Diagnostic Considerations

It is important to be vigilant for colorectal cancer. Anal fissure should be considered in a constipated child. Colonic ileus secondary to sepsis or an intra-abdominal catastrophe may be misdiagnosed as constipation; large bowel obstruction may also be misdiagnosed as constipation.

In addition to the conditions listed in the differential diagnosis, the following problems should be considered:

  • Psychological causes

  • Diabetes mellitus

  • Hyperparathyroidism

  • Hypothyroidism

  • Uremia

  • Lead poisoning

  • Neuropathy

  • Parkinson disease

  • Multiple sclerosis

  • Spinal cord injuries

  • Scleroderma

  • Lupus

  • Amyloidosis
