Without treatment, symptoms of Crohn's disease can be constant or may come and go every few weeks or months.
Crohn's disease is a long-term condition where the gut becomes inflamed.
The main symptoms of Crohn's disease are diarrhoea, stomach aches and cramps, and blood in your poo.
The main treatments for Crohn's disease are medicines that reduce inflammation in your gut and stop it coming back. Some people need to have surgery.
The exact cause of Crohn's disease is unknown. It's been linked to things like your genes and a problem with the immune system.
