It took about 40 plus years to diagnose that I have Crohn's disease, and that only after a tumor removal/partial bowel removal etc etc operation! This was approximately 13 years ago. Since that time, I've had a few episodes, but nothing very major. I've been faithful to doctors' visits, tests, etc. But the biggest factors that I can point to for a comparatively good life, are: a very rigid eating pattern/diet, and taking the anti-inflammatory Pentasa medication, 2000 mils each day. For me, it seems that Pentasa has been a life saver! JLM
