Relationship Between Changes in Gut Hormones After Gastric Bypass and Gastric Banding and Improvements in Diabetes

NCT01153438 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 8

Summary

The purpose of this study is to see how hormones that control blood sugar change in response to two different weight loss surgeries (gastric bypass and gastric banding). We believe that changes in a hormone called glucagon-like peptide-1 (GLP-1) may account for the greater improvement in blood sugar after certain types of surgeries. GLP-1 makes the pancreas release insulin, a hormone that lowers blood sugar. The study will consist of one screening visit and three study visits in which the glucose response will be measured after drinking a liquid meal: 1) Visit 1 (2-3 weeks before surgery); 2) Visit 2 (after 10% of body weight is lost); and 3) Visit 3 (5-10 days after Visit 2). Hormone levels will be measured during the three study visits. To see if the improvement in blood sugar after surgery is due to changes in GLP-1, we will block its effect on insulin release by giving either salt water or a medication that blocks the activity of GLP-1 during the two visits that take place after surgery (Visits 2 and 3).
