Diverticular Disease & Diverticulitis
Attacks, CT diagnosis, antibiotics, and elective resection
Elective surgery is not automatic after “the third attack.”
Diverticulosis is common with aging; diverticulitis is inflammation of a diverticulum — this hub is separate from IBD (Crohn’s / ulcerative colitis). CT guides severity and separates mild from complicated disease (abscess, perforation, fistula, obstruction). Uncomplicated mild attacks may not need automatic antibiotics in selected patients. Elective resection is driven by complications, quality of life, immunosuppression, and preference — not attack count alone. Colonoscopy timing after inflammation depends on whether a recent high-quality exam already exists. Emergency surgery remains necessary for selected free perforations and unstable patients.

CT staging
Separates mild from complicated disease.
Antibiotics
Not automatic in every mild uncomplicated case.
Elective surgery
Fistula, stenosis, immunity, lifestyle — not a magic number of attacks.
Colonoscopy timing
Based on recent quality exams, not a rigid ritual.
What to know
- Key note inside
Complicated disease
Abscess, perforation, fistula, or obstruction change urgency and often need drainage, antibiotics, or surgery.
Mild uncomplicated attacks
Selected outpatients may be managed with careful follow-up; automatic antibiotics are no longer assumed for every mild case.
Elective resection
Shared decision after recovery from acute inflammation. Fistula, stricture, smoldering disease, and life impact matter more than “third strike.”
Colonoscopy after diverticulitis
Timing depends on recent high-quality colonoscopy and alarm features — not a one-size calendar for every attack.
Prevention habits
Fiber-forward diet and smoking cessation support bowel health; they do not replace CT evaluation of a severe flare.

Appointment / info
Bring CT reports from prior attacks if available — severity history shapes elective decisions more than memory alone.
