The clinical presentation of diverticulitis depends on the location of the affected diverticulum, the severity of the inflammatory process, and the presence of complications.
- Nausea and vomiting
- Constipation, diarrhea, flatulence, and bloating is usually seen
Symptoms of mild diverticulitis may be confused with overlapping symptoms of irritable bowel syndrome.
A microperforation, most likely walled off by adjacent structures, may present with no systemic signs of illness or infection.
Alternatively, disease may progress from a localized and walled-off process to one with peridiverticular inflammatory phlegmon and localized abscess.
