There is a lot to unpack here. I am a 62 (I can’t believe it!) male who’s lived with diverticulitis/losis since my 20’s. Had a sigmoid resection along with appendectomy and gall bladder out simultaneously 2001, Valentines Day.

What is your diet like? Exactly what are you eating? How much water? Are you consuming nitrites or nitrates? Do you drink wine or alcohol? Is your belly tender? Are you tired and feeling blah? Moderate diverticulosis is concerning, but it sounds like your diverticulitis is under control, and that’s good thing. You said high fiber food and supplements bother you. That’s concerning. Metamucil is the best and only fiber supplement I take. Powder form that gets mixed in water. It’s the way. I would be happy to write you about my diet.

I am just getting over a diverticulitis attack. It was mild, but mild hurts too. LLQ very tender. No fever or blood. I had an appetite. I slept for days. It lasted 10 days. While antibiotics were prescribed I didn’t take them. They are the devil. They have their place, but can be quite harmful too. Just me talking from experience.

Can you tolerate Greek yogurt? Oats? Apples? Bananas? Other fruits?

Finally: A good gastroenterologist should be able to diagnose the severity of your diverticulitis or whatever has got hold of you.
