Final answer:
Gastrointestinal bleeding occurs in approximately 15% of peptic ulcer disease cases, which are often associated with an H. pylori infection or the use of NSAIDs. Diagnosis generally involves symptom assessment and testing for H. pylori, but endoscopy may be needed, with treatment typically including antibiotics and acid-reducing medications.
Step-by-step explanation:
Gastrointestinal bleeding occurs in up to 15% of cases of peptic ulcer disease. A peptic ulcer is a sore that develops in the lining of the stomach or the duodenum, most often caused by an infection with the bacterium Helicobacter pylori. While indigestion and discomfort are common symptoms, significant bleeding is a serious complication that can occur. Diagnosing peptic ulcers typically involves assessing symptoms and testing for H. pylori, but endoscopy might be necessary for a definitive diagnosis. Treatment usually consists of a combination of antibiotics to eradicate H. pylori and medications to decrease stomach acid.
Peptic ulcers can also arise from the use of NSAIDs such as aspirin, and certain lifestyle factors may play a role in their development. When an ulcer causes gastrointestinal bleeding, immediate medical attention is required, and treatment strategies may include interventions to control bleeding and heal the ulcerated tissue.
