Diverticulitis

Inflammation of small pouches in the colon that can cause severe abdominal pain and digestive complications

Quick Facts

  • Type: Gastrointestinal Inflammatory Condition
  • ICD-10: K57.9
  • Age Group: More common over 40
  • Severity: Ranges from mild to life-threatening

Overview

Diverticulitis is a potentially serious digestive condition that occurs when small pouches called diverticula, which can form in the walls of the large intestine (colon), become inflamed or infected. These diverticula are small, bulging sacs that can develop anywhere in the digestive system, but are most commonly found in the lower part of the large intestine called the sigmoid colon. While many people develop diverticula as they age (a condition called diverticulosis), diverticulitis specifically refers to the inflammatory complication that affects approximately 10-20% of people with diverticulosis.

The condition typically manifests as sudden onset of severe abdominal pain, most commonly in the lower left side, accompanied by fever, nausea, and changes in bowel habits. Diverticulitis can range from mild inflammation that may resolve with conservative treatment to severe complications requiring emergency surgery. The inflammation occurs when waste matter gets trapped in the diverticula, leading to bacterial overgrowth and subsequent infection. This can result in various complications including abscess formation, perforation of the bowel wall, bleeding, or the development of fistulas connecting the colon to other organs.

The incidence of diverticulitis has been increasing significantly in Western countries, likely due to dietary factors, aging populations, and lifestyle changes. It primarily affects older adults, with the risk increasing substantially after age 40, though younger people can also develop the condition. The disease pattern varies geographically, with left-sided disease being more common in Western countries and right-sided disease more prevalent in Asian populations. Understanding diverticulitis is crucial because while mild cases can often be managed with outpatient treatment, severe cases require hospitalization and may lead to life-threatening complications. Early recognition and appropriate management can prevent complications and improve long-term outcomes for patients.
