Another complication to keep in mind is short bowel syndrome (SBS). If too much of the small intestine is resected, IBD patients can develop SBS. The small intestine helps to absorb many of the nutrients we consume from eating. In SBS, the body is unable to absorb enough nutrients from the foods eaten because there is not enough small intestine to aid in the absorption process and this can lead to diarrhea, weight loss, dehydration and malnutrition among other symptoms.
