Crohn's disease - How common is Crohn's disease?
BMJ Group Medical Reference
Crohn's disease is fairly rare, affecting roughly 1 in 1,000 people. But it's becoming more common. Twice as many new cases are diagnosed now, compared with the 1950s.
Each year, there are around seven new cases of Crohn's disease for every 100,000 people. In total, about 140 in 100,000 people have Crohn's.
That means, in the UK, there are roughly 90,000 people with Crohn's disease.
Crohn's disease can affect people at any age. However, it's most often diagnosed in people between the ages of 16 and 30.
Crohn's seems to be slightly more common in women than men, but not by much. Most studies have found that between 5 and 6 out of 10 people who get Crohn's are women.
