What is diverticulitis?

Diverticulitis is a condition that affects the digestive tract , causing inflamed sac-like formations in the lining of the gut, these formations are called diverticula. Diverticula develop when the weak points in the intestinal wall give way under pressure, which leads to protrusion of areas.

When diverticula develop, the condition is called diverticulosis, which is a chronic disease . When diverticula become inflamed or infected, the condition is called diverticulitis.

The incidence of diverticulosis increases with age. Less than 5% of people with diverticulosis develop diverticulitis. Diverticulitis can lead to health problems or complications , which include:

  • Nausea;
  • Fever;
  • Severe abdominal pain;
  • Blood in the stool;
  • Abscess;
  • Fistula

What foods should be avoided during an acute attack of diverticulitis?

Some studies show that avoiding some foods and eating others can help with diverticulitis. According to previous studies, the most beneficial condition is following a low-fiber diet and a diet that includes only fluids during the exacerbation of diverticulitis. The diet is specific to each patient, it is good for the specialist to determine exactly which eating strategy is appropriate for a given patient.

Some experts recommend a diet that includes only fluids during mild seizures . Once symptoms improve, patients can switch to a low-fiber diet until symptoms disappear. In the past, recommendations for people with diverticulitis have been to follow a low-fiber diet. But more recent studies show that fiber can reduce the symptoms of diverticular disease and improve bowel function.

Studies show that this is because fiber can improve colon health by allowing stools to move better and favoring the conditions for more beneficial bacteria in the gut, as well as helping to limit weight gain over time. of time.

In the presence of diverticulosis or when the patient has had diverticulitis in the past, dietary recommendations are different from dietary recommendations during an attack.


 Foods containing short-chain carbohydrates

A low-carb diet (which reduces fermentation and flatulence in the colon) has benefits for people with irritable bowel syndrome and may help some people with diverticulitis. Short-chain carbohydrates are fermentable oligosaccharides, disaccharides, monosaccharides and polyols.

Some studies show that a low -carb diet containing short-chain carbohydrates can prevent high blood pressure in the colon, which could theoretically help people avoid or improve their diverticulitis. Examples of foods to avoid are:

  • Some fruits, such as apples, pears and plums;
  • Dairy foods, fresh milk, yogurt and ice cream;
  • Sauerkraut;
  • Bob;
  • Cabbage;
  • Brussels sprouts;
  • Onions and garlic
  • Red meat

Foods high in sugar and fat

A standard diet high in fat and sugar and low in fiber may be associated with an increased incidence of diverticulitis. Studies show that avoiding the following foods can help prevent diverticulitis or reduce its symptoms:

  • Refined cereals;
  • Whole milk products;
  • Fried foods;

Doctors have recommended avoiding nuts, popcorn and most seeds, and the theory is that small particles of these foods can get stuck in bag-like formations and cause infection.


Some older studies also report that people with diverticulitis should avoid alcohol .
