Flare-ups refer to when the symptoms of Crohn’s disease or ulcerative colitis return after a period of time in remission, or low disease activity. They can happen at any time, and for no apparent reason. However, there may be some triggers for flares such as:

  • Stress
  • Missing medications or taking the wrong dose
  • Eating certain foods
  • Certain medications, other than your medicines for IBD
  • Smoking

Talk to your doctor if you have any questions about possible triggers for flares.

The Crohn’s & Colitis Foundation of America has a booklet explaining all about flares in Crohn’s disease and ulcerative colitis. Please note, some medications may not be available in Australia and there are differences in eligibility and PBS requirements for medications between Australia and the USA.
