In plain language

Diverticular disease is a common digestive condition characterized by small pouches or sacs that form in the lining of the colon. These pouches, called diverticula, can become inflamed or infected, leading to a condition known as diverticulitis. While diverticular disease can affect people of all ages, it is more common in older adults.

Diverticular disease refers to conditions involving small, bulging pouches (diverticula) that can form in the lining of the digestive tract, most commonly in the colon. When these pouches become inflamed or infected, the condition is called diverticulitis.

The exact cause is not fully understood, but a low-fiber diet is thought to contribute by increasing pressure in the colon. This pressure can cause weak spots in the intestinal wall to bulge outward, forming diverticula.

Diverticulosis (the presence of diverticula) often causes no symptoms and may be discovered during routine screenings. Diverticulitis, on the other hand, can cause significant abdominal pain, fever, nausea, and changes in bowel habits.

Early intervention through diet and lifestyle changes can help prevent complications and manage symptoms effectively.

Key Information

Review the most relevant symptoms, risk factors, and common care approaches in one place.

Risk Factors

Several factors can increase the risk of developing diverticular disease, including:

  • Age: The risk increases with age, particularly after age 40.

  • Low-fiber diet: A diet low in fiber can contribute to the formation of diverticula.

  • Lack of exercise: Physical inactivity is associated with a higher risk of diverticulitis.

  • Obesity: Excess body weight increases the risk.

  • Smoking: Smoking may contribute to inflammation and complications.

Symptoms

The symptoms of diverticular disease can vary. Common signs include:

  • Abdominal pain: Usually on the lower left side.

  • Bloating: A feeling of fullness or swelling in the abdomen.

  • Changes in bowel habits: Constipation or diarrhea.

  • Fever and chills: Possible signs of an infection like diverticulitis.

  • Nausea: Sometimes accompanied by vomiting.

Coping Strategies

To help manage diverticular disease, consider the following strategies:

  • Increase fiber intake: A diet high in fiber can support bowel health and prevent constipation.

  • Hydration: Drinking plenty of fluids helps fiber work more effectively in the digestive system.

  • Regular exercise: Physical activity supports digestion and reduces pressure in the colon.

  • Avoiding trigger foods: Identify and limit foods that worsen symptoms, such as nuts or seeds (if advised by your doctor).

  • Monitoring symptoms: Track symptoms and report changes to your healthcare provider.

Common Treatments

Treatment for diverticular disease depends on the severity of symptoms. Mild cases may be managed with dietary changes and lifestyle modifications. More severe cases may require medication or surgery.

  • Medications: Antibiotics may be prescribed to treat diverticulitis. Pain relievers can help manage pain.

  • Diet: A high-fiber diet can help prevent constipation and reduce the risk of diverticulitis.

  • Surgery: In severe cases, surgery may be necessary to remove the affected portion of the colon.
