Bottoms

Can’t really help I’m afraid as I do have diverticular but have never in over 10 years had an attack of diverticulitis...

I know 2 people who also have that condition one was hospitalised,and they were advised to not drink fizzy pop,keep away from white bread/biscuits.processed foods etc.
Hope that helps Ngaio1.

broccolli and cauliflower too. Take trousers/pants if lessens your anxiety as anxiety might be exasperating it a bit x

Find out - maybe by bitter experience - what foods are likely to exacerbate the condition, and be careful to avoid them. I recently discovered that an overdose of mushrooms had an unfortunate effect and I avoid spinach which is no hardship as I have always hated it.

Smaller regular meals ?

If you are concerned about small leakages (when passing wind for example), then something like the M&S period pants are helpful. Just like ordinary pants to wear and give you more confidence, but absorbent enough for small accidents, and a spare pair in your bag to change if necessary. They are great for small urine leaks too.

Obviously, do all you can by GP advice and diet wise to reduce the problem.
