There are three phases after surgery:
- The removal of a part of the small intestine is immediately followed by a period which approximately lasts two weeks and is characterized by a significant loss of fluids and electrolytes (hypersecretion). This fluid loss must be compensated and controlled by feeding fluid, electrolytes and nutrients directly into the bloodstream.
- The first phase is followed by a period of adjustment. The fluid loss is significantly reduced within a maximum of twelve months.
- The third is characterized by a Stabilisation and a significant reduction of diarrhea and fatty stools.
