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 Diverticulitis.
Diverticulitis develops through a two-step process that begins with the formation of diverticula.
Diverticulitis develops through a two-step process that begins with the formation of diverticula. These small pouches form when increased pressure inside your colon pushes against weak spots in the intestinal wall, much like how a tire might bulge where the rubber is thin. This pressure often results from straining during bowel movements, particularly when stool is hard and difficult to pass.
Once diverticula exist, inflammation can occur when material gets trapped inside these pouches.
Once diverticula exist, inflammation can occur when material gets trapped inside these pouches. Bacteria, small food particles, or waste can become lodged in a diverticulum, creating an environment where harmful bacteria multiply. This bacterial overgrowth triggers an inflammatory response as your immune system attempts to fight the infection, leading to swelling, pain, and other symptoms of diverticulitis.
Several factors contribute to the increased pressure that creates diverticula in the first place.
Several factors contribute to the increased pressure that creates diverticula in the first place. A diet low in fiber is the primary culprit, as it leads to smaller, harder stools that require more muscular effort to move through the colon. Age-related changes in the colon wall, including decreased elasticity and muscle tone, also make diverticula formation more likely. Chronic constipation, certain medications, and lifestyle factors can further increase the internal pressure that leads to these problematic pouches.
Risk Factors
- Age over 40 years
- Low-fiber diet with processed foods
- Chronic constipation and straining
- Obesity or being significantly overweight
- Smoking cigarettes
- Lack of regular physical exercise
- Regular use of NSAIDs or steroids
- Family history of diverticular disease
- Previous episodes of diverticulitis
Diagnosis
How healthcare professionals diagnose Diverticulitis:
- 1
When you visit your doctor with suspected diverticulitis, they'll start with a detailed discussion of your symptoms and a physical examination.
When you visit your doctor with suspected diverticulitis, they'll start with a detailed discussion of your symptoms and a physical examination. Your doctor will press gently on different areas of your abdomen to locate tender spots and check for signs of complications. They'll also listen to your bowel sounds with a stethoscope and may perform a rectal exam to rule out other conditions.

Blood tests are typically ordered to look for signs of infection, such as elevated white blood cell count, and to check for anemia if bleeding is suspected.
Blood tests are typically ordered to look for signs of infection, such as elevated white blood cell count, and to check for anemia if bleeding is suspected. A CT scan of your abdomen and pelvis is the most common and reliable test for diagnosing diverticulitis. This imaging study can show inflamed diverticula, complications like abscesses, and help rule out other conditions that cause similar symptoms.

Your doctor will also consider other conditions that can mimic diverticulitis, including appendicitis, inflammatory bowel disease, irritable bowel syndrome, ovarian cysts in women, and colon cancer.
Your doctor will also consider other conditions that can mimic diverticulitis, including appendicitis, inflammatory bowel disease, irritable bowel syndrome, ovarian cysts in women, and colon cancer. During acute episodes, colonoscopy is usually avoided because it can increase the risk of perforation, but your doctor may recommend this procedure several weeks after symptoms resolve to examine your colon more thoroughly and rule out other problems.
Complications
- Most people with diverticulitis recover completely without lasting problems, but complications can occur in about 10 to 15 percent of cases.
- The most serious complication is perforation, where the inflamed diverticulum ruptures, potentially spilling intestinal contents into the abdominal cavity.
- This can lead to peritonitis, a life-threatening infection that requires emergency surgery.
- Other complications include abscess formation, where pockets of pus develop near the inflamed area, and intestinal obstruction if scar tissue blocks the colon.
- Fistulas, abnormal connections between the colon and other organs like the bladder, can develop in rare cases.
- Severe bleeding, while uncommon in diverticulitis, can occasionally occur and may require hospitalization or procedures to stop it.
- Most complications develop during the first episode or in people with severe, untreated cases, which is why prompt medical attention is so important.
Prevention
- The most effective way to prevent diverticulitis is maintaining a high-fiber diet throughout your life.
- Aim for 25 to 35 grams of fiber daily from sources like vegetables, fruits, whole grains, and legumes.
- Fiber helps create softer, bulkier stools that move through your colon more easily, reducing the pressure that creates diverticula.
- Gradually increase fiber intake over several weeks to avoid bloating and gas.
- Staying well-hydrated is equally important, as water helps fiber do its job effectively.
- Regular exercise also promotes healthy digestion and normal bowel movements, reducing your risk of constipation and the straining that contributes to diverticula formation.
- Even moderate activities like walking for 30 minutes most days can make a significant difference.
- While you can't change risk factors like age and genetics, avoiding smoking and maintaining a healthy weight can reduce your overall risk.
- If you've already had an episode of diverticulitis, following these preventive measures becomes even more crucial for avoiding future flare-ups.
Treatment for diverticulitis depends on the severity of your symptoms and whether complications are present.
Treatment for diverticulitis depends on the severity of your symptoms and whether complications are present. For mild cases, your doctor may recommend a clear liquid diet for a few days to give your colon time to heal, followed by a gradual return to solid foods. Antibiotics are commonly prescribed to fight bacterial infection, though recent studies suggest they may not always be necessary for uncomplicated cases.
Pain management typically involves over-the-counter medications, though your doctor may recommend avoiding NSAIDs as they can increase bleeding risk.
Pain management typically involves over-the-counter medications, though your doctor may recommend avoiding NSAIDs as they can increase bleeding risk. Rest is important during acute episodes, and many people feel better within a few days of starting treatment. For recurrent episodes, some doctors may suggest probiotics to help restore healthy gut bacteria, though the evidence for their effectiveness remains mixed.
Severe cases may require hospitalization for IV antibiotics, pain control, and close monitoring.
Severe cases may require hospitalization for IV antibiotics, pain control, and close monitoring. If complications develop, such as abscesses, your doctor might need to drain them using a needle guided by CT scan. Surgery becomes necessary in cases of perforation, obstruction, or recurrent severe episodes that don't respond to medical treatment.
Recent research has shifted away from recommending surgery after just two episodes, as many people do well with continued medical management.
Recent research has shifted away from recommending surgery after just two episodes, as many people do well with continued medical management. However, younger patients or those with complicated diverticulitis may still be candidates for surgical removal of the affected portion of colon. Recovery from surgery typically takes several weeks, and most people experience significant improvement in their quality of life afterward.
Living With Diverticulitis
Living well with diverticulitis means developing habits that support your digestive health while staying alert to early warning signs. Many people find that keeping a food diary helps them identify triggers that might worsen symptoms. While the old advice to avoid nuts and seeds has been debunked, some people still find that certain foods don't agree with them during recovery periods.
