I've had all the symptoms that this brings on, but just had the dx of redundant colon with my colonoscopy earlier this week. Never before has this come up with any other CT scans in the past few years and another colonoscopy back in '19. Right upper abdominal pain and clinching to the point of where it feels like a softball is inside me. Every CT scan I have had show excessive stool in my system even though I've taken linzess, and OTC motility supplements, and adhere to a low fat/low sugar diet. Similar to others here, that jammed up feeling then kicks off the feeling like crap , and not being able to go #2. My bile duct has been detached from the stomach and reattached to the small intestine to avoid the excessive bile that was building up in my stomach, hence having the surgery back in late '19.
