You may find it interesting that there are two age ranges where Crohns is most commonly diagnosed -- adolescence to young adulthood, and a second, though smaller, window right around your age. And no, it is not necessarily progressive. Dr. Hanauer of the U of Chicago, says there is a subset fo Crohns patients -- which he estimates at about
20% -- who tend to have moderate stable disease over time. The progression seen in a lot of other patients is really related to the complications . . . longer disease leads to more fistulas, fissures, strictures, etc. But if there's one central and striking thing abvout Cronhns it is that no two patients are identical and everyone's disease course, severity, etc. can be very different.
