This is a timeline of the events relating to the discovery that peptic ulcer disease and some cancers are caused by H. pylori. In 2005, Barry Marshall and Robin Warren were awarded the Nobel Prize in Physiology or Medicine for their discovery that peptic ulcer disease (PUD) was primarily caused by Helicobacter pylori , a bacterium with affinity ...
Peptic ulcer disease is when the inner part of the stomach's gastric mucosa (lining of the stomach), the first part of the small intestine, or sometimes the lower esophagus, gets damaged. An ulcer in the stomach is called a gastric ulcer , while one in the first part of the intestines is a duodenal ulcer . [ 1 ]

In their nested case-control study, the researchers recorded a Parkinson’s diagnosis in 52 of the 2338 participants with MD (2.2%) and 48 of the 8955 people without MD (0.5%).
Several small studies conducted in the early 20th century demonstrated the presence of curved rods in the stomachs of many people with peptic ulcers and stomach cancers. [199] Interest in the bacteria waned, however, when an American study published in 1954 failed to observe the bacteria in 1180 stomach biopsies. [200]
The ulcer is known initially as a peptic ulcer before the ulcer burns through the full thickness of the stomach or duodenal wall. A diagnosis is made by taking an erect abdominal/chest X-ray (seeking air under the diaphragm). This is in fact one of the very few occasions in modern times where surgery is undertaken to treat an ulcer. [3]
Peptic ulcer disease including after endoscopic treatment for bleeding [11] As part of Helicobacter pylori eradication therapy [ 12 ] Gastroesophageal reflux disease (GERD or GORD) including symptomatic endoscopy-negative reflux disease [ 13 ] and associated laryngopharyngeal reflux causing laryngitis [ 14 ] and chronic cough [ 15 ]
