Generally excellent. 70-80% of people with diverticulosis never develop symptoms. 10-25% develop diverticulitis. 5-15% experience bleeding. Low-fiber diet increases risk of progression. Most people live normal lives with appropriate dietary modifications.

• Adequate hydration
• Regular physical activity
• Maintain healthy weight
