Diverticulitis
According to the National Institute of Diabetes and Digestive and Kidney Disease, diverticulitis is an inflammation of “diverticula” or pockets that form in the lining of the intestine, usually the colon. “These look like punched-out holes in the lining of the colon that tend to get inflamed or obstructed with stool or other foreign material,” says Dr. Kaul.
Symptoms can include cramping in the lower abdomen, abscesses, bleeding, and even perforations.
