Diverticulosis vs Diverticulitis
| Term | Meaning |
|---|---|
| Diverticulosis | Presence of small pouches (diverticula) in the colon wall — usually silent, found incidentally |
| Diverticular disease | Diverticulosis with symptoms (bloating, altered bowel habit, mild pain) |
| Diverticulitis | Infection/inflammation of diverticula — causes acute pain, fever, needs treatment |
Diverticulitis Symptoms
- Left lower abdominal pain (most common location)
- Fever
- Nausea, reduced appetite
- Change in bowel habit
- Tenderness on examination
Treatment by Severity
| Severity | Treatment |
|---|---|
| Mild (uncomplicated) | Oral antibiotics, liquid diet initially, outpatient management often possible |
| Moderate | Hospital admission, IV antibiotics |
| Complicated (abscess, perforation) | IV antibiotics, drainage procedures, sometimes emergency surgery |
| Recurrent severe episodes | Elective surgery (colectomy) may be considered |
Signs of Complicated DiverticulitisSevere pain, high fever, signs of peritonitis (rigid abdomen), or inability to pass stool/wind require emergency assessment — complications like abscess or perforation need urgent treatment.
Diet and PreventionA high-fibre diet (fruits, vegetables, whole grains) is recommended for diverticulosis to prevent progression and reduce diverticulitis risk — contrary to old advice, nuts and seeds do NOT need to be avoided.
Do I need to avoid nuts and seeds if I have diverticulosis?
No — this old advice has been disproven by modern studies; nuts, seeds, and popcorn do not increase diverticulitis risk and don't need to be avoided.
Will I need surgery for diverticular disease?
Most people manage well with diet and, when needed, antibiotics. Surgery is reserved for complications or recurrent severe episodes significantly affecting quality of life.
