Inflammatory bowel disease

Also called IBD

Inflammatory bowel disease (IBD) is a term mainly used to describe two long-term conditions that cause inflammation of the gut: Crohn's disease and ulcerative colitis. Symptoms tend to come and go, with periods of flare-ups and periods with few or no symptoms. It is different from irritable bowel syndrome (IBS).

What it is

The cause is not fully understood but involves the immune system, genes and the environment.

Medicines can reduce inflammation and keep the condition in remission. Some people need surgery.

Common signs

  • Diarrhoea that keeps coming back, sometimes with blood or mucus
  • Tummy pain and cramps
  • Extreme tiredness
  • Weight loss
  • Needing to rush to the toilet

How it is usually diagnosed

  • Blood tests
  • Stool test for calprotectin
  • Colonoscopy with biopsies
  • MRI or CT scans

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Calprotectin and blood test results over time
  • Colonoscopy and biopsy reports
  • Scan reports
  • Gastroenterology letters and a list of medicines

Questions to ask your doctor

  • Do I have Crohn's disease or ulcerative colitis?
  • What should I do during a flare-up?
  • How often do I need a colonoscopy?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Heavy bleeding from the bottom, severe tummy pain, a swollen tummy, or high fever: get urgent medical help
