Why No One Wants to Talk About Ulcers.
Fifty years ago, one of the biggest healthcare challenges was the stomach ulcer. Pharmaceuticals were making vast wealth off the introduction of new antacids to give patients some hope of better relief, but they were all told that they had a mental health problem. Namely, they weren't dealing with stress and their lives, and that stress created the ulcer.
So several millions of people were carrying a dangerous bacterial infection, and spreading it to many others. Not only were these patients lied to and left to suffer for the rest of their shortened lives; but they were shamed openly as poorly dealing with stress.
Then a curious county coroner in the Outback of Australia started collecting data on deceased individuals and saw the correlation of the bacterial presence and the health records indicating that ulcers were diagnosed. Dr. Barry Marshall eventually got the help of Dr. Robin Warren
But there was a complete stonewall of defiance from the established medical research gatekeepers. Every request for research help was immediately rebuffed without so much as curiosity about their unorthodox hypothesis.
