This usually happens to me when I've eaten something that irritates the intestinal linings. It looks like little bits of clotting, but is actually bloody mucous that another poster mentioned. For me, corn meal and corn flour react in me like food poisoning, and usually cause bloody stools like this. A bland diet with nothing even slightly risky usually clears this up within 24 hours. But, from what I've seen, this diet issue is individual to each person, with different things irritating each of us. There is a LONG list of potentially irritating foods for Crohn's, and you'll need to figure out your own list. Corn seems to be on most of the lists tho as taboo.
The gurgling and severe gut pain you talk about I have also, and is always related to the ileum swelling up and closing off the digestion, right where the small intestine attaches to the large intestine. Keeping the swelling down with the steroids and bland but NUTRITIONAL eating levels this off for me (so far). I was diagnosed in '91, and probably had it for years before that.
Any longer than 24 hours really MUST get back to your gastroenterologist RIGHT AWAY. These forums help very much, but we're not doctors. I also agree with previous posters to be absolutely as complete as possible in reporting what's happening with you. Severity, how much, how often, for how long, etc.
After you've cleared through this episode, there are several threads here that talk about diet and about supplements, which have been very useful for me. Doctors are needed and wonderful, but mostly help with the emergency moments. I've found that we just don't know all that much about Crohn's yet. This is a combination of drugs and supplements that have kept the swelling down and the BMs less frequent and more solid.
I take all of these twice a day:
1000mg of Pentasa;
1000-2000 mg omega 3 (not 6 or 9) fish oil;
I have colonoscopies every 2 years, and they have revealed Crohn's only at the end of my small intestine, so all of my treatments target the small intestine. Other treatments also address large intestine, esophagus, wherever your problems occur.
Hope it helps. Stay close with the GE FIRST, and be sure to handle the flareup, which can get very bad if not carefully treated. Then for day-to-day, these forums are really life-savers.
