The difference between diverticular disease and diverticulitis is that diverticular disease is a condition where small pouches, called diverticula, form in the wall of the large intestine, while diverticulitis is an inflammation or infection of one or more of these pouches.
Diverticular disease can range from asymptomatic to mild symptoms, such as bloating, abdominal discomfort, and constipation. It is usually diagnosed with a physical exam, barium X-ray, or a colonoscopy. Treatment is typically focused on lifestyle changes, such as increasing fiber intake and using laxatives to maintain regular bowel movements.
Diverticulitis is a more serious complication of diverticular disease and is caused by bacteria that accumulate in the diverticula. Symptoms of diverticulitis may include abdominal pain, fever, nausea, and vomiting. Treatment may include antibiotics, a liquid diet, pain relievers, and rest. In some cases, surgery may be necessary to remove the infected diverticula or to repair a tear in the colon wall.
Overall, diverticular disease is a condition where small pouches form in the wall of the large intestine, while diverticulitis is an inflammation or infection of one or more of these pouches. Treatment for both conditions can vary, but lifestyle changes and medical intervention are often necessary.
