So sorry to hear about your diagnosis. I don't have any experience with this, but just wanted to say that I know this is likely not an easy thing to hear. Has your doctor recommended to address it with surgery or are you working to manage it with diet?
What is interesting about this is that you had no symptoms prior to finding out you had it. :>) Typically this is not dangerous for people who have it and there is no direct evidence that it causes constipation. But you are having it. How long ago was your colonoscopy? Since you had no symptoms prior, this could be the after affects to the colposcopy. I have a son with chronic constipation such as one suffers with redundant colon when they do have symptoms. Suggestion for him from the emergency room was to drink one cup of grape juice a day. This keeps his bowels moving. Since you have a bit longer extension and curve (likely) to your large intestines, this may help you keep it all moving. Try it and see if it helps. good luck
