People with Diverticulosis tend to have segments of their colon that push out into pouches, called diverticula. When these pouches become inflamed or infected, the condition turns into Diverticulitis. When these pouches get inflamed, they are referred to as flare-ups. These flare-ups can occur suddenly with abdominal pain typically on the left side. Fever, nausea or vomiting may also occur during flare-ups.
Diverticula is often the result of not enough fiber in the diet. As a result, the stool become hard and it gets difficult to pass it through the colon. This pressure on the wall of the colon results in the formation of diverticula.
While a high fiber diet may help prevent diverticulosis and thus diverticulitis, a low fiber (or low residue) diet is often recommended during flare-ups.
What to eat during Diverticulitis:
Usually a low fiber diet, (approximately 10-15 grams of daily fiber) is recommended until the flares recede.
You may want to avoid these foods, especially if you are having problems with diarrhea, or have gas , bloating or cramping:
- Foods that are greasy, fried and high sugar content
- Foods with high amounts of lactose
- Sweetened and caffeinated beverages, including smoothies, fruit juices or sodas with high sugar content
- Foods that contain artificial sweeteners.
