The first few days of a diverticulitis diet may be limited to clear liquids, including broth, fruit juices, water, tea and coffee, according to the Mayo Clinic. Low-fiber foods such as cooked fruits and vegetables, eggs, white bread, white rice or noodles are added back into the diet gradually.
Diverticulitis can't be prevented through diet, but a liquid diet allows the digestive system a chance to rest, according to the Mayo Clinic. Diverticulitis is a condition in which diverticula, which are small pouches in the digestive tract, become infected or inflamed. Antibiotics are often prescribed in tandem with diet restrictions for mild cases of diverticulitis. In severe cases, hospitalization may be required.
Patients generally start to improve after two to three days of starting treatment, states the Mayo Clinic. Signs of complications include fever, abdominal pain, vomiting or regurgitating liquid. There are few risks with a diverticulitis diet, but weakness can occur if a liquid diet extends beyond a few days. Nutrients from food sources are essential, and transitioning back to a normal diet should occur as soon as the patient can tolerate it.
As high-fiber foods are reintroduced into the diet, patients should strive for 25 to 35 grams of fiber per day and drink plenty of water, according to WebMD. Fiber helps to soften stool, reducing pressure and allowing it to pass easily through the digestive tract. High-fiber foods include whole grains, beans, vegetables and fruits. A doctor may also prescribe a fiber supplement as needed.
