Causes of diverticulosis

The causes of diverticulosis includes:
• Increased pressure within the intestine. This mainly occurs when the feces are small and hard, and the muscles of the intestine must contract strongly to move them, thus, exerting alot of pressure on its wall.

• When they are certain weak spots within the intestinal wall, it can also cause the formation of diverticuli in the walls of the intestine.

• Fiber rich foods
• Water
• Vegetables
• Legumes
• Whole grains, and
