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 Acute Diverticulitis.
Acute diverticulitis develops when diverticula, small pouches in the colon wall, become inflamed or infected.
Acute diverticulitis develops when diverticula, small pouches in the colon wall, become inflamed or infected. These pouches form over time when increased pressure inside the colon pushes against weak spots in the intestinal wall. Think of it like a tire developing weak spots that eventually bulge outward under pressure.
The inflammation typically starts when material gets trapped inside these pouches.
The inflammation typically starts when material gets trapped inside these pouches. This could be partially digested food, bacteria, or waste products that normally would pass through the colon. Once trapped, bacteria multiply and cause infection, leading to swelling, pain, and other symptoms. The body's immune response kicks in, sending white blood cells to fight the infection, which creates more inflammation.
Several factors can trigger an acute episode.
Several factors can trigger an acute episode. A low-fiber diet plays a major role because it leads to smaller, harder stools that require more pressure to move through the colon. This increased pressure can force material into the diverticula and worsen existing pouches. Certain medications, particularly anti-inflammatory drugs and opioids, may increase risk by affecting gut bacteria or reducing protective mechanisms in the intestinal lining.
Risk Factors
- Age over 40 years
- Low-fiber, high-fat Western diet
- Lack of regular physical exercise
- Obesity or excess abdominal weight
- Smoking cigarettes
- Regular use of anti-inflammatory medications
- Family history of diverticular disease
- Previous episode of diverticulitis
- Certain medications including opioids and steroids
- Chronic constipation
Diagnosis
How healthcare professionals diagnose Acute Diverticulitis:
- 1
When you visit your doctor with suspected diverticulitis, they'll start with a detailed discussion of your symptoms and medical history.
When you visit your doctor with suspected diverticulitis, they'll start with a detailed discussion of your symptoms and medical history. The classic presentation includes left-sided abdominal pain, fever, and changes in bowel habits. Your doctor will perform a physical examination, gently pressing on your abdomen to check for tenderness, swelling, or masses. They'll also check your vital signs, as fever and elevated heart rate are common.

Blood tests typically come next to look for signs of infection and inflammation.
Blood tests typically come next to look for signs of infection and inflammation. A complete blood count can reveal elevated white blood cells, while other markers like C-reactive protein may be elevated. Your doctor might also order urine tests to rule out urinary tract infections, which can cause similar symptoms. A CT scan of your abdomen and pelvis is often the most helpful imaging test, as it can show inflamed diverticula, complications like abscesses, and rule out other conditions.

Doctors must distinguish diverticulitis from several other conditions that cause similar symptoms.
Doctors must distinguish diverticulitis from several other conditions that cause similar symptoms. These include appendicitis (especially if you have right-sided pain), inflammatory bowel disease, irritable bowel syndrome, urinary tract infections, and even ovarian cysts in women. Colonoscopy is usually avoided during acute episodes because it can worsen inflammation, but may be recommended later to evaluate the extent of diverticular disease.
Complications
- Most people with acute diverticulitis recover without serious problems, but complications can occur in about 10-25% of cases.
- The most common complication is abscess formation, where pockets of infected fluid develop near the inflamed diverticula.
- Small abscesses often respond to antibiotics alone, while larger ones may require drainage procedures.
- Perforation, where the colon wall develops a hole, is more serious and can lead to peritonitis, a dangerous infection of the abdominal cavity.
- Other complications include bowel obstruction, where inflammation and scarring block the normal passage of stool, and fistula formation, where abnormal connections develop between the colon and other organs like the bladder or vagina.
- Severe bleeding, while less common in acute diverticulitis, can occasionally occur and may require emergency treatment.
- People who experience complications or have recurrent episodes may need surgical treatment to remove the affected portion of colon, though this is less common than in the past as treatment approaches have improved.
Prevention
- Preventing diverticulitis focuses largely on dietary and lifestyle changes that keep your digestive system healthy.
- A high-fiber diet stands as the most effective prevention strategy.
- Aim for 25-35 grams of fiber daily from sources like fruits, vegetables, whole grains, and legumes.
- Fiber keeps stools soft and bulky, reducing pressure in the colon and helping prevent new diverticula from forming.
- Add fiber gradually to your diet to avoid gas and bloating.
- Regular physical activity also plays a crucial role in prevention.
- Exercise helps maintain normal bowel function and may reduce inflammation throughout the body.
- Even moderate activity like walking 30 minutes most days can make a significant difference.
- Staying well-hydrated supports the fiber in your diet and keeps stools moving smoothly through your colon.
- While you can't change risk factors like age and genetics, you can modify several lifestyle factors.
- Quitting smoking reduces your risk significantly, as smoking appears to alter gut bacteria and increase inflammation.
- Maintaining a healthy weight reduces pressure on your abdomen and colon.
- If you need pain medications regularly, discuss alternatives with your doctor, as some medications may increase diverticulitis risk when used long-term.
Treatment for acute diverticulitis depends on the severity of your symptoms and whether complications have developed.
Treatment for acute diverticulitis depends on the severity of your symptoms and whether complications have developed. For mild cases, your doctor may recommend outpatient treatment with oral antibiotics, typically lasting 7-10 days. Common antibiotics include ciprofloxacin combined with metronidazole, or amoxicillin-clavulanate. You'll also need to modify your diet temporarily, starting with clear liquids and gradually advancing to low-fiber foods as symptoms improve.
More severe cases require hospitalization for intravenous antibiotics, pain management, and close monitoring.
More severe cases require hospitalization for intravenous antibiotics, pain management, and close monitoring. You'll likely receive IV fluids and be kept on bowel rest, meaning no food by mouth initially. This gives your colon time to heal without the stress of digesting food. Pain medications help manage discomfort, though doctors avoid certain types that might mask important symptoms or worsen the condition.
If complications develop, such as abscesses, perforation, or bowel obstruction, more aggressive treatment becomes necessary.
If complications develop, such as abscesses, perforation, or bowel obstruction, more aggressive treatment becomes necessary. Small abscesses might be drained using a needle guided by CT scan, while larger ones may require surgical drainage. Emergency surgery is sometimes needed for serious complications like perforation or severe bleeding. The type of surgery depends on your specific situation but might involve removing the affected portion of colon.
Recent research has shown promising results with newer approaches.
Recent research has shown promising results with newer approaches. Some studies suggest that uncomplicated diverticulitis might be treated without antibiotics in certain patients, though this approach is still being studied. Probiotics are being investigated for their potential to restore healthy gut bacteria, though evidence remains mixed. Ongoing research into anti-inflammatory treatments and personalized therapy based on genetic factors offers hope for more targeted treatments in the future.
Living With Acute Diverticulitis
Living successfully with diverticular disease after an acute episode requires ongoing attention to diet and lifestyle, but most people adapt well and live normal, active lives. Your doctor will likely recommend gradually increasing fiber in your diet once the acute episode resolves. Start slowly and pay attention to how different foods affect you. Some people find that certain foods like nuts, seeds, or popcorn cause problems, while others can eat these without issue.
