Does she currently do any type of maintenance to keep things moving (i.e. Miralax)? I also have a lot of issues with DIOS. I just got out of the hospital for an obstruction a couple weeks ago, and it was the worst one yet. I regularly take Miralax, and when I feel things starting to get backed up, I up the Miralax or I drink a jug of Golytely. And drink LOTS of water! Another cause of obstructions is not drinking enough. Hopefully she sees a GI specialist for her CF-related issues as well. I am so thankful that I got a gastroenterologist who is well-educated in CF. He may be starting me on a prescription medication (I forget the name of it right now) to help prevent some of the obstruction issues. It's another med that draws water to the bowels. DIOS is quite painful (I equate an obstruction to pregnancy contractions)...so anything to prevent it from happening is a blessing. Take care.
