What does diverticulosis mean?
Diverticulosis is the medical term for the presence of diverticula, small pouches that form when the wall of a hollow organ, most commonly the colon, bulges outward. Many people with the condition experience no symptoms, although it can sometimes cause discomfort, changes in bowel habits, or complications. Diverticulosis should not be confused with diverticulitis, which occurs when a diverticulum becomes inflamed and is more likely to produce significant abdominal pain, fever, or nausea. The term is used in clinical settings, diagnostic reports, and discussions of gastrointestinal health, especially in relation to screening and long-term management. Although diverticulosis is common, particularly among older adults, its presence does not by itself establish that a person has diverticulitis. Knowing the distinction is useful because the two conditions have different symptoms, risks, and forms of treatment.

Where does diverticulosis come from?
The word comes from New Latin diverticulosis, a medical formation meaning the condition of having diverticula. Its base is the Latin diverticulum, meaning a small side passage or opening, a diminutive related to divertere, “to turn aside.” The related medical terms diverticulitis, diverticular, and diverticulectomy developed from this same Latin root.
