Here’s a clear breakdown of what those terms mean and the real symptoms doctors look for.
What is it?
Diverticulosis
This is when small pouches (diverticula) form in the wall of the colon.

- Common with age
- Many people don’t even know they have it
Diverticulitis
This is when those pouches become inflamed or infected. This is the painful condition people usually talk about.
6 common signs of diverticulitis

Key point
- Diverticulosis = pouches (usually harmless)
- Diverticulitis = inflamed/infected pouches (can be serious)
