Diverticulosis & Diverticulitis
Understanding and treating common colon conditions.
What Are Diverticulosis and Diverticulitis?
Diverticulosis is a condition in which small pouches (diverticula) form in the wall of the colon. It is very common — about half of people over age 60 have diverticulosis. Most people with diverticulosis have no symptoms and may never know they have it.
Diverticulitis occurs when one or more of these pouches becomes inflamed or infected. This can cause abdominal pain (usually on the lower left side), fever, nausea, and changes in bowel habits. Diverticulitis ranges from mild to severe and requires medical evaluation and treatment.
Symptoms of Diverticulitis
- Abdominal pain, typically in the lower left side
- Fever and chills
- Nausea and vomiting
- Change in bowel habits (constipation or diarrhea)
- Rectal bleeding (less common)
Treatment
Mild diverticulitis may be treated with antibiotics, a temporary liquid diet, and close monitoring. More severe cases may require hospitalization, IV antibiotics, or in some cases, surgery. After recovery, your doctor will discuss strategies to reduce the risk of recurrence, including dietary changes and, in some cases, a colonoscopy to evaluate the colon.
For diverticulosis without symptoms, a high-fiber diet is generally recommended to help prevent complications.
