What is the correct definition of diverticular disease?

Diverticular disease is accurately defined as a condition that encompasses both diverticulosis and diverticulitis. Diverticulosis refers to the presence of diverticula, which are small bulging pouches that can form in the lining of the digestive system, particularly in the colon. On the other hand, diverticulitis occurs when these pouches become inflamed or infected, leading to various symptoms such as abdominal pain and changes in bowel habits. This terminology helps provide a comprehensive understanding of the spectrum of conditions that fall under diverticular disease, capturing both the asymptomatic and symptomatic phases. Understanding this dual nature is crucial for effective diagnosis and treatment in clinical practice.
