In the past, doctors had recommended that people with diverticular disease (diverticulosis or diverticulitis) avoid hard-to-digest foods such as nuts, corn, popcorn, and seeds, for fear that these foods would get stuck in the diverticula and lead to inflammation.
Actually, no specific foods are known to trigger diverticulitis attacks. And no special diet has been proved to prevent attacks. In the past, people with small pouches (diverticula) in the lining of the colon were told to avoid nuts, seeds and popcorn.
Research suggests that a diet low in fiber and high in red meat may increase your risk of getting diverticulitis—inflammation of one or a few pouches in the wall of your colon. Eating high-fiber foods and eating less red meat may lower the risk.
Mild cases of diverticulitis are usually treated with antibiotics and a low-fiber diet, or treatment may start with a period of rest where you eat nothing by mouth, then start with clear liquids and then move to a low-fiber diet until your condition improves. More-severe cases typically require hospitalization.
You may have heard advice that people with diverticular disease should avoid small, sharp and hard foods such as nuts, seeds and corn. The thinking is that there is a risk of undigested remnants of these foods lodging in the diverticula and causing inflammation.
Stay with liquids or a bland diet (plain rice, bananas, dry toast or crackers, applesauce) until you are feeling better.
Diverticulitis is caused by an infection of one or more of the diverticula. It is thought an infection develops when a hard piece of stool or undigested food gets trapped in one of the pouches. This gives bacteria in the stool the chance to multiply and spread, triggering an infection.
Plus, probiotics have anti-inflammatory effects, which may help to ease inflammation from diverticulitis. Probiotics are available in supplement form, but they can also be found in certain foods, such as yogurt, kombucha, and fermented vegetables.
Eggs contain protein that can be easily digested, and it will not irritate your digestive tract. Therefore, scrambled eggs can be taken during diverticulitis.
Fresh fruits, like apples, have the most fiber when eaten with the skin. 13 However, if you're having symptoms of diverticulitis, look for lower-fiber options, like applesauce. Bananas are another good source of fruit fiber.
There are no specific foods you need to avoid. You do not need to avoid any foods such as nuts, seeds, corn, popcorn or tomatoes if you have diverticular disease. These foods do not make diverticular disease worse. These foods may even help prevent it because they are high fibre choices.
“Eggs are a great source of protein, and they're easily digested,” Dr. Nazarian says. And they won't irritate your diverticula.
In about 95 out of 100 people, uncomplicated diverticulitis goes away on its own within a week. In about 5 out of 100 people, the symptoms stay and treatment is needed. Surgery is only rarely necessary.
Diet and lifestyle
Not eating enough fibre is thought to be linked to developing diverticular disease and diverticulitis. Fibre helps to make your stools softer and larger so they put less pressure on the walls of your intestines. Some other things that seem to increase your risk include: smoking.
Oatmeal is a great source of fiber – which is important for patients with diverticulitis or diverticulosis. But be sure to avoid eating high-fiber foods while experiencing a flare-up or abdominal discomfort.
The diverticulitis flare will usually go away after four to six weeks, Doerfler says. At that point, you can start eating higher-fiber foods like whole grains, fruits and vegetables, and healthy fats like nuts, seeds, avocado, and olive oil.
The most common symptoms of diverticulitis include severe left lower quadrant abdominal pain, marked changes in bowel habits, fever, and nausea. Possible complications include perforation of bowels, abscess formation, fistula formation, obstruction, and bleeding.
A colonoscopy is a helpful tool for diverticular disease. Especially where there are severe symptoms or bleeding that might be from diverticulitis, a colonoscopy might be done right away. Follow-up colonoscopies are usually done after the symptoms of diverticulitis clear up.
Bulk-forming laxatives such as Metamucil or Citrucel may be recommended after the diverticulitis flare-up has resolved. These types of supplements can help add fiber to the diet while treating either constipation or diarrhea.
Water and clear juices (such as apple, cranberry, or grape), strained citrus juices or fruit punch. Coffee or tea (without cream or milk) Clear sports drinks or soft drinks, such as ginger ale, lemon-lime soda, or club soda (no cola or root beer) Clear broth, bouillon, or consommé
