Diagnosing Crohn's Disease

Overview

Crohn's disease is a chronic condition in which the body's immune system mistakenly attacks the digestive tract and causes inflammation and irritation. To diagnose Crohn's disease, healthacare providers use a combination of tests, examinations, and procedures. These help confirm the presence of the disease and determine its type, severity, or stage. Here are examinations, tests, and procedures that may be used:

  • Physical Exam: During a physical exam, a healthcare provider will assess your overall health and look for signs that may suggest Crohn's disease, such as abdominal swelling or abnormal sounds within the digestive tract.
  • Medical History Review: The healthcare provider will review your medical history and family history to look for any indications that may explain your symptoms.
  • Blood Tests: Blood tests can reveal signs of anemia (lack of red blood cells), inflammation, or infection. They can also identify low red blood cell levels and possible anemia. Blood work also checks the sedimentation rate, which indicates the presence of inflammation in the body.
  • Stool Sample: A stool sample helps doctors detect infection and bleeding in the intestines.
  • Radiological Testing: Radiological tests, such as X-rays, CT scans (computerized tomography), and MRIs (magnetic resonance imaging), help healthcare providers visualize the function of the digestive tract and check for signs of irritation or inflammation in the bowel tissue.
  • Colonoscopy: This procedure uses a special camera to examine the colon for inflammation, which is a common sign of Crohn's disease. During a colonoscopy, healthcare providers can also take biopsies (samples) of bowel tissue for further examination.
  • Flexible Sigmoidoscopy: Similar to a colonoscopy, this procedure uses a special camera to examine the last section of the colon for inflammation.
  • Esophagogastroduodenoscopy (EGD): This procedure involves using a camera to look at the esophagus, stomach, and duodenum.
  • Small Intestine Imaging: In this test, you swallow a small camera that takes snapshots of your GI tract before being expelled in your stool. It helps doctors see any abnormalities in the small bowel.
  • Biopsy: During a colonoscopy or endoscopy, healthcare providers may take samples of your intestine for further examination under a microscope.

These examinations and tests are performed by various specialists involved in diagnosing Crohn's disease:

  • Gastroenterologists: These healthcare providers specialize in diagnosing and treating diseases of the digestive system.
  • Radiologists: They interpret radiological tests such as X-rays, CT scans, and MRIs.
  • Pathologists: They examine biopsy samples under a microscope to identify any abnormalities.
  • Primary Care Providers: They may refer you to specialists based on their initial assessment.

Remember that it is important to consult with a healthcare provider if you suspect you have Crohn's disease or have any concerning symptoms. They will be able to provide you with personalized advice and guidance based on your specific situation.
