Diverticulitis

What is Diverticulitis?

Diverticulitis is inflammation or infection of small bulging pouches called 'diverticula' that can form in the wall of the colon or large intestine. The presence of these pouches without inflammation is called diverticulosis and, in many cases, is asymptomatic. When one or more diverticula become inflamed or infected, the condition becomes diverticulitis.

Diverticulitis is an acute gastrointestinal condition in most people, but some patients have recurrent episodes that require long-term management.

What are the Types of Diverticulitis?

Doctors commonly classify diverticulitis according to its severity and associated complications. The various types of diverticulitis are as follows:

Stages of Diverticulitis

The severity of diverticulitis is commonly classified using the Hinchey classification, which helps determine the extent of inflammation and guide treatment decisions. Take a look at the various stages of diverticulitis based on severity:

How Common is Diverticulitis in India?

Reliable nationwide estimates of the prevalence of diverticulitis in India are lacking. Gastroenterologists, however, are seeing more patients with diverticulitis because of changes in diet, longer life expectancy and better diagnostic imaging.

Globally, diverticular disease has a high prevalence in adults above 60 years, and its prevalence rises sharply with age. Indian hospital-based studies suggest that left-sided diverticular disease, once thought to be uncommon, is now being seen more often in urban populations.

Experts believe that with obesity, constipation, diabetes and other lifestyle-related disorders, the burden of diverticular disease may continue to rise.

What are the Symptoms of Diverticulitis?

The signs and symptoms of diverticulitis vary from minor pain in the abdomen to severe pain due to infections that need immediate medical treatment. Common early signs and advanced stage symptoms of diverticulitis include:

Diseases Similar to Diverticulitis

Sometimes it can be hard to distinguish diverticulitis from other gastrointestinal diseases because of similar symptoms. Understanding the differences can help people seek early and effective treatment.

Below is a general outline of diseases that have similar symptoms to diverticulitis, making it easier to diagnose them.

What are the Causes and Risk Factors of Diverticulitis?

Diverticulitis develops when diverticula become inflamed or infected, although the exact mechanism remains under investigation.

Common causes and risk factors of diverticulitis include:

• Diverticulosis: People with diverticulosis already have diverticula. These provide the structural basis for diverticulitis.

• Low-Fibre Diet: Low-fibre diets may lead to increased pressure within the colon and contribute to diverticular disease.

• Ageing: The risk increases with age as the bowel wall gradually weakens.

• Obesity: People with excess body weight are more likely to have this disease.

• Chronic Constipation: Straining during bowel movements can cause increased pressure within the colon.

• Physical Inactivity: A sedentary lifestyle has been linked to an increased risk of diverticular disease.

• Smoking: Tobacco use can increase inflammation and worsen disease outcomes.

• Some Medications: Long-term use of some anti-inflammatory drugs, steroids or immunosuppressive drugs may increase your susceptibility.

• Genetic Factors: An individual's risk can be influenced by family history.

• Altered Gut Microbiome: Alterations in intestinal bacteria may contribute to inflammation in susceptible individuals.

What are the Complications of Diverticulitis?

Although many cases respond well to treatment, delayed disease management may result in serious complications. Potential complications of diverticulitis include the following:

• Abscess Formation: Pus may accumulate around the infected diverticulum. Drainage may be necessary.

• Bowel Perforation: A tear in the intestinal wall may allow intestinal contents to escape into the abdominal cavity.

• Peritonitis: Widespread infection of the membrane lining the abdomen. It is a medical emergency.

• Fistula Formation: Abnormal connections can form between the colon and adjacent organs, like the bladder.

• Intestinal Obstruction: Inflammation and scarring can partially or totally block the intestines.

• Recurrent Diverticulitis: Having multiple episodes makes it more likely that surgery will be needed.

• Sepsis: Severe infection can spread through the bloodstream and affect many organs.

• Reduced Quality of Life: Repeated attacks and chronic abdominal symptoms may interfere with daily activities.

When Should I See My Healthcare Provider?

You should seek medical attention promptly if you experience symptoms that may indicate diverticulitis or its complications.

Consult a healthcare provider if you notice any of the following:

• Persistent Pain in Lower Abdomen: Pain, especially in the lower left side of the abdomen, that lasts for several hours or gets worse.

• Fever with Abdominal Pain: Fever and stomach pain may signal an infection that needs treatment.

• Severe Nausea or Vomiting: If vomiting occurs repeatedly, it can lead to dehydration and can be a sign of a bowel obstruction.

• Blood in the Stool: Any rectal bleeding should be evaluated by a physician to rule out diverticulitis, colorectal cancer or gastrointestinal bleeding.

• Difficulty Passing Stool or Gas: Ongoing constipation or inability to pass gas may be a sign of intestinal obstruction.

• Bloating: Gradual bloating or abdominal distension warrants urgent assessment.

• Recurring Symptoms After Diverticulitis: Symptoms after a previous episode, such as recurrent abdominal pain or fever after a previous diverticulitis, should not be ignored.

• Sudden Worsening of Symptoms: Get emergency medical help if you have severe pain, confusion, low blood pressure or signs of sepsis.

How is Diverticulitis Diagnosed?

Doctors diagnose diverticulitis using clinical evaluation, laboratory tests and imaging studies. The main objective is to confirm inflammation and identify complications such as abscesses or perforation. The following assessments may be used to diagnose diverticulitis:

Diagnostic Overview

Unlike diabetes or hypertension, diverticulitis does not have a laboratory value that confirms the diagnosis. Imaging findings together with clinical symptoms establish the diagnosis.

How is Diverticulitis Managed or Treated?

Treatment of diverticulitis depends on disease severity, the presence of complications and the patient's overall health. The various treatment methods for diverticulitis include:

Common Medicines Used to Treat Diverticulitis

Medications administered for diverticulitis are based on the level of infection and the presence of complications. The following are some commonly administered medications for diverticulitis:

• Amoxicillin-clavulanate, Metronidazole and Ciprofloxacin: Amoxicillin-clavulanate is frequently used as a monotherapy antibiotic in selected cases. Metronidazole can also be combined with ciprofloxacin for broader bacterial coverage. The choice depends on the severity of the disease, local patterns of antibiotic resistance and patient-related factors.

• Paracetamol: It is commonly recommended for alleviating abdominal pain and fever during an acute attack of the condition.

• Ondansetron: For controlling vomiting and nausea in cases of acute diverticulitis.

Note: Mild cases of uncomplicated diverticulitis might not need to take any antibiotics. Treatment will depend on the level of the disease as well as the health of the patient. Medications should always be taken under medical guidance only.

Living with Diverticulitis: Challenges and Caregiving

Living with diverticulitis on a daily basis is difficult, especially for people who have repeated attacks or complications. Some adjustments in lifestyle, medical consultations and assistance from family can help prevent flare-ups.

What is the Prognosis for Diverticulitis?

The prognosis is generally favourable when diverticulitis is diagnosed early and managed appropriately. Most people with uncomplicated diverticulitis recover completely within a few weeks. However, recurrent episodes can occur, particularly in individuals with persistent risk factors such as obesity or chronic constipation.

Complicated diverticulitis involving abscesses, perforation or fistulas may require surgery and a longer recovery. Regular follow-up helps reduce the risk of future complications.

Can Diverticulitis Be Prevented?

Although diverticulosis cannot always be prevented, several lifestyle measures may reduce the risk of diverticulitis and recurrent attacks.

Preventive strategies for diverticulitis include:

• Eat a Fibre-Rich Diet: Include fruits, vegetables, legumes and whole grains to promote regular bowel movements.

• Stay Active: Regular exercise helps the intestines work normally.

• Maintain a Healthy Weight: Obesity increases the risk of complications of diverticular disease.

• Drink Sufficient Fluids: Adequate hydration complements fibre intake and helps to avoid constipation.

• Do Not Smoke: Smoking may worsen inflammation and disease outcome.

• Manage Constipation Early: If you are having ongoing bowel issues, get medical advice rather than repeatedly trying to strain.

• Follow-Up on Appointments: Keep up with recommended medical reviews, which should be provided to those with previous episodes.

• Manage Chronic Health Conditions: Keep diabetes and other chronic diseases well controlled for overall recovery.

Treatment Cost of Diverticulitis

The treatment cost of diverticulitis depends on the type of treatment, severity of the disease, city, hospital and doctor’s expertise. While mild cases of diverticulitis require only medication and non-hospital treatment, more severe cases may need hospitalisation or even surgical intervention.

The approximate costs of treatment for diverticulitis are listed below:

Note: The overall cost of treatment for diverticulitis varies based on the severity of the disease, the presence of any other problems related to the illness, the city, the hospital and other factors.

Does Health Insurance Cover Diverticulitis?

Yes. In India, health insurance policies typically cover medically necessary treatment for diverticulitis, particularly when hospitalisation is required. Coverage usually include in-patient treatment, surgery where medically indicated, day care procedures and pre & post-hospitalisation expenses.

Outpatient expenses, including specialist consultation fees, diagnostic investigations like CT scans and blood tests, and medicine costs, are covered with the OPD benefit. However, the exact coverage may range from one policy to another.

If diverticulitis has been diagnosed prior to buying the policy, it will be considered a pre-existing disease (PED) and a waiting period of up to 3 years will apply. However, before purchasing a health insurance plan, please read the policy documents carefully.

How Much Health Insurance Coverage is Needed for Diverticulitis Treatment?

The amount of health insurance coverage you need for diverticulitis treatment depends on the severity of the condition, the development of complications, the type of treatment needed and the city in which you receive medical care. A cover of ₹5 lakh to ₹10 lakh may help manage expenses like hospitalisation, diagnostic imaging, specialist consultations, medicines and uncomplicated surgeries.

Some patients may require emergency surgery, intensive care, prolonged hospital stays, management of bowel perforation or sepsis or repeat surgery for recurrent disease. In such cases, a higher coverage of about ₹15 lakh to ₹20 lakh may be worth considering, especially when treatment is expected at private hospitals.

It is best to compare health insurance plans to find a policy that fits your future healthcare needs.
