Hi basil and welcome. I am glad you found this site too. Sorry you have to be here though. You will get lots of great information though.
As for the bleeding, for me that was the first and most persistent symptom I had. I just bled, bled, bled for about 15 years solid. Occasionally prednisone would stop if briefly, but not until I started Humira (over 2 years ago now) did the bleeding stop. It seemed that most people suffered from d the worst, but for me the most disturbing part was all that blood. Many times I would just go blood. Typically the whole toilet bowl was completely red and that is all you could see. After a while I just got used to seeing it. I would get weak and very tired. For me, changing my diet did not improve my symptoms. I hope it helps with you and that you can get the right medications to control your symptoms soon. Good luck.
I've been diagnosed with Crohns for 20 yrs and have bleeding when my crohns is active. One thing to keep in mind is that other things
can cause cramping and bloody stools. I bled for a yr and thought it was just my crohns. It turned out to be diverticultis which was causing all the blood. A simple blood test showed inactive crohns so they did a cat scan which showed my other problem. In short, 1 1/2 of bleeding ended with a sigmoid colectomy. Don't assume it is always your crohns!!!
