The goal of this observational study is to learn about the carbon footprint produced from diagnostic upper GI endoscopy in patients with dyspepsia and therapeutic upper GI endoscopy in patients with non-variceal upper GI bleeding. The main question it aims to answer is:
• How much carbon footprint is generated from upper GI endoscopy Participants are already receiving diagnostic and therapeutic upper GI endoscopy as part of their regular medical care for dyspepsia and non-variceal upper GI bleeding, respectively. The carbon footprint generated from this treatment process is examined.
