Sigmoid Diverticulitis - Symptoms, Reasons And Treatment

Sigmoid diverticulitis occurs when small pouches called diverticula become inflamed or infected in the sigmoid colon, which is the lower part of the large intestine. These diverticula can develop due to weak spots in the colon wall, leading to the formation of bulging pouches. The inflammation or infection of these pouches is known as diverticulitis. Several factors can contribute to the development of sigmoid diverticulitis, including a low-fiber diet, which can lead to constipation and increased pressure within the colon. This increased pressure can cause the colon wall to weaken and form diverticula over time. Other factors that may play a role include age, genetics, obesity, and a sedentary lifestyle.

What Are the Symptoms of Sigmoid Diverticulitis

Sigmoid diverticulitis may cause symptoms such as lower abdominal pain, often on the left side, which can range from mild to severe and become worse over time. Patients may also experience changes in bowel habits, such as constipation or diarrhea, bloating, gas, and sometimes fever. In more severe cases, individuals may develop nausea, vomiting, and abdominal tenderness. It's important to seek medical attention if you experience these symptoms to receive proper diagnosis and treatment.

Causes of Sigmoid Diverticulitis

The main causes include the formation of small pouches called diverticula in the colon wall, which can become infected or inflamed.  This inflammation often results from fecal matter becoming trapped in the diverticula, leading to bacterial overgrowth and subsequent infection.  Other contributing factors may include a low-fiber diet, obesity, aging, and genetic predisposition.  Lifestyle choices such as poor bowel habits and lack of physical activity can also play a role in increasing the risk of developing sigmoid diverticulitis.

Types Of Sigmoid Diverticulitis

Sigmoid diverticulitis can be classified into different types based on the severity of the condition. These types include uncomplicated diverticulitis, which involves inflammation without complications; complicated diverticulitis, where complications like abscesses, perforations, or fistulas occur; recurrent diverticulitis, which refers to repeated episodes of inflammation; and chronic diverticulitis, characterised by persistent or long-lasting symptoms. Each type may require different management approaches, ranging from conservative treatments such as antibiotics and dietary changes to more invasive interventions like surgery in severe cases.

Risk Factors

Sigmoid diverticulitis, an inflammatory condition of the sigmoid colon, is associated with several risk factors. These include older age, a diet low in fibre and high in red meat, obesity, smoking, and a sedentary lifestyle. Genetic predisposition may also play a role in developing diverticulitis. Additionally, certain medications like nonsteroidal anti-inflammatory drugs (NSAIDs) can increase the risk. Proper management involves lifestyle modifications such as a high-fibre diet, regular exercise, and smoking cessation to reduce the risk of developing sigmoid diverticulitis and its complications.

Diagnosis of Sigmoid Diverticulitis

Imaging studies like a CT scan or ultrasound may be ordered to visualize the inflamed diverticula and any complications like abscesses or perforations.  Blood tests can help evaluate inflammation levels and rule out other conditions.  In some cases, a colonoscopy may be recommended to confirm the diagnosis and exclude other gastrointestinal disorders.  A comprehensive diagnostic approach involving a combination of these methods is crucial for accurate identification and management of sigmoid diverticulitis.

Treatment for Sigmoid Diverticulitis

Treatment options for sigmoid diverticulitis depend on the severity of the condition. In mild cases, the primary approach may involve antibiotics, a clear liquid diet, and rest to allow the colon to heal. For more severe cases or recurrent episodes, hospitalization may be required for intravenous antibiotics and bowel rest. 

In some instances, surgery may be necessary to remove the affected portion of the colon. Lifestyle modifications such as increasing fiber intake, staying hydrated, and regular exercise can also help manage diverticulitis and prevent future flare-ups. It is crucial for individuals with sigmoid diverticulitis to work closely with their healthcare provider to determine the most appropriate treatment plan.
