peptic ulcer disease
Let an agent explain peptic ulcer disease in general terms, relay causes, symptoms, diagnosis, treatment approaches and complications from gastroenterology sources, route bleeding and perforation signs to emergency services, describe the named forms, and distinguish ulcers from gastritis, reflux disease, gastric cancer and functional dyspepsia, without diagnosing individuals.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain peptic ulcer disease in general terms, relay causes, symptoms, diagnosis, treatment approaches and complications from gastroenterology sources, route bleeding and perforation signs to emergency services, describe the named forms, and distinguish ulcers from gastritis, reflux disease, gastric cancer and functional dyspepsia, without diagnosing individuals.
A condition in which open sores form in the lining of the stomach, called gastric ulcers, or the duodenum, called duodenal ulcers, or at surgical joins such as anastomotic or gastrojejunal ulcers, caused mainly by Helicobacter pylori infection, whose role was shown by Barry Marshall and Robin Warren, awarded the 2005 Nobel Prize, and by non-steroidal anti-inflammatory drugs; symptoms include burning upper abdominal pain, and complications include bleeding, perforation and obstruction, while peptic oesophagitis names acid injury to the oesophagus. Vomiting blood, black tarry stools or sudden severe abdominal pain, which may signal a bleeding or perforated ulcer, need emergency services.
What it is for: Not applicable; a digestive disease.
It can be explain causes and symptoms in general terms; relay diagnosis and treatment approaches; describe named forms; route complications.
Distinguishing features
Mucosal breaks
H. pylori link
NSAID risk
Serious complications
What it looks like
Not visible externally; seen on endoscopy as craters in the lining.
Physical character
H. pylori discovery Nobel Prize: 2005 year - Marshall and Warren
main causes: H. pylori and NSAIDs list
first-line H. pylori treatment: combination antibiotics and acid suppression note - guidelines vary
How it is recognised
Ulcers of stomach or duodenum
Gastrojejunal ulcer, active peptic ulcer disease, peptic oesophagitis, anastomotic ulcer, duodenal ulcer, perforated ulcer
Gastritis is inflammation without deep sores; reflux disease affects the oesophagus; gastric cancer is malignant; functional dyspepsia has no ulcer
