- Infections: Helicobacter pylori have been primary culprits in gastrointestinal infections. Parasitic infection may also precipitate nausea and vomiting.
- Peptic ulcer disease: The ulceration impairs the protective lining of the stomach, which makes it highly irritable and sensitive to stimulants.
- Gastroesophageal reflux disease: Irritation of the esophagus brought about by the regurgitation of stomach contents can lead to nausea and vomiting.
