Complex nutrition conditions that we treat:

  • Chronic intestinal pseudo-obstruction: a rare disorder of abnormalities in the normal involuntary coordinated muscular contractions (peristalsis) of the gastrointestinal tract
  • Intestinal failure: this can occur when a person’s intestines can’t digest food and absorb the fluids, electrolytes and nutrients required for normal growth
  • Short bowel syndrome: a condition of nutritional malabsorption or the surgical removal of a large portion of the small intestine.

The service provides:

  • outpatient clinics
  • multi-disciplinary meetings for intestinal failure patients
  • inpatient nutrition support and intestinal failure service supporting both acute and chronic intestinal failure in hospital.
