How is Crohn's disease diagnosed?

Crohn's disease is diagnosed medical history, physical examination and various tests to confirm inflammation in the digestive tract. The diagnostic process typically includes:

1. Blood tests: To check for signs of inflammation, infection or anaemia, which are common in Crohn's disease.
2. Stool tests: Used to detect blood or infections in the stool, helping to rule out other conditions.
3. Endoscopy and colonoscopy: A camera is used to examine the inside of the digestive tract, allowing doctors to see inflammation, ulcers or other abnormalities. Tissue samples may be taken for analysis.
4. Imaging tests: Tests such as MRI, CT scans or intestinal ultrasounds may be used to view the digestive tract and identify areas of inflammation or blockages.
5. Capsule endoscopy: A small camera in a capsule is swallowed, allowing detailed images of the small intestine to be taken to help identify areas of Crohn's disease.
