How Is Constipation Diagnosed?

Most people do not need extensive testing to diagnose constipation. Only a small number of patients with constipation have a more serious medical problem.

If you have constipation for more than two weeks, you should see a doctor so heor she can determine the source of your problem and treat it. If constipation is caused by fungal colonies, early detection and treatment is very important.

Tests your doctor may perform to diagnose the cause of your constipationinclude:

  • Blood tests if a hormonal imbalance is suspected.
  • Barium studies to look for obstruction of the colon.
  • Colonoscopy to look forobstruction of the colon.

The vast majority of patients with constipation do not have any obvious illness to explain their symptoms and suffer from one of two problems:

  • Colonic inertia. A condition in which the colon contracts poorly andretains stool.
  • Obstructed defecation. A condition in which the person excessivelystrains to expel stool from the rectum.
