For my mother, keeping stool soft helped with a colon that was narrowed by diverticulitis and scarring. I will say though that when her assisted living missed two nights of stool softener, she had a total blockage and had to have surgery. This may not be relevant.

If you have imaging reports or any other way to find out how much narrowing has occurred that might be helpful.

Personally, I always go with the most gentle, benign approach until a more aggressive one is obviously needed. I think of the term "slow medicine."

I had a similar divergence of opinion about my infrequent afib: do nothing vs blood thinners and other meds- 10 years ago. Doing nothing has certainly proven to be the wise course.

You can always get another opinion to be a tie breaker!
