duodenal ulcer
C1/C2Specialized / Technical / Medical
Definition
Meaning
An open sore that develops on the lining of the first part of the small intestine (duodenum).
A peptic ulcer located specifically in the duodenum, caused by factors like infection with Helicobacter pylori bacteria or long-term use of nonsteroidal anti-inflammatory drugs, which erode the protective mucosal lining, leading to pain and potential complications such as bleeding or perforation.
Linguistics
Semantic Notes
While a type of peptic ulcer, specifying 'duodenal' distinguishes it from a gastric (stomach) ulcer. The term refers to the specific anatomical location of the ulceration.

Learning
Memory Aids
Mnemonic
DUOdenal Ulcer: think of a DUO (two) – it's the ulcer type found in the first part (like a duo starting point) of the small intestine, not the stomach.
Conceptual Metaphor
THE BODY IS A CONTAINER / CORROSION METAPHOR: A corrosive process (acid, bacteria) eats away at the inner lining/wall of the intestinal container, creating a hole or breach.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'duodenalnaya yazva' as the primary term; while technically correct, it's highly medical. In general conversation, a Russian speaker might default to the more common general term 'yazva zheludka' (stomach ulcer), which is inaccurate for a duodenal ulcer.
Common Mistakes
- Confusing it with a 'gastric ulcer' (stomach ulcer). Saying 'stomach ulcer' when referring specifically to a duodenal ulcer. Mispronouncing 'duodenal' (e.g., /daɪˈəʊdɪnəl/ instead of /ˌdjuːəʊˈdiːnəl/).

FAQ
Frequently Asked Questions
The primary cause in most cases is infection with Helicobacter pylori bacteria. Another major cause is prolonged use of NSAIDs (like ibuprofen or aspirin).
The key difference is location: a duodenal ulcer is in the duodenum (small intestine), while a gastric ulcer is in the stomach. The pain patterns and some risk factors can also differ.
While emotional stress was once thought to be a direct cause, it is now considered a contributing factor that may worsen symptoms or delay healing, but is not the primary cause for most ulcers.
Serious complications include bleeding (haemorrhage), perforation (a hole through the wall of the intestine), and obstruction (blockage of the intestinal passage).
