Diverticulitis and constipation

First, to say, thank you all for being here for support and helping make sense of things! I was diagnosed with diverticulitis last November, have been fine since January, and am trying to make sense what seems to be divergent views from drs. When I was flaring Nov/Dec 2023, the GI drs (saw both in the practice) said I couldn't make the flare worse or better with particular foods; I could eat whatever I wanted. They said, if I was constipated, certain foods would cause pain, but again, wouldn't alter the progression of the disease. The docs in this practice very firmly believe prohibitions against foods are wrong; they believe studies bear this out. More recently, my primary dr - an internist - has said something very different. (I think.) She says to avoid constipation at all costs, that little bits of fecal matter (She called them fecalites. No idea how it's spelled) trapped in the pockets set flares in motion. So food does matter, but I believe, to her way of thinking, it's only those foods that would promote constipation.

What do your docs say? Thanks so much for sharing your wisdom and experience. Much, much appreciated.
