I looked up tortuous redundant colon and it sounds a lot like Crohn's disease which my son-in-law had when he was about 20 years old. He had a stoma on the side of his abdomen and did very well with it.

No, I don't have that. I'm sorry if that is what you are dealing with. He never complained but later on had short-bowel problems. Lived with it for 50 years. Never complaining about it.
