Stomach Full of Courage: The Self-Experiment That Proved H. pylori Causes Ulcers

What drives a doctor to drink a flask of bacteria, knowing it could make him violently ill? In the early 1980s, Dr. Barry Marshall and Dr. Robin Warren stood against the entire medical establishment to prove that most ulcers were not caused by stress or acid, but by a spiral-shaped bacterium called Helicobacter pylori.

This discovery overturned decades of dogma, reshaped ulcer care, and ultimately won them the Nobel Prize. But it came at a cost: ridicule, resistance, and the risk of self-experimentation when no one else would listen.

In this episode of Tribulations, Dr. Ravi Kumar guides you through the story of persistence and courage that forever changed medicine. You’ll explore:

• The personal story of one patient’s suffering—and cure—thanks to antibiotics against H. pylori
• How Warren’s chance observations and Marshall’s tenacity cracked open a new understanding of ulcers
• The legendary self-experiment where Marshall infected himself to prove the point
• Why medicine resisted the idea for over a decade, leaving patients to suffer needlessly
• How eradicating H. pylori not only cures ulcers but reduces the risk of gastric cancer worldwide
• The timeless lesson: how courage and curiosity can topple even the most entrenched medical beliefs

It’s a gripping journey of science, sacrifice, and the power of persistence in the face of doubt.
