What Causes Diverticulitis Flare Ups?

Diverticulitis

Diverticulitis occurs when small pouches (diverticula) that can form in the walls of the colon become inflamed or infected. Diverticulitis flare-ups can be triggered by various factors, and the exact cause can vary from person to person. Some common factors that may contribute to diverticulitis flare-ups include:

  • Obstruction of Diverticula: Fecal matter or undigested food particles can become trapped in the diverticula, leading to inflammation and infection.
  • Low-Fiber Diet: A diet low in fiber can contribute to the development of diverticulitis. Insufficient fiber intake can result in hard stools, leading to increased pressure on the colon walls and an increased risk of diverticula formation.
  • Bacterial Overgrowth: Bacterial overgrowth in the diverticula can lead to infection and inflammation. Changes in the balance of bacteria in the colon may contribute to diverticulitis flare-ups.
  • Age: The risk of diverticulitis increases with age. Older adults are more likely to develop diverticula, and the risk of complications, including flare-ups, also increases.
  • Genetic Factors: There may be a genetic component to the development of diverticulitis. If there is a family history of the condition, an individual may be at a higher risk.
  • Lifestyle Factors: Certain lifestyle factors can contribute to diverticulitis flare-ups, including smoking, lack of physical activity, and obesity.
  • Medications: Certain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) and steroids, may increase the risk of diverticulitis or contribute to flare-ups.
  • Prior Episodes: Individuals who have had a previous episode of diverticulitis may be more susceptible to future flare-ups.
  • Immunosuppression: Conditions or medications that suppress the immune system may increase the risk of infections, including diverticulitis.

It’s important to note that diverticulosis (presence of diverticula) itself does not always lead to diverticulitis. Many people with diverticulosis never experience symptoms or complications. However, when diverticulitis occurs, it can cause symptoms such as abdominal pain, fever, and changes in bowel habits.

Management of diverticulitis often involves dietary changes, including increasing fiber intake, staying hydrated, and using medications such as antibiotics in the case of infection. In severe cases or complications, surgical intervention may be necessary. Individuals experiencing symptoms or concerns related to diverticulitis should seek medical attention for proper evaluation and guidance.
