Diverticulitis is small, bulging sacs or pouches of the inner lining of the intestine that become inflamed or infected causing pain and disturbance of bowel function. Most often, these pouches are in the large intestine (colon). Diverticulitis cause when naturally weak places in your colon give way under pressure. It causes marble-sized pouches to protrude through the colon wall. Exactly how diverticulitis become inflamed or infected isn’t clear, when increase pressure in the colon it can weaken the wall of the diverticulitis, leading to an infection. Another is that the narrow opening of diverticulitis may trap fecal matter, which can also lead to infection. Or an obstruction in the narrow opening of a diverticulitis may reduce blood supply to the area, which can lead to inflammation. In the past, doctors thought nuts, seeds, popcorn and corn played a role in causing diverticulitis by getting trapped in the diverticulitis but these foods aren’t associated with an increased risk of diverticulitis.
People with diverticulitis can have many symptoms. Often pain is felt in the lower part of the abdomen. If you have diverticulitis, you may have fevers, feel sick to your stomach, vomit, or have a change in your bowel habits. Diverticulosis is very common. It is found in more than half of Americans over age 60. Diverticulitis is caused by small pieces of stool (feces) that become trapped in these pouches, causing infection or inflammation. People with diverticulosis often have no symptoms, but they may have bloating and cramping in the lower part of the belly. Rarely, they may notice blood in their stool or on toilet paper. Symptoms of diverticulitis are more severe and often start suddenly, but they may become worse over a few days. They include: * Tenderness, usually in the left lower side of the abdomen, Bloating or gas * Fever and chills * Nausea and vomiting * Not feeling hungry and not eating
