About Acute Diverticulitis

Overview

Acute diverticulitis is a condition characterized by inflammation of one or more diverticula in the colon. Diverticula are small, bulging pouches that can form in the lining of the colon. When these pouches become inflamed, it can cause abdominal pain, fever, and changes in bowel habits. Acute diverticulitis can range from mild to severe, with complications such as abscess formation, bowel obstruction, or perforation. It is important to diagnose and treat acute diverticulitis promptly to prevent further complications. Diagnostic tests such as CT scans are commonly used to confirm the diagnosis and assess for any complications. Treatment typically involves a combination of antibiotics, dietary modifications (such as a clear liquid or low-fiber diet), and pain management. In some cases, hospitalization and surgical intervention may be necessary. Regular follow-up and colonoscopy may be recommended to monitor for any underlying colorectal conditions.

Causes and Risk Factors

The pathophysiological causes of acute diverticulitis are not fully understood. It is believed that bacteria in the stool can multiply and cause an infection when a diverticulum becomes blocked, possibly by a piece of stool.

Non-modifiable risk factors for acute diverticulitis cannot be changed or controlled. These include:

Age: Older adults have a higher risk than younger individuals.
Gender: Females may have a higher risk.
Genetic factors: Some studies suggest that genetics may play a role.

Modifiable risk factors for acute diverticulitis can be influenced or changed. These include:

Smoking: Smoking has been identified as an independent risk factor for the development of diverticulitis.
Obesity: Being obese increases the risk.
Lack of exercise: Not getting enough physical activity may contribute to the development of diverticulitis.
Diet: A diet high in animal fats and low in fiber is associated with an increased risk.
Medications: Certain medications, such as steroids, opiates, and non-steroidal anti-inflammatory drugs (NSAIDs), may increase the risk.

It's important to note that these risk factors are not definitive causes of acute diverticulitis but rather factors that may increase the likelihood of developing the condition. It's always best to consult with a healthcare professional for personalized advice and guidance.

Symptoms

Common early symptoms of acute diverticulitis include:

Abdominal pain, usually on the lower left side.
Abdominal bloating and cramping.

As acute diverticulitis progresses or becomes more severe, additional symptoms may occur. These can include:

Fever.
Loss of appetite.
Nausea and vomiting.

In some cases, complications can arise, leading to more severe symptoms. These may include:

Increasing pain.
Bloody stools.
Not passing gas or stool.

It's important to note that symptoms can vary from person to person, and not everyone will experience all of these symptoms. If you suspect you may have diverticulitis or if your symptoms worsen, it is recommended to seek immediate medical attention. Your doctor can determine the severity of your condition and provide appropriate treatment. Remember to always consult with your healthcare professional for personalized advice.

Diagnosis

To diagnose acute diverticulitis, doctors commonly perform the following examinations, tests, and procedures:

History and Physical examination: The doctor will conduct a physical exam and ask about symptoms and medical history to learn about any symptoms or factors contributing to your condition.
Imaging tests: The primary imaging test used to diagnose acute diverticulitis is a CT scan. This test can help visualize the inflamed diverticula in the left colon and sigmoid. A barium enema X-ray may also be used to identify diverticula.
Blood tests: A blood test may be done to check for signs of infection, such as an elevated white blood cell count.

Additional examinations, tests, and procedures may include:

Colonoscopy: A colonoscopy may be performed after symptoms resolve to rule out other conditions like inflammatory bowel disease or cancer.

Remember, these are general guidelines and individual cases may vary. It's important to consult with your healthcare professional for personalized advice and guidance.

Treatment Options

The goals of treatment for acute diverticulitis are to clear up the infection and prevent complications. Here are the different types of treatments and how they work to achieve these goals:

Medication:

Antibiotics: These medications help to fight the infection caused by diverticulitis. They target and kill the bacteria responsible for the infection, allowing the body to heal.

Therapies:

Liquid Diet: A liquid diet is often recommended initially to rest the digestive system and allow the colon to heal. This helps reduce inflammation and allows the infection to resolve.

Therapeutic Procedures:

Drainage: In cases where there is an abscess (pus-filled sac), an interventional radiologist may perform drainage of the abscess. This involves draining the abscess using imaging called fluoroscopy, which helps relieve symptoms and promote healing.
Colon resection: Rarely, in severe cases, the involved part of the intestine may need to be removed completely through surgery.

Self-care and Health Behavior Changes:

Dietary Modifications: Making changes to your diet can help prevent future episodes of diverticulitis. Increasing fiber intake, drinking plenty of fluids, and avoiding certain foods like red meat and non-aspirin non-steroidal anti-inflammatory drugs (NSAIDs) can help promote regular bowel movements and reduce pressure in the colon.

It's important to note that treatment for acute diverticulitis should be individualized based on the severity of the condition and the patient's specific needs. Always consult with your healthcare professional for personalized advice.

Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Other side effects can occur. Check with your health care professional or read the information provided with your medication for additional side effect information.
