How does diet and lifestyle affect diverticular disease? 

Diet and lifestyle habits may play a role in the management of diverticular disease. Research shows that the following may help reduce symptoms of diverticular disease and decrease the risk of developing complications like diverticulitis or diverticular bleeding:  

• Increasing fiber in the diet
• Mediterranean diet (e.g., plant-based foods like whole grains, vegetables,legumesand fruits) 
• Weight reduction
• Exercise or physical activity
• Avoiding non-steroidal anti-inflammatory drugs(except low dose aspirin which is fine to take)
• Avoiding opiates

Contrary to popular belief, certain foods such as seeds, corn and nuts need not be avoided with diverticulosis.

The following may increase the risk of developing symptoms of diverticular disease and complications like diverticulitis or diverticular bleeding: 

• Obesity
• Smoking
• Excessive red meat (e.g., more than 3 portions per week)
