Overview

Diverticulitis occurs when small, bulging pouches within the digestive tract become infected or inflamed. Called diverticula, these pouches form when naturally weak areas in the colon give way to pressure and create small pockets that protrude through the colon wall. Usually, these pouches go relatively unnoticed; however, when they tear due to inflammation or infection, serious pain and complications can occur.

What Are the Symptoms of Diverticulitis?

There are several symptoms that point toward diverticulitis. These include:

  • Persistent abdominal pain, usually within the lower left side of the belly
  • Abdominal tenderness
  • Elevated heart rate
  • Fatigue
  • Fever or chills
  • Nausea and vomiting
  • Constipation
  • Bloating
  • Diarrhea
  • Rectal bleeding
  • Blood in stool

Symptoms may occur suddenly or gradually over the course of a few days.

How is Diverticulitis Diagnosed and Treated?

Diagnosis is determined based on a person’s symptoms and medical history and may include blood tests or a CT scan of the abdomen and pelvis.

Treatments depend on the severity of each case. For uncomplicated diverticulitis, the following approaches may be recommended:

  • Antibiotics
  • A liquid diet until your bowl heals
  • Over-the-counter pain relievers

Severe cases of diverticulitis demand more aggressive treatments, including:

  • Hospitalization
  • Intravenous antibiotics
  • Insertion of a tube to drain potential abscesses
  • Surgery

In some instances, severe diverticulitis may require surgery. This is usually due to complications such as an abscess, bowel obstruction, fistula, or perforation. Depending on the amount of inflammation, patients may require a minimally invasive laparoscopic procedure or an open surgery involving a bowel resection with colostomy.

Early detection can go a long way toward avoiding the need for surgery, so promptly visit your doctor or go to an urgent care center if you exhibit any troubling symptoms. It’s especially important to seek urgent medical care if abdominal pain occurs alongside fever and diarrhea or constipation.
