Overview
Common causes of peptic ulcer disease include Helicobacter pylori infection and NSAID use. Less common causes of peptic ulcer disease include Crohn's disease, Zollinger-Ellison syndrome, Cushing and Curling ulcers, Carcinoid tumors, and carcinoid syndrome.
Causes
Less common causes
- Hormonal or mediator-induced including secondary acid hypersecretory states
- Antral G-cell hyperfunction
- Post-surgical antral exclusion and post gastric bypass surgery
- Cancers and lymphomas
- Cameron ulcer (gastric ulcer where a hiatus hernia passes through the diaphragmatic hiatus)
- True idiopathic ulcer
Rare causes of peptic ulcer disease
- Crohn’s disease of the stomach or duodenum
- Eosinophilic gastroduodenitis
- Systemic mastocytosis
- Radiation damage
- Viral infections (eg cytomegalovirus or herpes simplex infection, in particular in immunocompromised patients)
- Colonization of stomach with H heilmanii
- Severe systemic disease
Genetic causes[4]
- Peptic ulcer disease caused by gastrinomas (Zollinger-Ellison syndrome) caused by a mutation in MEN gene present on chromosome 11q13
