Treatment of Mild Acute Uncomplicated Colonic Diverticulitis in the Immunocompetent Patient
This protocol addresses the management of mild, acute, uncomplicated colonic diverticulitis in immunocompetent adults — a specific clinical scenario in which the approach to diet and antibiotic use differs from more severe or complicated presentations.
Clinical scenario
The patient is immunocompetent and presents with a mild, acute, uncomplicated episode of colonic diverticulitis. No features of complicated disease are present.
Approach (partial)
Initial management centres on dietary modification during the acute phase, with a structured plan for advancing intake as symptoms resolve. Antibiotic treatment is not given routinely in this setting — its use is selective rather than standard. The complete regimen, including the conditions that guide selective antibiotic use, is in the full protocol.
Clinical goal
Resolution of symptoms sufficient to allow dietary advancement within 3–5 days. Failure to advance diet within this window warrants prompt reassessment.

A clear liquid diet is advised during the acute phase of uncomplicated diverticulitis.
Diet should advance as symptoms improve.
Antibiotic treatment can be used selectively, rather than routinely, in immunocompetent patients with mild uncomplicated diverticulitis.
If a patient is unable to advance their diet after 3–5 days, they should follow-up immediately.
