  • Abdominal pain
  • Abdominal distention
  • Abdominal tenderness
  • Fever
  • Rapid heart rate

Signs and tests

The rapid widening (dilation) of the colon makes this different from other conditions, such as chronic constipation, that can widen the colon slowly and do not cause sudden, life-threatening symptoms.

Tests:

  • Abdominal x-ray

  • Complete blood count
