What’s the difference between diverticulosis and diverticulitis?

Diverticulosis is simply the presence of these tiny bulges or pockets (diverticula) in your colon. They usually don’t cause any symptoms or need to be treated. However, diverticulosis can lead to diverticulitis.

Diverticulitis is inflammation (swelling) and infection in one or more diverticula. You may feel pain, nausea, fever and have other symptoms. This is a much more serious and potentially dangerous condition.
