Diverticulosis is a condition where small pouches, called diverticula, form in the wall of the colon (large intestine). These pouches develop when weak spots in the colon wall bulge outward. It is more common in people over the age of 40 and typically occurs without any symptoms.  When diverticula become inflamed or infected, it leads to a more severe condition called diverticulitis, which can cause more noticeable symptoms such as abdominal pain, fever, and changes in bowel movements.  Diverticulosis can also lead to brisk GI bleed. Both of these complications require medical attention. Best way to prevent diverticulosis is eating diet rich in fiber: fruits (apples, pears, berries), vegetables (broccoli, carrots, spinach), legumes (beans, lentils, peas), whole grains.  Drink plenty of water to help fiber move through the digestive system smoothly.  Avoid excessive straining during bowel movements, which can put pressure on the colon walls.  An average adult needs about 25-30 grams of fiber per day.  Most adults only get 10-15 g/day in their routine diet.  There are many OTC fiber supplements available, e.g. Citrucel which has primarily insoluble fiber, which is necessary for improving gut health to prevent diverticulosis.
