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.
As you get older, your colon wall can become weaker. This can cause small pockets or pouches to form in weakened areas of your colon. If these pouches get infected, it can cause a diverticulitis attack or flare-up.
Doctors believe the main cause is a low-fiber diet. Most people with diverticulosis don't have symptoms. Sometimes it causes mild cramps, bloating or constipation. Diverticulosis is often found through tests ordered for something else.
High fiber vegetables such as broccoli, cabbage, and artichokes are high in fiber and can be difficult to digest. Eating them may cause gas and bloating. People with diverticulitis may not digest lactose well.
Some studies suggest that low fiber diets can even increase the risk of diverticulitis, along with high meat intake, low physical activity, and smoking. High fiber foods include: beans and legumes, such as navy beans, chickpeas, lentils, and kidney beans.
Uncomplicated diverticulitis
Your doctor is likely to recommend: Antibiotics to treat infection, although new guidelines state that in very mild cases, they may not be needed. A liquid diet for a few days while your bowel heals. Once your symptoms improve, you can gradually add solid food to your diet.
Stay with liquids or a bland diet (plain rice, bananas, dry toast or crackers, applesauce) until you are feeling better. Then you can return to regular foods and slowly increase the amount of fibre in your diet. Use a heating pad set on low on your belly to relieve mild cramps and pain.
Dairy: “Cottage cheese and Greek yogurt are real winners if you're recovering from a flare-up: They're high in protein, calcium and other nutrients and don't have any fiber. They're also soft, moist and easier to get down if you're not feeling well,” says Taylor.
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
13 However, if you're having symptoms of diverticulitis, look for lower-fiber options, like applesauce. Bananas are another good source of fruit fiber. They also have a lot of potassium and can be especially helpful if you're recovering from a stomach upset.
How long does a diverticulitis flare-up typically last? After starting treatment, most people should start to feel better in two or three days. If symptoms don't start to get better by then, it's time to call a healthcare provider and get instructions on what to do next.
Eat a low-fiber diet. Your healthcare provider may advise a liquid diet. This gives your bowel a chance to rest so that it can recover. Foods to include: flake cereal, mashed potatoes, pancakes, waffles, pasta, white bread, rice, applesauce, bananas, eggs, fish, poultry, tofu, and well-cooked vegetables.
Increase fiber to add bulk to the stool — Fiber can help to bulk up your stool. A high-fiber diet might prevent new diverticula, diverticulitis or diverticular bleeding. Fiber has not proven to prevent these conditions or get rid of current diverticuli. Fruits and vegetables are a good source of fiber.
Once diverticula form, they do not disappear by themselves. Fortunately, most patients with diverticulosis do not have symptoms, and therefore do not need treatment.
It is possible that stress plays a role in the development of diverticulitis as it is estimated that in 60 percent of cases the condition occurs due to environmental causes. Stress on the digestive system commonly experienced because of low fiber diets. Diets high in fat may also cause diverticulitis.
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.
