Barry Marshall - Nobel Laureate in Medicine and Physiology
Barry James Marshall is an Australian physician and researcher who was awarded the Nobel Prize in Physiology or Medicine in He is best known for his groundbreaking discovery that the majority of stomach ulcers are caused by the bacterium Helicobacter pylori, which challenged the prevailing medical belief that ulcers were primarily caused by factors such as stress, spicy food, and excess stomach acid.
Early Life and Education
Barry Marshall was born on September 30, , in Kalgoorlie, Western Australia. When he was seven years old, his family relocated to Perth. He completed his medical degree at the University of Western Australia in , graduating with a Bachelor of Medicine and Surgery.
Research with Robin Warren
In , Marshall began working at the Royal Perth Hospital, where he crossed paths with Robin Warren, a senior pathologist with a lon
Scientist poisoned himself to prove groundbreaking medical discovery, won the Nobel Prize
Until the discovery of a bacteria called “Helicobacter pylori” in , doctors attributed peptic ulcers to lifestyle choices, emotional stress, and consumption of alcohol or spicy foods. Usually, businessmen who smoked a lot of cigarettes were diagnosed with ulcers during that time. In the following years, two revolutionary pathologists, Dr. Robin Warren and Dr. Barry Marshall, struggled to prove to clinicians and gastroenterologists that the bacteria was the culprit. Most of their initial efforts proved futile and their hypothesis was met with skepticism. So, Barry came up with an unconventional idea: poisoning themselves to create an ulcer and then treat it using antibiotics, hence proving their study. They won the Nobel Prize in , reported The New York Times.
According to News Medical, peptic ulcers are inflammatory sores within the inner lining of the stomach, duodenum section of the small intestine, and sometimes the esophagus, that often cause vomiting. Most of the early doctors considered that the main cause of ulcers was lifestyle choices and accumulated stress, and so they oft
Who is Barry Marshall?

Marshall and Robin Warren showed that the bacterium Helicobacter pylori is the cause of most peptic ulcers, reversing decades of medical doctrine holding that ulcers were caused by stress, spicy foods, and too much acid. This discovery has allowed for a breakthrough in understanding a causative link between Helicobacter pylori infection and stomach cancer.

The Doctor Who Drank Infectious Broth, Gave Himself an Ulcer, and Solved a Medical Mystery
For years an obscure doctor hailing from Australia’s hardscrabble west coast watched in horror as ulcer patients fell so ill that many had their stomach removed or bled until they died. That physician, an internist named Barry Marshall, was tormented because he knew there was a simple treatment for ulcers, which at that time afflicted 10 percent of all adults.
In Marshall began working with Robin Warren, the Royal Perth Hospital pathologist who, two years earlier, discovered the gut could be overrun by hardy, corkscrew-shaped bacteria called Helicobacter pylori. Biopsying ulcer patients and culturing the organisms in the lab, Marshall traced not just ulcers but also stomach cancer to this gut infection. The cure, he realized, was readily available: antibiotics. But mainstream gastroenterologists were dismissive, holding on to the old idea that ulcers were caused by stress.
Unable to make his case in studies with lab mice (because H. pylori affects only primates) and prohibited from experimenting on people, Marshall grew desperate. Finally he ran an experiment on the only human patient
