Colonic diverticulitis

At a Glance

Diverticulitis is a condition where inflammation occurs in one or more diverticula of the colon wall, and it is distinguished from diverticulosis.

Representative symptoms may include sudden-onset lower abdominal pain, fever and chills, nausea or vomiting, and constipation or diarrhea.

How the Disease Works

The exact cause has not been established, but genetic predisposition, low-fiber/high-red meat diet, lack of physical activity, obesity, smoking, and certain medications are mentioned as related factors.

As inflammation or infection occurs in the diverticula, an inflammatory response in the surrounding tissues may appear, and possible related mechanisms being studied include intestinal bacteria, stasis of feces, and changes in gut microbiota.

Patterns Vary by Person

The possibility of occurrence and the course of the disease may vary for each individual depending on age, genetic background, dietary and activity habits, smoking, obesity, and drug exposure.

Broad framework of diagnosis and management

Diverticulitis can present acutely, and in some cases, complications such as abscess, fistula, intestinal obstruction, perforation, or peritonitis may occur.

Diagnosis is made by comprehensively combining results from blood tests, stool tests, and imaging studies such as CT, ultrasound, and MRI based on medical history and physical examination, and colonoscopy is considered if necessary.

Current stage of treatment

Since diverticulitis cannot be confirmed by abdominal pain alone, the location and intensity of the pain, presence of fever, test results, and the possibility of other abdominal diseases must be interpreted together.

Management involves choosing between home treatment or inpatient treatment depending on the severity of symptoms and the risk of complications; if necessary, dietary adjustments and procedures or surgery are considered together.

Diverticulitis without complications can be treated conservatively depending on the condition, but if it is severe, accompanied by complications, or does not improve with treatment, inpatient treatment and surgery may be considered.

How to read clinical trials

Since the effectiveness of treatment or adherence to standard care cannot be determined solely by the registration status or completion of diverticulitis-related studies, the study design, disclosure of results, and the participant population must be checked separately.

Points to verify in clinical encounters

During medical consultation, confirm with medical professionals the location and onset of pain, fever, vomiting, changes in bowel movements, history of past diverticulitis attacks and surgeries, current medications, and warning signs of complications; if urgent symptoms such as severe pain or decreased consciousness occur, immediate assistance from the local emergency medical system or medical professionals must be sought.
