Development of the illness / pathogenesis
The small intestine consists of different parts:
- Duodenum
- Jejunum
- Ileum
- Ileocecal valve
Each of these sections plays a different role in digestion and the uptake of nutrients. Because of this, problems depend on:
- The length and location of the removed part of the small intestine
- The presence or absesence of the ileocecal valve (reflux/backflow protection and bacteria barrier)
- Functionality of the remaining small intestine and the other digestive organs (stomach, pancreas, liver)
- Adaptation processes of the remaining intestine
