What is Diverticular Disease and How Can it be Treated?

Diverticular disease is a common condition that affects the colon, particularly the lower part known as the sigmoid colon. It involves the formation of small pouches, called diverticula, in the wall of the colon. While diverticular disease is usually benign and doesn’t cause any symptoms, it can occasionally lead to complications and require medical intervention. In this article, we will explore the various aspects of diverticular disease, including its causes, diagnosis, symptoms, treatment options, and preventive measures.

What is Diverticular Disease?

Diverticular disease refers to the presence of diverticula, which are small, bulging pouches that form in the lining of the colon. These pouches typically develop in weakened areas of the colon wall, usually where blood vessels pass through the muscular layer. Diverticular disease encompasses two main conditions: diverticulosis and diverticulitis.

Diverticulosis is the term used to describe the presence of diverticula without inflammation or infection. It is a common age-related condition, with the prevalence increasing with age. In fact, around half of individuals over the age of 60 have diverticulosis.

Diverticulitis occurs when the diverticula become inflamed or infected. This happens when faecal matter gets trapped in the diverticula, leading to bacterial overgrowth and subsequent inflammation. Diverticulitis can cause a range of symptoms and may require medical treatment.

What Causes Diverticular Disease?

The exact cause of diverticular disease is not fully understood. However, it is believed to be primarily related to a combination of factors, including a low-fibre diet, increased pressure in the colon, and age-related changes in the structure of the colon wall.

A low-fibre diet is thought to play a significant role in the development of diverticular disease. When the diet lacks sufficient fibre, the stool becomes harder and requires increased pressure to move through the colon. This increased pressure can lead to the formation of diverticula.

Other contributing factors may include obesity, sedentary lifestyle, smoking, certain medications (such as nonsteroidal anti-inflammatory drugs), and genetic predisposition. However, more research is needed to fully understand the interplay between these factors and diverticular disease.

How Can Diverticular Disease be Diagnosed?

Diagnosing diverticular disease usually involves a combination of medical history evaluation, physical examination, and diagnostic tests. If a patient presents with symptoms such as abdominal pain, changes in bowel habits, or rectal bleeding, a healthcare professional may suspect diverticular disease and initiate the diagnostic process.

One common way to diagnose diverticular disease is through a colonoscopy, which allows direct visualization of the colon and the detection of diverticula, inflammation, or other abnormalities.

Who is Most Susceptible to Diverticular Disease?

While diverticular disease can affect people of all ages, it is more common in older adult with the majority of those above 70 years of age experiencing some form of the disease. Moreover, the prevalence of diverticulitis is higher in individuals over the age of 40.

Certain factors may increase an individual’s susceptibility to diverticular disease. These include a low-fibre diet, a sedentary lifestyle, obesity, smoking, and a family history of the condition. Therefore, adopting a healthy lifestyle and dietary habits can play a crucial role in prevention.

What are the Symptoms of Diverticular Disease?

Diverticulosis, the uncomplicated form of diverticular disease, usually does not cause symptoms. Most individuals are unaware they have diverticula unless they are incidentally discovered during any tests for unrelated conditions. However, some people may experience mild symptoms such as bloating or cramping.

Diverticulitis, on the other hand, can cause more noticeable symptoms. These may include:

  1. Abdominal pain, usually in the lower left side.
  2. Fever and chills.
  3. Nausea and vomiting.
  4. Changes in bowel habits, such as constipation or diarrhoea.
  5. Rectal bleeding (less common).

If you experience severe or persistent symptoms, it is important to seek medical attention promptly as complications of diverticulitis, such as abscesses, perforation, or fistulas, may occur.

How Can Diverticular Disease be Treated?

The treatment approach for diverticular disease depends on the severity of the condition and the presence of complications. For individuals with diverticulosis and no symptoms, treatment may not be necessary. However, adopting a high-fibre diet and maintaining a healthy lifestyle can help prevent symptoms from developing and reduce the risk of complications.

In cases of uncomplicated diverticulitis, treatment typically involves a combination of rest, dietary modifications, and medication. The aim is to relieve symptoms and prevent complications. Antibiotics may be prescribed if there are signs of infection. Pain medications and a clear liquid diet are often recommended initially, followed by a gradual transition to a high-fibre diet as symptoms improve.

Complicated diverticulitis, characterized by severe symptoms or the presence of complications, may require hospitalization and more aggressive management. In some cases, surgery may be necessary to remove the affected part of the colon or to address complications such as abscesses or fistulas.

In some cases, diverticular disease can present with signs of sepsis. If that is the case emergency medical assistance must be sought to deal with the issue straight away.

How Can You Help Prevent Diverticular Disease?

While it may not be possible to completely prevent diverticular disease, certain lifestyle modifications can help reduce the risk and promote colon health:

  1. Eat a high-fibre diet: Include plenty of fruits, vegetables, whole grains, legumes, and nuts in your diet. Adequate fibre intake helps promote regular bowel movements and prevents constipation.
  2. Stay hydrated: Drink enough water to maintain proper hydration, as it contributes to softer stools and smooth bowel movements.
  3. Exercise regularly: Engage in regular physical activity to promote bowel motility and maintain a healthy weight.
  4. Quit smoking: Smoking has been linked to an increased risk of diverticular disease, among other health issues. Seek support to quit smoking if necessary.
  5. Manage stress: Chronic stress can affect bowel function and contribute to digestive issues. Find healthy coping mechanisms to manage stress levels.

Diverticular disease is a common condition characterised by the presence of diverticula in the colon. While diverticulosis is usually asymptomatic, diverticulitis can cause discomfort and lead to complications in some cases. By understanding the causes, symptoms, and available treatment options, individuals can take proactive steps to manage diverticular disease effectively. Adopting a high-fibre diet, maintaining a healthy lifestyle, and seeking medical advice promptly can contribute to better colon health and a reduced risk of complications associated with diverticular disease.
