So you’ve had a colonscopy and found out you have diverticulosis. Your doctor prescribed Benefiber, then left the room and never returned. Now what? Will you have this forever? Are you unhealthy? How does one develop diverticulosis? And what is the difference between “osis” and “itis?”
By age 60, half of the people in North America will have diverticulosis. By the time they reach 80, this number mushrooms to two-thirds. A diverticulum is a bulge of the inner colon lining through the colon’s muscular wallto its outer surface. A diverticulum looks like a small soap bubble and is only 1/5 to 2/5 inches (0.5-1 cm) in diameter.
If you’ve been eating a diet devoid of fibrous foods, then someday soon you also will be welcomed to the world of diverticulosis. Too many foods today are refined – lacking enough fibre to effectively sweep out the colon and keep it clean. This is especially true of grains, where we throw away the bran – the outer coat. In countries where 100% whole grains are used, diverticulosis is a rarity.
“Diverticulosis has been considered a degenerative disorder in the past. However, there is compelling evidence that, in many patients, it develops as a result of longstanding irritable bowel syndrome: chronic constipation; alternating constipation and diarrhea; abdominal cramps and tenderness; mucus; abdominal bloating and gas; incomplete evacuation; etc. Many patients with diverticulosis have, unfortunately, been the recipients of bad advice regarding their diets. In many cases, high fiber foods have been severely restricted, only making the condition worse. I would submit that most of the symptoms of diverticulosis are actually symptoms of spastic colon/irritable bowel syndrome and are particularly aggravated by fatty foods and emotional stress.

Bran and other fibre hold water in undigested food, making stools soft. Without sufficient fibre, undigested foods become hard and dry, causing the colon walls to strain to keep the matter moving. In some, the diverticulum breaks and causes a local infection in the colon. This condition is called diverticulitis, with subsequent pain in the lower left corner of the abdomen. Sometimes there is also an accompanying fever and chills.
“This picture shows small ulcerations in the colon representing inflammation. The two most common types of colitis we encounter are ulcerative colitis and Crohn’s disease. The more difficult of these two to treat is Crohn’s as it may involve the small bowel as well as the large intestine.There is an increased risk of colon cancer with longstanding (10-20 years) ulcerative colitis and to a slight degree with Crohn’s.” (www.drmarkbowles.com). So practice prevention today! Eat at least 30 grams of fibre daily, consisting of fruits with edible skins, vegetables and whole grain products such as oatmeal, 100% whole grains, baked flatbreads such as Ryvita and brown rice.
