fiber at this point is going to make your pain worse so i would lay off of it for at least a week or two. he did say diverticulitis right and not diverticulosis? polyps are precursors to cancer. they dont cut you open, they stick a camera up your ass and snip them off yeah dont eat fiber at this point. try to keep it less than 15 grams a day. when the diverticula are healed (called diverticulosis), typically 1-2 weeks, then you can up your fiber to 25-35 grams a day. i am not opposed to fiber supplements but try to get it the natural way through fruits, veggies and whole grains. make sure you avoid nuts seeds and corn, from here on out...yes that means the rest of your life.
