Brief summary

The aim of the study is to compare the endocrine function of pancreas between pre and post metabolic surgery in patients with type 2 diabetes or prediabetes. The study will examine the endocrine function of pancreas using 18F-FDOPA PET/CT imaging and various biochemical laboratory tests
