Like you, and many others here, my IBS was also progressive. It started slowly,it came and went, and all of a sudden it was here to stay.Have you tried a stool softener? That may help, I use colace. Start at a lower dose and work your way up until you find a dosage that works. It is safe to take it daily. If you take too high of a dosage at first you will get a lot of cramping.Definitely increase your fiber, some do well with this, others don't, it's worth a shot. I eat FiberOne Honey Clusters in the morning for breakfast, I think that is very helpful. I've also cut out all fatty foods, nothing ever that is fried, very little dairy,no red meat...it's a very restrictive diet but it works for me! You have to find the foods that irritate your system and cut them out. For me it was like introducing solids to my kids. I started with a few foods that I knew wouldn't bother me and added something new every couple of days, just like you do with a baby. It's a long process but you will make your way through it!!Lastly, see a gastroenterologist, one that is supportive of you and your health. If diet, fiber supplements and stool softeners don't work you will need to try other avenues, like Zelnorm or Amitiza...You'll get through it. There is lots of support here from people who are just like you!!Maureen
