Short bowel syndrome is a complex disease that occurs due to the physical loss or the loss of function of a portion of the small and/or large intestine. Consequently, individuals with short bowel syndrome often have a reduced ability to absorb nutrients such as fats, carbohydrates (sugars) vitamins, minerals, trace elements and fluids (malabsorption). The disease is primary short bowel syndrome (EFO_0700081, an Experimental Factor Ontology id).
