Sigmoid colon stricture due to diverticulosis/diverticulitis

Hi! I’m Marissa. I really appreciate this forum and learn so much from other’s experiences. So my question is this… has anyone ever had a sigmoid colon stricture that they’ve been able to clear up with a diet? I knew that I had diverticulosis, but I also thought I had a spastic colon so throughout the years I would have digestive issues from time to time and even pencil thin stools, but eventually it would clear up. I also have been treated for hypo thyroid since 1995. However, I knew something wasn’t right, and in September with my annual thyroid exam found my thyroid to be way out of whack, even though I was taking my medication’s as I always had. I feel it basically shut down the function of everything, so I was taking Metamucil and collagen and doing fine, but i did make and appt with GI doc and made appt for colonoscopy in January.

Then, in late December, I experienced what I believe to be a flareup of diverticulitis. I just powered through it not really knowing what it was and didn’t get any treatment. Then mid January I had another one which was excruciating, but after a couple days of clear liquids, and knowing I had an upcoming colonoscopy, I again got no treatment. Please keep in mind that i only assumed this was diverticulitis from looking up symptoms and knowing i had diverticula from colonoscopy in 2006. On January 22 I had my colonoscopy. The doctor said it was extremely difficult and I had severe severe diverticulosis with structure. He had to go to the smallest scope available to complete the colonoscopy. (Smaller than the pedi scope)! he then told me to eat high fiber, which I jumped into wholeheartedly eating about 20 to 25 g of fiber a day and trying to exercise 30 minutes 2 to 3 times a week. I’m also taking MiraLAX every morning and magnesium citrate every evening. This allows me to have a stool every day, but it is all pencil thin and I feel inflammation in my abdomen. I am wondering if I should turn to a low residue diet or something similar for a time to try to allow my bowel to rest? I don’t want to jump directly to surgery as this seems so sudden. Does anyone have any experience or thoughts on this? Thank you in advance!!!
