Seeing your GP
To find out what the problem might be, your GP may ask about:
- your symptoms
- your diet
- if you've been abroad recently – you might have an infection
- any medicines you're taking
- if you have a family history of Crohn's disease
They may also:
- feel and examine your tummy
- take a sample of blood
- ask you to provide a poo (stool) sample
Blood and stool samples can be tested for things like inflammation – which could be due to Crohn's disease – and infections. It may take a few days or weeks to get the results.
Referral to a specialist
If they think you could have Crohn's disease, your GP may refer you to a doctor called a gastroenterologist for tests to confirm the diagnosis.
Tests you may have include:
- a colonoscopy – a thin, flexible tube with a camera at the end is inserted into your bottom to look for inflammation in your bowel
- a biopsy – tiny pieces of your bowel are removed during a colonoscopy and checked for signs of Crohn's disease
- an MRI scan or CT scan – you may have a special drink first to make your bowel show up clearly on the scan
What happens if you're diagnosed with Crohn's disease
If your doctor thinks you have Crohn's disease, they'll tell you about the condition and the treatment options.
It might be difficult to take in everything they tell you.
If you're unsure about something later, write down any questions you have and make another appointment to go over them.
