What are the four types of stimuli for abdominal pain?
Acute Abdomen is characterized by abrupt onset of severe pain caused by infarction, perforation, inflammation, obstruction, or organ rupture. Surgical intervention is usually required.
- 1. Stretching or tension—visceral nociception
- 2. Inflammation—mediated by kinins, histamine, prostaglandins, and so on
- 3. Ischemia—similar to inflammation
- 4. Neoplasm—nerve invasion
