What type of diet would a patient with diverticulitis follow high residual?

Acute Diverticulitis symptoms are similar to other inflammatory bowel conditions, but the location of the symptoms is different from other GI issues (Ulcerative Colitis, Crohn’s, etc.). Typically, diverticulitis will present in the lower left abdomen, while other GI conditions cause more widespread pain. Symptoms of Acute Diverticulitis include:

  • Pain in the lower left abdomen that persists for several days
  • Nausea
  • Vomiting
  • Fever
  • Abdominal tenderness
  • Constipation

Perforated Diverticulitis

Perforated Diverticulitis symptoms are similar to an acute Diverticulitis attack, only worse. Additional symptoms include an indication of sepsis, which is a severe bodily infection. Symptoms of perforated Diverticulitis are listed below:

  • Increased abdominal pain/tenderness
  • Rapid pulse
  • Rapid breathing
  • Fever/chills
  • Decreased urination
  • Diarrhea
  • Nausea/vomiting
  • Difficulty breathing
  • Very low body temperature

If your Diverticulitis symptoms worsen or you experience 3 or more of the above symptoms at once, contact your doctor.

Will I ever be able to eat my favorite foods again?

Yes, you should be able to. Unless you have an extreme condition, your GI system should be able to tolerate most foods within a few weeks after a flare-up or "attack".

You may choose to avoid foods that cause severe issues for your body, such as whole intact seeds. Your diverticulitis diet should always feel as though you are in control of your routine and your food choices.

Sometimes, especially as they get older, people can develop little bulging pouches in the lining of the large intestine. These are called diverticula, and the condition is known as diverticulosis.

When the pouches become inflamed or infected, it leads to a sometimes very painful condition called diverticulitis. In addition to having abdominal pain, people with diverticulitis may experience nausea, vomiting, bloating, fever, constipation, or diarrhea.

Many experts believe that a low-fiber diet can lead to diverticulosis and diverticulitis. This may be why people in Asia and Africa, where the diet tends to be higher in fiber, have a very low incidence of the condition.

Diverticulosis usually causes no or few symptoms; leaving many people unaware that they even have diverticula present.

Diverticulitis may need to be treated with antibiotics or, in severe cases, surgery.

Diet for Diverticulitis

If you're experiencing severe symptoms from diverticulitis, your doctor may recommend a liquid diverticulitis diet as part of your treatment, which can include:

  • Water
  • Fruit juices
  • Broth
  • Ice pops

Gradually you can ease back into a regular diet. Your doctor may advise you to start with low-fiber foods (white bread, meat, poultry, fish, eggs, and dairy products) before introducing high-fiber foods.

Fiber softens and adds bulk to stools, helping them pass more easily through the colon. It also reduces pressure in the digestive tract.

Many studies show that eating fiber-rich foods can help control diverticular symptoms. Women younger than 51 should aim for 25 grams of fiber daily. Men younger than 51 should aim for 38 grams of fiber daily. Women 51 and older should get 21 grams daily. Men 51 and older should get 30 grams daily.  

Here are a few fiber-rich foods to include in meals:

  • Whole-grain breads, pastas, and cereals
  • Beans (kidney beans and black beans, for example)
  • Fresh fruits (apples, pears, prunes)
  • Vegetables (squash, potatoes, peas, spinach)

If you're having difficulty structuring a diet on your own, consult your doctor or a dietitian. They can set up a meal plan that works for you.

Your doctor may also recommend a fiber supplement, such as psyllium (Metamucil) or methylcellulose (Citrucel) one to three times a day. Drinking enough water and other fluids throughout the day will also help prevent constipation.

Foods to Avoid With Diverticulitis

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. However, recent research has noted that there is no real scientific evidence to back up this recommendation.

In fact, nuts and seeds are components of many high-fiber foods, which are recommended for people with diverticular disease.

What kind of diet leads to diverticulitis?

According to a 2018 research article , eating a diet high in red and processed meats could increase your risk of developing diverticulitis. A diet high in fruits, vegetables, and whole grains may decrease the risk.

Should you eat high fiber or low fiber with diverticulitis?

While a diet high in fiber may help prevent diverticulosis and thus diverticulitis; a diet low in fiber may help reduce GI discomfort during flares of diverticulitis by reducing frequency of stools. While with Diverticulitis: Follow a low fiber diet (usually 10-15 grams of fiber per day) until your flares subside.
