Assessment of Pancreatic Dysfunction in Patients With Type 2 Diabetes

The goal of this observational study is to better understand how the pancreas works in adults with type 2 diabetes. The study focuses on both hormone production (endocrine function) and digestive function (exocrine function) of the pancreas. The main questions it aims to answer are: * Can problems with the pancreas help identify a different type of diabetes called pancreatogenic diabetes? * How are blood markers and pancreas structure related to pancreatic function? Participants will: * Have blood tests to measure glucose, insulin, and other markers * Provide a stool sample to assess digestive function * Undergo an ultrasound examination of the pancreas * Answer questions about digestive symptoms The study will take place during a single visit in outpatient clinics.
