Diverticulitis Guide Common Symptoms

The symptoms of diverticulitis can be quite uncomfortable and vary in severity. It’s important to recognize these symptoms to seek timely medical attention for proper diagnosis and treatment.

One of the most common symptoms of diverticulitis is abdominal pain. This pain is typically constant and is often felt on the lower left side of the abdomen. However, in some cases, the pain may occur on the right side. The pain can range from mild to severe and may worsen with movement or pressure on the affected area.

In addition to abdominal pain, individuals with diverticulitis may experience nausea and vomiting. These symptoms are often the result of the inflammation in the digestive tract.

Fever is another common symptom of diverticulitis. The body may develop a fever as a response to the infection or inflammation in the diverticula. The fever can range in temperature and may be accompanied by other signs of infection, such as chills or sweating.

Abdominal tenderness is also a symptom of diverticulitis. The affected area may feel tender to the touch and may be sensitive or painful when pressure is applied.

Diverticulitis can also cause changes in bowel habits. Some individuals may experience constipation, while others may have diarrhea. These changes may be accompanied by bloating, gas, or cramping.


To summarize, the common symptoms of diverticulitis include:

  • Constant abdominal pain, typically on the lower left side
  • Nausea and vomiting
  • Fever
  • Abdominal tenderness
  • Changes in bowel habits, such as constipation or diarrhea

If you experience constant abdominal pain, especially if accompanied by fever and changes in bowel habits, it is important to seek medical attention. A healthcare professional can provide an accurate diagnosis and recommend appropriate treatment options.

Diverticulitis Guide Causes and Risk Factors

Diverticulitis occurs when weak areas in the colon allow pouches, called diverticula, to protrude through the colon wall. Several factors can increase the risk of developing diverticulitis.

Age and Weak Colon Wall

As people age, the colon wall naturally weakens, making it more susceptible to the formation of diverticula. This explains why diverticulitis is more prevalent among older individuals.

Obesity and Lack of Exercise

Being overweight or obese puts extra pressure on the colon, increasing the likelihood of diverticula development. Inactivity and a sedentary lifestyle also contribute to a weakened colon wall.

High-Fat, Low-Fiber Diet

A diet high in animal fat and low in fiber can lead to constipation, which in turn strains the colon. This strain creates weak areas where diverticula can form. Consuming a diet rich in fruits, vegetables, and whole grains helps maintain colon health and reduce the risk of diverticulitis.


Smoking damages the blood vessels and reduces blood flow to the colon, compromising its ability to heal and increasing the risk of diverticulitis.

Certain Medications

Long-term use of medications such as steroids and nonsteroidal anti-inflammatory drugs (NSAIDs) can contribute to the development of diverticulitis. These medications can increase the risk of inflammation and weaken the colon wall.

It is important to note that while these factors increase the risk of developing diverticulitis, they do not guarantee its occurrence. Conversely, individuals without these risk factors can still develop diverticulitis.

“Understanding the causes and risk factors of diverticulitis is crucial in managing and preventing this condition. By addressing these factors through lifestyle changes and appropriate medical interventions, individuals can reduce their risk of diverticulitis and improve their overall colon health.”

For a detailed overview of the causes and risk factors of diverticulitis, refer to the table below:

Causes and Risk Factors
Weak colon wall
Lack of exercise
High-fat, low-fiber diet
Certain medications (steroids, NSAIDs)

By understanding and addressing these causes and risk factors, individuals can take proactive steps towards preventing diverticulitis and promoting better colon health.

Potential Complications of Diverticulitis

While diverticulitis can cause significant discomfort and disruption to daily life, it can also lead to several potential complications that require immediate medical attention. It’s crucial to be aware of these complications and seek appropriate treatment to prevent further harm.

Abscess Formation

One potential complication of diverticulitis is the formation of an abscess within the affected pouch. An abscess is a collection of pus that develops due to infection. As diverticulitis progresses, the inflamed pouch can become filled with pus, leading to intense pain, swelling, and tenderness in the affected area. If left untreated, the abscess may rupture or cause further infections.

Bowel Blockage

Scarring and inflammation caused by recurrent episodes of diverticulitis can result in a bowel blockage. The accumulation of scar tissue within the colon may narrow the intestinal passage, making it difficult for feces to pass through. This can lead to symptoms such as severe abdominal pain, bloating, constipation, and even bowel obstruction. Prompt medical intervention is crucial to relieve the blockage and restore normal bowel function.

Fistula Development

In some cases, diverticulitis can lead to the development of an abnormal passageway, known as a fistula, between different sections of the bowel or other nearby organs. The inflamed diverticulum can erode through the adjacent tissues, creating a connection that shouldn’t exist. Fistulas can cause a variety of symptoms, including ongoing abdominal pain, changes in bowel habits, urinary tract infections, and even infections in other organs. It’s essential to address fistulas promptly to prevent further complications.


When an infected or inflamed diverticulum ruptures, it can lead to peritonitis. Peritonitis occurs when the contents of the intestine, including bacteria and stool, spill into the abdominal cavity. This condition can cause severe abdominal pain, tenderness, fever, nausea, and vomiting. Peritonitis is a medical emergency that requires immediate intervention to prevent life-threatening complications.

To visualize these potential complications, refer to the following table:

Abscess FormationA collection of pus in the inflamed pouch, causing intense pain and swelling.
Bowel BlockageScarring and inflammation causing obstruction in the intestinal passage, leading to abdominal pain and constipation.
Fistula DevelopmentFormation of an abnormal passageway between sections of the bowel or other organs, causing various symptoms.
PeritonitisInfection and inflammation spreading to the abdominal cavity, resulting in severe pain and systemic symptoms.

Knowledge is Key to Timely Intervention

Understanding the potential complications of diverticulitis is vital for early detection and prompt intervention. If you experience worsening symptoms or suspect any of these complications, it is essential to seek immediate medical attention to ensure proper evaluation and treatment.

Preventing Diverticulitis

To help prevent diverticulitis, it is recommended to exercise regularly to promote normal bowel function and reduce pressure in the colon. Eating a high-fiber diet, including fruits, vegetables, and whole grains, can also decrease the risk. Drinking plenty of fluids is important to prevent constipation. Avoiding smoking is also associated with a decreased risk of diverticulitis.

“Regular exercise, a high-fiber diet, adequate fluid intake, and avoiding smoking are key preventive measures for diverticulitis.”

Preventive MeasuresBenefits
Regular exercisePromotes normal bowel function and reduces pressure in the colon
High-fiber dietDecreases the risk of diverticulitis
Adequate fluid intakePrevents constipation
Avoiding smokingReduces the risk of diverticulitis

Diagnosis and Treatment of Diverticulitis

Diagnosing diverticulitis typically occurs during an acute attack when symptoms are present. Doctors utilize a combination of physical examination, blood tests, stool tests, and imaging tests, like CT scans or colonoscopy, to confirm the diagnosis of diverticulitis.

The severity of symptoms determines the appropriate course of treatment. For mild cases of diverticulitis, rest, diet changes, and antibiotics are commonly prescribed. Rest helps to relieve stress on the digestive system, allowing the affected area to heal. Diet changes may involve consuming a low-fiber or liquid diet to reduce strain on the digestive tract. Antibiotics are often prescribed to fight bacterial infection and reduce inflammation.


In situations where diverticulitis is severe or recurring, surgery may be necessary to remove the affected portion of the intestine. Surgery may also be recommended if complications, such as abscesses, bowel blockages, fistulas, or peritonitis, arise.
