Diverticulitis recovery

Overview

Diverticulitis is when small pouches (called diverticula) in the lining of your digestive system become inflamed or infected. These pouches usually form in the lower part of your large intestine (colon). Recovery means getting better after an episode of diverticulitis, often with rest and diet changes.

Yes, diverticulosis is common, especially after age 40. About 1 in 5 people with diverticulosis will develop diverticulitis at some point.

It mainly affects older adults, especially those over 60. However, younger people can also get it, particularly if their diet is low in fiber and high in red meat.

Symptoms

Common symptoms

• Sudden pain in the lower left side of your belly
• Fever and chills
• Nausea and vomiting
• Changes in bowel habits (diarrhea or constipation)

Symptoms in children

• Diverticulitis is rare in children, but symptoms may include abdominal pain, fever, and vomiting.

Symptoms in older adults

• Older adults may have less specific symptoms like vague abdominal discomfort, bloating, or confusion. Pain may be milder but still serious.

Causes

Main causes

• The exact cause is not fully known, but it is thought that hardened stool or bacteria get trapped in the pouches (diverticula), leading to inflammation or infection.

Risk factors

• Low-fiber diet
• High intake of red meat and processed foods
• Being overweight or obese
• Smoking
• Lack of exercise
• Use of certain medications like non-steroidal anti-inflammatory drugs (NSAIDs) or steroids

When to see a doctor

See a doctor urgently if:

• If you have severe pain or high fever, seek same-day care.
• If you are vomiting or can't drink fluids.

Book a routine appointment if:

• Make an appointment if you have mild belly pain that lasts more than a few days.
• If you have changes in bowel habits that worry you.

Diagnosis

Your doctor will ask about your symptoms and examine your belly. They may order tests to confirm diverticulitis and rule out other problems.

Tests that may be done

• Blood tests to check for signs of infection
• A CT scan of the abdomen – this is the best test to see diverticulitis
• Sometimes a stool sample to check for infection or bleeding

What to expect at your appointment

If you have mild symptoms, the doctor may recommend home care. If symptoms are more severe, you may need to go to the hospital for a short stay and IV treatments.

Treatment

Treatment for diverticulitis depends on how severe the infection is. Mild cases are often managed at home with rest, a clear liquid diet, and antibiotics if needed. Severe cases may require hospital care.

Self-care at home

• Rest – take it easy until pain improves
• Clear liquid diet for a day or two (broth, water, clear juice, gelatin)
• Slowly add soft, low-fiber foods (like rice, eggs, toast) as pain goes away
• Avoid high-fiber foods until fully recovered
• Use a warm compress on your belly for comfort

Medical treatments

Your doctor may recommend antibiotics for an infection. These are taken by mouth for mild cases or given through a vein in the hospital. Pain relievers may also be recommended, but avoid NSAIDs (like ibuprofen) as they can worsen diverticulitis. Always follow your doctor's advice.

When is surgery considered?

Surgery is rarely needed for a first episode. It may be considered if you have repeated severe attacks, a complication like a pocket of pus (abscess), or a blockage in the bowel. Surgery often involves removing the affected part of the colon.

Living with this condition

After recovery, most people can return to their normal activities. You may need to make some long-term changes to prevent future episodes, such as eating more fiber.

Lifestyle tips

• Eat a high-fiber diet with plenty of fruits, vegetables, and whole grains
• Drink plenty of water (8 glasses a day) to help fiber work
• Get regular exercise, like walking 30 minutes a day
• Maintain a healthy weight
• Avoid smoking and limit alcohol

Diet and exercise

A high-fiber diet can help prevent future attacks. Increase fiber slowly to avoid gas and bloating. Aim for 25–30 grams per day. Regular exercise helps keep your digestive system healthy and reduces inflammation.

Mental health and emotional wellbeing

Dealing with diverticulitis can be stressful and worrying. It's normal to feel anxious about pain or future attacks. If you feel overwhelmed, talk to your doctor or a counselor. You are not alone, and support is available.

Prevention

While you cannot prevent diverticulosis (the pouches), you may reduce your risk of diverticulitis by eating a high-fiber diet, staying active, drinking plenty of water, and avoiding constipation.

Screening programmes

There are no routine screening tests for diverticulitis. However, after recovery, your doctor may recommend a colonoscopy to check the health of your colon and rule out other conditions.

Complications

If left untreated

• Abscess – a pocket of pus in the abdomen that may need draining
• Peritonitis – infection of the lining of your belly, which is a medical emergency
• Obstruction – a blockage in the bowel that prevents food from passing
• Fistula – an abnormal connection between the bowel and another organ (like the bladder)

Long-term outlook

Most people with diverticulitis recover fully with proper treatment. With healthy lifestyle changes, many have no further problems. Even if you have a severe episode, modern treatments are very effective. Stay in touch with your doctor and follow their advice for the best chance of a healthy recovery.
