Presentation Overview

For decades, stomach and duodenal ulcers were thought to be the consequence of excessive acid production by the stomach. Generations of patients were subjected to “sippy” diets, ineffective drugs with significant side effects, and life changing surgeries that left scars that affected more than their belly. That all changed in 1983 with the discovery of Helicobacter pylori (H. pylori) by Barry Marshall and Robin Warren from Australia.

H. pylori is one of the most common infections in humans and is the leading cause of inflammation in the stomach (gastritis) as well as stomach and duodenal ulcers (peptic ulcers). H. pylori has been implicated as a risk factor for stomach cancer in addition to a number of other medical conditions. H. pylori can be diagnosed using breath or stool tests or from biopsies obtained when a person undergoes upper endoscopy. Treatments consist of 2-4 drugs given for 14 days. All patients treated for H. pylori should undergo a test to prove the infection has been successfully cured.
