An Introduction To Diverticular Disease

Updated: Jun 15

Diverticular Disease is a common digestive disorder that occurs when small pouches known as diverticula develop in the lining of the colon or large intestine. This disease can be painful and uncomfortable, but there are ways to manage it. In this article, we will discuss everything from the basics of Diverticular Disease to the types, causes, symptoms, diagnosis, and treatment options available. A diverticulum, which is a mucosal protrusion through the intestinal wall, is a characteristic feature of this condition. It occurs along natural areas of weakness in the large intestine, where there is only one complete muscular layer, the inner circular layer, whereas the small intestine and rectum have two muscular layers. We will also provide answers to some frequently asked questions about this disease and how you can find support and resources to help you live with it.

What is Diverticular Disease?

Diverticular disease is a condition that affects the colon. It is characterized by the formation of small pouches called diverticula. This can cause inflammation and abdominal pain. Diagnosing diverticular disease usually involves procedures like a colonoscopy or CT scan. Management often involves lifestyle changes and medication.

Understanding the Basics

Diverticular disease involves the formation of small pouches, known as diverticula or sacs, in the colon wall. Diverticulosis refers to the presence of diverticula without inflammation, while diverticulitis is the inflammation of diverticula that can cause symptoms like abdominal pain and fever. Other possible complications include diverticular bleeding and fistulas. Fortunately, this condition can be managed by following a high-fiber diet and ensuring adequate hydration. By prioritizing nutrition and taking care of the bowel wall, individuals can minimize the risk of acute diverticulitis and other complications.

Types of Diverticular Disease

Diverticular disease can be classified into two main types: uncomplicated and complicated. Uncomplicated diverticulitis refers to mild inflammation without any complications. On the other hand, complicated diverticulitis includes more serious issues such as abscesses, perforations, or obstructions. Diverticular bleeding can occur when blood vessels near the diverticula rupture, while peritonitis is an infection of the abdominal cavity that can result from diverticular disease. Understanding the different types of diverticular disease is essential for proper diagnosis and management of this condition.

Symptoms of Diverticular Disease

Symptoms of diverticular disease can vary but commonly include abdominal pain, bloating, and constipation. In cases of diverticulitis, additional symptoms like fever and changes in bowel habits may occur. Diverticular bleeding can lead to blood in the stool or rectal bleeding. If you notice blood coming from your rectum, it is important to seek medical attention promptly. Complications of diverticular disease can cause severe abdominal pain and tenderness. If you experience any of these symptoms, it is important to seek medical attention promptly.

Causes of Diverticular Disease

The development of diverticular disease is thought to be related to a low-fiber diet, which can lead to constipation and increased pressure in the colon. Other contributing factors include obesity, lack of physical activity, and aging, as the prevalence increases with age. Smoking and certain medications may also play a role in its development. While the exact cause of diverticular disease remains unclear, these factors are believed to contribute to its occurrence.

Who is at Risk of Developing Diverticular Disease?

Certain factors increase the risk of developing diverticular disease. Age plays a role, with older adults, especially those over 50, being more susceptible. A low-fiber diet, obesity, and lack of physical activity also contribute. Additionally, certain medications and family history may increase the risk.


Diagnosis involves a thorough physical examination and evaluation of medical history. To confirm the diagnosis, healthcare professionals may order diagnostic tests such as a colonoscopy or CT scan. Blood tests can help assess inflammation levels and rule out other possible conditions. Stool tests may be conducted to check for signs of infection or bleeding. Additionally, a barium enema (also called a lower GI series) may be performed. This test injects liquid barium into your rectum and colon, making your colon more visible on X-rays. It can show if any are inflamed or infected, providing valuable information for diagnosing diverticular disease.

Treatment Options

Treatment options vary based on the severity and complications. For mild cases of diverticulosis, lifestyle changes can be beneficial. Uncomplicated diverticulitis may be managed with a liquid diet, antibiotics, and pain medication. However, complicated diverticulitis may require hospitalization and possibly surgical intervention. It's essential to tailor treatment plans for diverticular disease to meet the individual's specific needs. By doing so, healthcare providers can ensure the most effective course of action to address this condition.


Medications play an important role in managing diverticular disease. Antibiotics are commonly prescribed to treat diverticulitis and prevent infection. Nonsteroidal anti-inflammatory drugs (NSAIDs) can help alleviate discomfort. Laxatives may be used to relieve constipation by promoting bowel movements. Probiotics are often recommended to restore a healthy balance of gut bacteria. It is important to discuss individualized medication regimens with a healthcare professional to ensure proper management. By following a tailored approach, medications can effectively support the treatment of this condition.

Lifestyle Changes For Managing Diverticular Disease

Adopting a high-fiber diet can help prevent and manage diverticular disease. Drinking enough water is important for maintaining proper bowel function and hydration. Regular exercise and physical activity promote healthy digestion and reduce the risk of complications. Avoiding trigger foods like popcorn or nuts can be beneficial. Managing stress levels through relaxation techniques or therapy supports overall well-being. By incorporating these lifestyle changes, individuals can effectively manage diverticular disease and improve their quality of life.

Can Diverticular Disease Be Prevented?

Preventing diverticular disease is possible through healthy lifestyle choices. A high-fiber diet can reduce the risk of diverticula formation, while regular exercise promotes bowel regularity. Staying hydrated and avoiding certain foods like popcorn and nuts may also lower the risk of developing diverticulitis.

Living With Diverticular Disease

Effective management of diverticular disease involves making lifestyle modifications to alleviate symptoms. Regular monitoring and follow-up appointments are essential for proper management. Understanding potential triggers for flare-ups can help individuals better manage their symptoms. It's important to take prescribed medications, including antibiotics, as directed by a healthcare professional. Making dietary changes, such as adding more fiber and avoiding trigger foods, can also help alleviate symptoms. By adopting these strategies, individuals can live a healthier life with diverticular disease.

Coping With Symptoms

Managing abdominal pain and discomfort can provide relief from diverticular disease symptoms. Pain relievers can help alleviate the pain, while following a liquid diet during acute attacks of diverticulitis allows the colon to rest and heal. Incorporating stress-reducing techniques like meditation or yoga may also help alleviate symptoms. Practicing good hygiene and proper toilet habits can help prevent infections and complications. Seek medical attention if you experience severe or persistent symptoms to ensure proper treatment.

Exercise And Physical Activity

Engaging in regular physical activity promotes healthy bowel movements and reduces the risk of complications. Low-impact exercises like walking or swimming benefit individuals with this condition. Consulting a healthcare professional before starting any new exercise regimen is important. Maintaining a healthy weight through exercise helps manage diverticular disease symptoms. Gentle stretching exercises relieve muscle tension and improve flexibility. Remember to consult a healthcare professional before beginning any exercise routine, especially if you have diverticular disease.

Diet And Nutrition

Eating a diet high in fiber can prevent the formation of diverticula and maintain regular bowel movements. Include foods such as fruits, vegetables, whole grains, and legumes that are rich in fiber. Staying hydrated by drinking enough water is essential for proper digestion. Manage diverticular disease symptoms by avoiding trigger foods like spicy or greasy foods. For personalized dietary recommendations, consult a registered dietitian. If you currently don't have a diet high in fiber, you should add fiber gradually. This helps avoid bloating and abdominal discomfort. The target is to eat 25 to 30 grams of fiber daily. Drink at least 8 cups of fluid daily. Fluid will help soften your stool. Exercise also promotes bowel movement and helps prevent constipation.
