gastrectomy surgeries affect how your body handles sugar (glucose metabolism). Researchers want to understand the roles of hormones and nerves after you eat. They are testing two drugs: Exendin-(9-39) and Atropine, to see how they impact glucose and insulin levels. You might be able to join if you are between 18 and 65 years old and have had bariatric surgery with low blood sugar (hypoglycemia), or if you've had bariatric surgery without symptoms, or if you are a healthy person who hasn't had surgery and doesn't have diabetes. The main goal is to measure insulin levels after you eat. The study aims to enroll 200 participants, but its current status is unclear.
