Cramping within minutes of eating

Sounds like a partial obstruction to me. If this does not resolve soon, you need to call your doctor. If you had not had past major abdominal surgery, IBS would be a likely culprit. But with your history, you cannot assume that until you rule other causes out.

I'm so glad you said that because when I read about IBS it doesn't seem to be shortly after eating. I will do a real bowel rest like my surgeon recommends and give it a few days. Then if it's not better I'll call him. I don't feel hopeless now. Thank you, Jan.

In addition to what Jan suggested you might want to google IPS. That's what the official wording is for it after we get pouches.  There's one of Dr. Shen's, and others, studies that discusses using antibiotics for IPS treatment. It's been the same treatment as for pouchitis in my case.   

You might want to consider a c.diff infection too.  I had it before and after my colon was removed. Cramping and watery BM's are symptoms for it too. 

Lopermide, prescription Imodium, and/or Metamucil (I use generic gel caps) might slow things down.  If things don't respond to soft food and antibiotics I contract my GI and/or your surgeon. Whoever is taking care of your j-pouch problems. 

I hope you are feeling better soon.

Thanks. I'll do some reading on that. I had IBS a  few years before I got UC after a serious bout of C. Diff. It was bad for a while and then just sort of went away, I think. It was the early 90's and it's a little fuzzy for me now.
