I have diverticitis and was wondering what causer it to flare up?

Usually diet: Most americans over 40 have some degree of diverticulosis.Inflammation, or diverticulitis, is frequently caused by diet, such as popcorn hulls or peanuts, etc.Sometimes, it just occurs as some stool is trapped in a diverticulum. During acute episodes, i recommend a low residue diet.When resolved, i encourage a moderate to high fibre diet.Most seeds are ok, but i limit peanuts and popcorn.Good luck.
