While the cause of diverticular diseases is unknown, several studies have associated the conditions with low fiber intake, excessive alcohol use, anti-inflammatory medications, steroids, obesity, lack of exercise, and smoking.

Why do I keep getting diverticulitis flare-ups?

Lifestyle remains the major culprit behind diverticulitis flare-ups. A high-fat, low-fiber diet commonly followed in Western countries can exacerbate diverticulitis symptoms. Lack of fiber in the diet can cause constipation and strain the bowel.

What are the trigger foods for diverticulitis?

Actually, no specific foods are known to trigger diverticulitis attacks. And no special diet has been proved to prevent attacks. In the past, people with small pouches (diverticula) in the lining of the colon were told to avoid nuts, seeds and popcorn.
