Common signs and symptoms of Diverticular Disease include:
When to see a doctor
If you experience severe or worsening symptoms, seek immediate medical attention. Always consult with a healthcare professional for proper diagnosis and treatment.
Causes & Risk Factors
Several factors can contribute to Diverticular Disease.
Diverticular disease develops when pressure inside your colon becomes too high, causing weak spots in the intestinal wall to bulge outward like tiny hernias.
Diverticular disease develops when pressure inside your colon becomes too high, causing weak spots in the intestinal wall to bulge outward like tiny hernias. Think of it like an old garden hose that develops bulges when water pressure gets too strong at vulnerable points. Your colon muscles naturally contract to move waste along, but when this process becomes strained, those little pouches form over time.
The primary culprit behind this increased pressure is a low-fiber diet common in Western countries.
The primary culprit behind this increased pressure is a low-fiber diet common in Western countries. When you don't eat enough fiber, your stool becomes small and hard, forcing your colon muscles to squeeze much harder to move things along. This repeated straining over decades gradually weakens the colon wall and creates those characteristic pouches. Countries with high-fiber traditional diets see much lower rates of diverticular disease.
Once diverticulosis exists, diverticulitis occurs when bacteria and waste get trapped inside these pouches, leading to inflammation and sometimes infection.
Once diverticulosis exists, diverticulitis occurs when bacteria and waste get trapped inside these pouches, leading to inflammation and sometimes infection. Poor blood flow to the area, changes in gut bacteria, and genetic factors that affect tissue strength also contribute to whether someone develops complications. Age plays a role too, as the colon wall naturally becomes less elastic over time, making pouch formation more likely.
Risk Factors
- Age over 40 years
- Low-fiber diet with processed foods
- Lack of regular physical exercise
- Obesity or being overweight
- Smoking cigarettes regularly
- Taking certain medications like steroids or NSAIDs
- Having connective tissue disorders
- Chronic constipation
- Family history of diverticular disease
- Living in Western developed countries
Diagnosis
How healthcare professionals diagnose Diverticular Disease:
- 1
When you visit your doctor with abdominal pain, they'll start by listening to your symptoms and examining your belly, feeling for tender spots and checking for fever.
When you visit your doctor with abdominal pain, they'll start by listening to your symptoms and examining your belly, feeling for tender spots and checking for fever. Your doctor will ask detailed questions about your pain pattern, bowel habits, and diet to distinguish diverticulitis from other conditions that can cause similar symptoms. This initial assessment helps determine how urgently you need testing.
- 2
For suspected diverticulitis, a CT scan of your abdomen and pelvis is usually the first imaging test.
For suspected diverticulitis, a CT scan of your abdomen and pelvis is usually the first imaging test. This scan can show inflamed diverticula, complications like abscesses, and rule out other serious conditions. Blood tests check for signs of infection and inflammation. If you're having severe symptoms, these tests might happen in the emergency room. For milder cases, your family doctor might order outpatient testing.

Colonoscopy, where a flexible camera examines your entire colon, is typically avoided during active diverticulitis because it could worsen inflammation.
Colonoscopy, where a flexible camera examines your entire colon, is typically avoided during active diverticulitis because it could worsen inflammation. However, your doctor might recommend this test several weeks after symptoms resolve to confirm the diagnosis and check for other conditions. Other tests might include:
- 4
- Stool samples to rule out infections - Urine tests to exclude kidney problems
- Stool samples to rule out infections - Urine tests to exclude kidney problems - Ultrasound in some cases - Barium enema (less commonly used now)

Conditions that can mimic diverticulitis include appendicitis, inflammatory bowel disease, irritable bowel syndrome, and even ovarian problems in women.

Complications
- While most people with diverticular disease never experience serious problems, complications can occur, especially with repeated episodes of diverticulitis.
- The most common complication is abscess formation, where pockets of infection develop near inflamed diverticula.
- Small abscesses often heal with antibiotics, but larger ones might require drainage procedures or surgery.
- More serious but less common complications include perforation, where a diverticulum ruptures and spills intestinal contents into the abdominal cavity, potentially causing life-threatening peritonitis.
- Bleeding can occur when blood vessels near diverticula become damaged, sometimes requiring emergency treatment.
- Fistulas, abnormal connections between the colon and other organs, can develop over time.
- Strictures, where scar tissue narrows the colon, might cause bowel obstruction.
- The encouraging reality is that with prompt medical care, most complications can be successfully treated, and many people go on to live normal, healthy lives.
Prevention
- Gradually increasing fiber intake to avoid gas and bloating
- Managing stress through relaxation techniques
- Maintaining a healthy weight
- Not ignoring urges to have bowel movements
- Limiting nuts and seeds if they seem to trigger symptoms (though research shows mixed results on this)
- Getting regular medical check-ups to monitor the condition
Treatment for diverticular disease depends on whether you have simple diverticulosis or active diverticulitis.
Treatment for diverticular disease depends on whether you have simple diverticulosis or active diverticulitis. For uncomplicated diverticulosis that's not causing symptoms, the focus is on preventing progression through dietary changes and lifestyle modifications. Your doctor will likely recommend increasing fiber intake gradually and staying well-hydrated to keep stools soft and reduce colon pressure.
When diverticulitis strikes, treatment intensity depends on severity.
When diverticulitis strikes, treatment intensity depends on severity. Mild cases can often be managed at home with a clear liquid diet for a few days, oral antibiotics, and pain relievers like acetaminophen. Your doctor might recommend avoiding anti-inflammatory drugs like ibuprofen, which could increase bleeding risk. Rest is crucial during flare-ups. Most people start feeling better within 2-3 days of treatment.
Severe diverticulitis requires hospitalization for IV antibiotics, IV fluids, and careful monitoring.
Severe diverticulitis requires hospitalization for IV antibiotics, IV fluids, and careful monitoring. If complications develop like abscesses, doctors might need to drain them using CT-guided procedures. Surgery becomes necessary in cases of:
- Perforation of the bowel - Large abscesses that don't respond to drainage -
- Perforation of the bowel - Large abscesses that don't respond to drainage - Severe bleeding that won't stop - Bowel obstruction - Recurrent episodes that significantly impact quality of life
Surgical options range from removing the affected colon segment to temporary colostomy in emergency situations.

Recent research has questioned the routine use of antibiotics for uncomplicated diverticulitis, with some studies showing similar outcomes with supportive care alone.
Recent research has questioned the routine use of antibiotics for uncomplicated diverticulitis, with some studies showing similar outcomes with supportive care alone. Scientists are also investigating probiotics, anti-inflammatory medications, and newer surgical techniques that might improve outcomes. The field is moving toward more personalized treatment approaches based on individual risk factors and symptom patterns.
Living With Diverticular Disease
Living well with diverticular disease centers on understanding your body's signals and making thoughtful lifestyle choices. Many people find that keeping a food diary helps identify personal triggers, though common culprits include very spicy foods, excessive alcohol, and sometimes nuts or seeds. During symptom-free periods, gradually building up to a high-fiber diet becomes your foundation for long-term health.
