Diverticulitis
This 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, which may respond to antibiotics. A high-fiber diet can help. In more severe cases, it can cause abscesses, bleeding, and even perforations, resulting in severe pain, or even the need for surgery or a hospitalization.
