You know, I've been wondering lately about that very subject: can I have IBS without a colon? I have an appt with my gastro doc next week and I sure will ask him. I bought a really good book by Heather Von Vorous called "IBS, the first year". I've tried to eliminate all dairy and animal fat and it seems to help a little. I just don't feel like I have the "typical" symptoms of IBS. I'm also going to ask my GYN next month about my problems. My 12 year old grandson seems to have inherited my colonic inertia but he's doing fairly well on Zelnorm. I tried EVERYTHING before my surgery and I'm just so thankful it helped so much. I pray you'll find some help and if you do have a colectomy that it will be a success and you'll heal completely. My surgeon said that I might have a temporary bag but thankfully I didn't. This is such a wonderful site...it reminds us that we're not alone. Take care and don't get discouraged.
Hope things are better for you. I've tried the Zelnorm but it gives me diarrhea so I really think watching what I eat is going to help more than anything. I did find out from my gastro doc that although most IBS is in the large intestine, it can be in the small intestine also. So I guess that's what I've got. I found out that stress really does make it worse...my mother passed away three days ago. But when your heart hurts, the stomach pain doesn't seem as important. But I think I don't have IBS as bad as some people; I'm thankful it's never been bad enough to go to the ER. Take care of yourself.
