Pathophysiology

• H.pylori is closely associated with both duodenal and gastric ulcers.
• The estimated lifetime risk for the development of peptic ulcer disease is 10-20%, in patients with H.pylori infection.
• H.pylori can be diagnosed in 60-100% of gastric ulcer patients and 90-100% in duodenal ulcer patients.
