Symptoms of Diverticulitis

Diverticula are small sacs that bulge outward through weak spots in the wall of the colon, often in the lower section. When these pouches form, the condition is called diverticulosis. Most people with diverticulosis experience no symptoms. But when the pouches become inflamed or infected, it progresses to diverticulitis — a more serious condition that can cause sudden complications.

Recognizing the signs of diverticulitis is key to getting timely treatment and preventing further issues.

1. Understanding diverticulitis

Diverticula can form as a natural side effect of aging. Years of bowel strain from constipation or other issues can weaken the colon’s lining, allowing parts of it to bulge outward — a condition known as diverticulosis. While most adults over 60 have these pouches without symptoms, trouble begins when a pouch becomes blocked or filled with stool. This can create the perfect environment for bacteria to grow, leading to infection and inflammation. Though the exact cause of diverticular disease isn’t fully understood, experts believe it likely stems from a combination of factors, including diets high in red meat and low in fiber, obesity, smoking, physical inactivity, and certain medications such as NSAIDs or steroids.
