In this podcast episode, we interview Barry Marshall, AC, FRACP, FRS, FAA, the legendary Nobel Laureate who discovered that peptic ulcer disease was caused by the bacteria Helicobacter pylori, not excess acid. Marshall fought for years against the notion that ulcers were caused by acid and finally infected himself with the bacteria and underwent endoscopy to prove his point. His research has saved countless lives, as untreated ulcer disease can lead to gastric cancer. We discuss numerous facets of his life and his pioneering work. Before antimicrobial therapy against Helicobacter, patients suffered for years without the right therapy.
