Which of these statements about diverticular disease is true?

Diverticulosis is accurately defined as the presence of diverticula, which are small pouches that develop in the walls of the colon, without any accompanying inflammation. This condition often arises from a combination of factors, most notably a low-fiber diet, leading to increased pressure within the colon as stool becomes harder to pass. In contrast, diverticulitis occurs when these diverticula become inflamed, which can lead to complications such as infections or other serious conditions.

Recognizing that diverticulosis itself does not involve inflammation is critical for understanding the overall spectrum of diverticular disease. It emphasizes the importance of preventive measures, such as adopting a high-fiber diet, to avoid the progression to diverticulitis. Other options in the question misrepresent aspects of diverticular disease, such as conflating the severity and implications of diverticulosis with those of other forms like diverticulitis. Understanding the distinction between these states is essential for appropriate management and patient education.
