Diverticulosis is a medical condition characterized by the formation of pouches (diverticula) in the wall of the colon. These pouches are usually harmless, but they can become inflamed or infected, leading to a condition known as diverticulitis.

Causes

The exact cause of diverticulosis is unknown, but it is believed to be related to a low-fiber diet. Fiber helps to soften and add bulk to stools, which can prevent constipation and straining during bowel movements. Straining can cause pressure in the colon, leading to the formation of diverticula.

Symptoms

Many people with diverticulosis do not experience any symptoms. However, some people may experience mild symptoms such as bloating, gas, and mild cramps. If the diverticula become inflamed or infected, symptoms can include severe abdominal pain, fever, nausea, and a marked change in bowel habits.

Diagnosis

Diverticulosis is often discovered during routine colonoscopy or imaging tests for other conditions. If diverticulitis is suspected, a CT scan may be performed to confirm the diagnosis.

Treatment

Treatment for diverticulosis often involves dietary changes, such as increasing fiber intake. If diverticulitis occurs, treatment may include antibiotics, pain relievers, and in severe cases, surgery.

Prevention

Eating a high-fiber diet and drinking plenty of fluids can help to prevent diverticulosis. Regular exercise and avoiding straining during bowel movements can also help to reduce the risk.
