I've found that my diet restrictions change drastically on an (almost) daily basis! So frustrating, and confusing for friends and family who try to understand this darn disease
Really, diet is so individualized that there is no list of safe food for all. I can tell you that prior to my resection, when my scar tissue/inflammation was so bad, I was eating just chicken broth, coffee, processed mac and cheese (the blue box!), and ramen noodles. It was pretty much a liquid diet with some mushy pasta and noodles thrown in so I had something to chew!
Since my resection, there are times when I can't eat any fresh veggies or fruit, salad, nuts, popcorn, red meat, etc. Think anything hard to digest. Right this second, I can do anything in small doses except now I'm not tolerating lactose.
Overly processed food has always been best for me but of course, bad on the waistline! Mashed potatoes, pasta, breads, etc.
Does he obstruct? Or have pain? Or run to the bathroom? Are you sure he's still in remission and this is just scar tissue and it's not an inflammation thing going on?
It's so frustrating, I know. I'm sorry
