About this condition
Diverticula are small pockets in the intestinal wall. Diverticulosis means these pockets are present; diverticulitis refers to inflammation. An incidental finding does not automatically require treatment or surgery.
What matters most
The distinction matters because uncomplicated diverticulosis, suspected acute diverticulitis and diverticular bleeding can need very different management. A new severe abdominal pain should not simply be attributed to known diverticula.
Symptoms and reasons to seek help
Some people have no symptoms. Diverticulitis may cause localised lower abdominal pain, fever and bowel changes. Rectal bleeding, increasing pain, fainting or marked abdominal distension are reasons for prompt assessment.
How it differs from similar conditions
Bowel infection, inflammatory bowel disease and other abdominal conditions may produce overlapping symptoms. The presence of diverticula on an old examination does not prove that they are causing current complaints.
Assessment and investigations
History, examination and selected blood tests help evaluate severity. CT may be appropriate when acute diverticulitis or a complication is suspected. Colonoscopy is scheduled according to indication and safety rather than automatically during an acute flare.
Care options and limitations
Management depends on severity, other illnesses and complications. Some cases can be managed without antibiotics, while severe disease needs hospital care. Do not self-prescribe antibiotics or strong laxatives for acute unexplained abdominal pain.
When emergency help is needed
Severe or escalating abdominal pain, a rigid abdomen, fever with a very unwell appearance, significant rectal bleeding, fainting or signs of bowel obstruction needs urgent medical evaluation. Call 103 or 112 for severe symptoms.

Frequently asked questions
Must incidentally found diverticula be removed?
No. Diverticulosis without complications is not an automatic indication for an operation.
Does every episode of diverticulitis need antibiotics?
No. A clinician decides based on severity, underlying risks and possible complications.
Is colonoscopy routinely performed during an acute painful flare?
Not necessarily. The timing and safety of colonoscopy require individual medical assessment.
Important information
A medical consultation is needed for diagnosis and treatment recommendations.
Self-treatment can be harmful to your health.
