Crohn's disease - Diagnosis

How is Crohn's disease diagnosed?

For an accurate diagnosis, some examinations are necessary. At the beginning of the diagnosis, a complete patient survey and analysis of the medical history (anamnesis) are carried out.   Diseases within the family are also of interest.

The following examinations are included in the comprehensive diagnosis of Crohn's disease:

  • Palpation of the lower abdomen for pain upon pressure
  • Examination of the oral cavity and anus for signs of disease
  • Colonoscopy: The physician views the intestinal mucosa with an endoscope. He can also take samples, detect fistulae and treat narrowings directly.
  • Gastroscopy: A thin tube with camera is directed into the stomach through your mouth and through the esophagus. The duodenum can also be examined in this way.
  • Ultrasound: This examination is often repeated during therapy.
  • Imaging methods: Computer tomography (CT) or magnetic resonance tomography (MRI) can be used to visualize changes in the intestinal tract that were hidden during the endoscopic examination.
  • Blood tests: In the case of an inflammatory disease such as Crohn's disease, certain blood values are typically increased, especially the C-reactive protein (CRP)
