Some signs and symptoms associated with SBO include the following:

  • Nausea/vomiting (60-80%): The vomitus can often be bilious in nature 

  • Constipation/absence of flatus (80-90%): Typically a later finding of SBO

  • Abdominal distention (60%)

  • Fever and tachycardia: Late findings and may be associated with strangulation
