Ep 44: Endoscopy Explained – Everything You Need to Know

In this episode, I'm joined by Dr Natalie Kiel, gastroenterologist and endoscopist with expertise in inflammatory bowel disease, disorders of gut–brain interaction, and diagnostic endoscopy. We take a deep dive into gastroscopies and colonoscopies, covering everything patients need to know before, during, and after the procedure. Natalie explains what endoscopy actually involves, the differences between a gastroscopy and colonoscopy, why people are referred, and what symptoms should prompt further investigation. We also unpack one of the most talked-about parts of the process, bowel preparation. Natalie shares practical tips for making prep easier, explains what good bowel prep looks like, and discusses the most common mistakes that can affect procedure quality. We explore sedation, recovery, biopsies, polyps, procedure risks, and how scopes are cleaned and maintained to ensure patient safety. Natalie also discusses common findings during endoscopy, when biopsies are needed even when everything looks normal, and how endoscopy continues to evolve through new technologies and techniques. Whether you're preparing for your first gastroscopy or colonoscopy, supporting a loved one through the process, or simply curious about what happens behind the scenes, this episode provides practical, evidence-based answers to the questions patients ask most often. Please enjoy my conversation with Dr Natalie Kiel.
