So sorry! It takes more than just Miralax or the like to help with the problem of a Tortuous Colon. I’ve suffered with it myself for as long as I can remember. I was told more fiber, fresh fruits & vegetables. That was it and it was after my colonoscopy. Of course, one doctor said I had then he moved. The next doctor said no you don’t. I also have IBS. My colonoscopy have been very difficult for them to do as long as I recall, and often I’d feel the pain while they were doing it! I’m in a new state now, and the GI doctor here says I DEFINITELY have it! So again told me to eat extra fruit and vegetables, and take Citricel or the like. Taking a fiber supplement actually backs me up more! I drink plenty of water too, always have. That isn’t the issue. So I stated just recently really focusing on the types of more seriously. Staying away from dairy, gluten products and processed food for the most part. Are you familiar with the FODMAP. You can try that form of illumination and see what sets you off. I’m really doing great now. I’m eating a lot of raw food when I can. Smaller amounts too. It’s a process for sure! I’m going to get this yet! They tried me on the Linzess and that was really a NASTY medication!! Terrible side effects. I wish you all the best in your search. Maybe a Nutritionist would help?
