I have had IBS-C issues for as long as I can remember, but about 7 years ago they became chronic to the point where I can go a week (or more) without any bowel movement if I'm not taking laxatives. I have had dozens of tests, and the only useful information I have received so far was from a visit to the Mayo clinic in Rochester a little over a year ago, where they discovered I have a "highly tortuous colon" and could barely complete a colonoscopy. The recommendations at that time included increasing my fiber, which doesn't help at all. Other tests have also revealed that I have a partially prolapsed lower colon, but not to the point where surgery would be a good idea. Taking fiber supplements makes me extremely bloated and becomes unbelievably painful, and Miralax makes me sick to my stomach and doesn't do too much to move things along. I've tried different things with my diet, and right now, I mostly eat white rice (brown is too hard to digest), vegetables, and small amounts of protein. I feel like i'm going a little crazy trying different things like eliminating dairy or other food restrictions, but I don't know what else to do. I completely avoid gluten. I've been very active my whole life…have run marathons and done lots of strength training and different types of endurance races, but recently I don't have the energy for the types of training that these events require. @karena65 Do you have a resource that you can share on the whole plant diet? Is there any other advice anyone can share?
