I don’t know if obstructions are common, I’ve only had the one hospitalization and that was a perfect storm of traveling, being kind of dehydrated, and some really fiberous romaine lettuce in a side salad, that I only ate part of at lunch time, by bedtime I could tell nothing was moving along like it should have, and then I had pain, cramping, and nausea. We were in Denver on vacation, so went in to the hospital. They did a CT, saw the blockage, put in a NG to help drain, and gave me gastrograffin thru the NG, this is a dye for X-rays, but also an oily type laxative, within an hour, things were moving. No more lettuce for me. I have had a few near misses with bowel obstructions over the years, and usually, lots of fluid, especially warm fluids, walking, simethicone, and a heating pad have made things better. I suppose as me and my pouch get older, there is more scar tissue, etc. I am pretty careful about what I eat, I eat meat, but it has to be tender and small pieces, try to drink a lot of fluids all day, and have to stay away from anything fiberous or tough.
