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.[9]

Each year, there are around seven new cases of Crohn's disease for every 100,000 people.[10] 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.[10]

Crohn's disease can affect people at any age. However, it's most often diagnosed in people between the ages of 16 and 30.[10][11]

Crohn's seems to be slightly more common in women than men, but not by much.[11] Most studies have found that between 5 and 6 out of 10 people who get Crohn's are women.
