A Study to Evaluate the Effect of Fasting Duration and Dulaglutide (LY2189265) Withholding on Gastric Retention in Participants With Type 2 Diabetes Mellitus

This study examines how long patients with type 2 diabetes should fast before surgery when they are taking a GLP-1 medication like dulaglutide (Trulicity), and whether stopping the drug beforehand helps the stomach empty properly before anaesthesia. This is important because GLP-1 drugs slow digestion, which can be a risk during surgery. **You may be eligible if...** - You have had type 2 diabetes for at least 6 months - Your diabetes is managed with diet and exercise, metformin, or one additional oral medication (DPP-4 or SGLT-2 inhibitor) - Your HbA1c (a measure of blood sugar control) is between 6.5% and 10% **You may NOT be eligible if...** - You have a known stomach condition or history of significant gastrointestinal surgery - You have poorly controlled diabetes outside the accepted range - You are on insulin or other diabetes medications not allowed by the study Talk to your doctor to see if this trial is right for you.
