What is diverticulitis?


Symptoms, Diagnosis, and Treatment of Diverticulitis: What You Need to Know

If you experience abdominal pain or discomfort, constipation, diarrhea, or bloating, you may be at risk for diverticulitis. This condition is caused by the formation of small pouches or diverticula in the wall of the colon, which can become inflamed or infected. In this article, we’ll cover the symptoms of diverticulitis, who is at risk, how it’s diagnosed, potential complications, treatment options, and dietary recommendations.

Symptoms of Diverticulitis

The symptoms of diverticulitis can range from mild discomfort to severe pain and fever. Some of the most common symptoms include:

Abdominal Pain

Pain in the lower left side of the abdomen is the most common symptom of diverticulitis. The pain may be constant or come and go in waves, and may worsen after eating.

Changes in Bowel Movements

Diverticulitis can cause changes in bowel movements, including constipation, diarrhea, or alternating between the two. You may also experience bloating or gas.

Nausea and Vomiting

If the inflammation is severe, you may experience nausea and vomiting, along with a loss of appetite.

Fever and Chills

In more severe cases, you may develop a fever and chills, indicating an infection.

Who is at Risk for Diverticulitis?

Diverticulitis is more common in older adults, as the risk increases with age. Other factors that can increase your risk include:

  • Obesity
  • Lack of exercise
  • Smoking
  • A diet high in red meat and low in fiber
  • Family history of diverticulitis

How is Diverticulitis Diagnosed?

If you’re experiencing symptoms of diverticulitis, your doctor will likely perform a physical exam, including checking for tenderness in the lower left side of your abdomen. They may also order one or more tests to confirm the diagnosis, including:

  • CT scan or ultrasound to visualize the colon and identify any inflammation or infection
  • Blood tests to check for signs of infection or inflammation
  • Stool tests to rule out other conditions

Complications of Diverticulitis

Complications of diverticulitis can include:

  • Abscesses, or pockets of infected fluid
  • Fistulas, or abnormal connections between the colon and other organs
  • Intestinal blockages
  • Peritonitis, or inflammation of the lining of the abdominal cavity

Treatment of Diverticulitis

Treatment for diverticulitis depends on the severity of the condition. Mild cases may be treated with rest, pain medication, and a liquid or low-fiber diet until symptoms improve. In more severe cases, hospitalization may be necessary, and treatment may include:

  • Antibiotics to treat any infection
  • Surgery to remove the affected portion of the colon in cases of recurring or severe diverticulitis

Diet and Nutrition Recommendations for Diverticular Disease

If you have diverticulitis or are at risk for the condition, dietary changes can help manage symptoms and prevent future flare-ups. Some recommendations include:

  • Increasing your fiber intake through whole grains, fruits, and vegetables
  • Drinking plenty of fluids to help prevent constipation
  • Avoiding red meat, processed foods, and fried foods
  • Limiting your intake of caffeine and alcohol
  • Gradually increasing your fiber intake to prevent bloating and gas

What is Meckel’s Diverticulum?

Meckel’s diverticulum is a congenital condition that occurs in approximately 2% of the population. This condition is a small outpouching of the wall of the small intestine, near the junction with the large intestine. While many people with Meckel’s diverticulum may not experience any symptoms, some may develop abdominal pain, nausea, vomiting, or rectal bleeding. Treatment may involve surgery to remove the diverticulum if it is causing symptoms or complications.

In conclusion, diverticulitis is a condition that can cause discomfort, pain, and potential complications if left untreated. Knowing the symptoms, risk factors, and treatment options can help manage symptoms and prevent future flare-ups. In addition, dietary changes such as increasing fiber intake and avoiding certain foods can help manage symptoms and prevent future episodes. If you experience symptoms of diverticulitis, it is important to speak with your healthcare provider for proper diagnosis and treatment.
