Clinical Information for Peptic ulcer, site unspecified (K27)

Peptic Ulcer - Ulcer that occurs in the regions of the GASTROINTESTINAL TRACT which come into contact with GASTRIC JUICE containing PEPSIN and GASTRIC ACID. It occurs when there are defects in the MUCOSA barrier. The common forms of peptic ulcers are associated with HELICOBACTER PYLORI and the consumption of nonsteroidal anti-inflammatory drugs (NSAIDS).

Peptic Ulcer Hemorrhage - Bleeding from a PEPTIC ULCER that can be located in any segment of the GASTROINTESTINAL TRACT.

Peptic Ulcer Perforation - Penetration of a PEPTIC ULCER through the wall of DUODENUM or STOMACH allowing the leakage of luminal contents into the PERITONEAL CAVITY.
