diverticulosis

This term describes the presence of diverticula without active inflammation. It is a clinical state rather than an acute disease, often remaining asymptomatic for years. It is frequently contrasted with diverticulitis, which refers to the active inflammation or infection of these pouches.

As a medical condition denoting a specific pathological state, the word is uncountable. It refers to the condition as a whole rather than individual instances of the disease, and therefore does not have a plural form.
